   Nazca Booby (Sula granti) - NABO (recent eBird sightings, view CBRC records)

  1. CBRC review and request for documentation LINK
    DATE: Oct 9, 2018 @ 3:54pm, 9 day(s) ago
    California birders, This has been a record year for boobies off the California coast. The California Bird Records Committee (CBRC) will begin reviewing the following records in mid November.
    Despite the fact that many of these birds were well seen and photographed, we have little or no documentation for most of these records. If you have any documentation to submit for these records, please do so as soon as possible. Feel free to forward this
    request to local listservs as appropriate. Thank you. Tom Thomas A. Benson Secretary, California Bird Records Committee MASKED BOOBY 2018-098 17 Aug 2018 Approx. 42.8 km W of Pt.

    CBRC evaluate records and archive documentation. Documentation may be submitted directly to the secretary via email ( secretary@... ) , or by using the online
    submission form ( http://www.californiabirds.org/report_sighting.html ). Media: This includes photos, audio recordings, and video. Photographs are usually the most useful documentation for evaluating records. If you have reasonably good (=identifiable)
    photos, please submit them. If possible, please crop the photos before submission so that the bird fills most of the frame. Also, please send originals whenever possible, and not screenshots or back-of-camera photos. How many photos should you submit That
    really depends on the record. If it is a long-staying rarity that is easily identifiable and seen by dozens of people, then a few photos (1-3 per person) are sufficient. If it is a mega-rarity that is difficult to identify and only seen by a one or few people,
    then send as many photos as possible that show the bird at different angles, postures, lighting, etc. Sometimes it is also useful to submit audio and/or video recordings of the bird, as some birds are more easily identified by their vocalizations. If relatively
    short, most audio recordings are small enough to be submitted via email; please submit those along with a brief note indicating the date and location of the recording. Large audio files and video files can be submitted by using a file sharing service; please
    contact the secretary if you need to submit a file that is too large for email. Written descriptions: Some written details should always be provided even the best photos should be accompanied by the name of the observer, the date, and the location,
    at a minimum. Sometimes a photo cant be obtained or vocalizations cant be recorded. In some cases, behaviors might be noted in the field that arent preserved well by photos. In these cases, it is helpful to submit a written description of the bird. Ideally,
    this description should be written as soon after observing the bird as possible; it is often helpful to make written notes in the field, or even dictate notes into the voice recorder on your smartphone while observing the bird, from which you can later generate
    a written description. The most important aspect of a written description is that you report only what you observed, and not a general description of the bird from a field guide. At a minimum, your description should include the date and location of the observation,
    and a description of the bird (size and structure, plumage, vocalizations, behavior). A brief discussion of how the bird was identified, and how similar species were eliminated is also helpful. Other useful information you might report includes optics used,
    distance from bird, lighting or weather conditions, length of time viewed, and other observers present.

  3. Got Boobies? We do!! Ventura pelagic trip on 6 Oct 2018 LINK
    DATE: Oct 6, 2018 @ 10:56pm, 12 day(s) ago
    We had a very successful trip out of Ventura today with Island Packers. I had one twisted pelagic fantasy when I loaded my gear on the boat this morning and by 4 pm we had fulfilled it...we had all five North American boobies on one trip!! I imagine we are the first trip to achieve this in the ABA area.
    
    We started at Anacapa Island where we found the continuing Masked Booby on the cliff faces. As we headed south from there we picked up on a distant booby south of Anacapa that we suspected was a Red-footed. Captain Joel floored it and we caught up the the bird, which was indeed a dark morph Red-footed Booby. From there we birded our way down to Santa Barbara Island where we found the continuing Brown Boobies there (80ish birds) with the bonus of a Blue-footed Booby amongst them. As we left the island number five had appeared to elude us, but as we swung around to the east side of the island we encountered a large feeding flock of Black-vented Shearwaters and other birds when soon after the cry of "black-and-white booby" rang out. We put the pedal to the metal one more time and ran down another booby. We eventually got close looks at the bird and noted the orangish bill...Nazca Booby! All five North American boobies on the same day...amazing! Perhaps a once in a lifetime birding event.
    
    Beyond the booby extravaganza, we had good fortune with a number of other birds including several large flock of Black-vented Shearwaters, which totaled in excess of 6,000 birds. These flocks had other shearwaters mixed in including Pink-footed, Buller's, and a Manx; numbers of attending jaegers (Pomarines and Parasitics); and others including Red-necked Phalarope, Common Murre, Cassin's Auklet, and Northern Fulmar. Deeper water south of the northern Islands had more shearwaters including one of the few Sooties we saw all day, Black and Ashy Storm-Petrels (and a Least seen by a few of us), Long-tailed Jaegers, Sabine's Gulls, Common Terns, and a number of Craveri's Murrelets. All in all a day that will be remembered by everyone there. Some birders got all five boobies as lifers, which is completely unfair to those of us that needed 49 years to see them all in the ABA Area. ;-)
    
    Thanks to Island Packers and Captain Joel Barrett for supporting our pelagic endeavors, and the leaders that helped today (Adam Searcy, Hugh Ranson, and Wes Fritz).
    
    We hope to get more trips on the schedule out of Ventura next year.
    
    Cheers

  5. Searcher Pelagic Results LINK
    DATE: Sep 7, 2018 @ 10:35pm, 41 day(s) ago
    Birders,
    The annual Searcher pelagic trip departed San Diego about noon on Labor Day and was back to the dock Friday morning at 730 AM. Highlights were many. Monday afternoon was spent crossing the 9 mile bank and working our way up the 30 mile. Highlights were excellent looks at a couple of Brown Boobies as well as close passes by a RED-FOOTED BOOBY. Ashy, Black, and Leach's Storm-Petrels, plus a few leaders and participants were able to glimpse and photo one or two LEAST STORM_PETRELS along the way.
    We decided to start day 2 at Santa Barbara Island where we saw the continuing immature NAZCA BOOBY plus about 80 Brown Boobies. From Santa Barbara we worked our way northwest along the Santa Cruz basin, seeing good numbers of Pomarine and Long-tailed Jaegers, Arctic Terns, as well as the expected shearwater species. We were treated to another RED-FOOTED BOOBY not too far from SB Island. In the late afternoon we arrived at a bank south east of San Miguel Island called "The Condor Bank" as it was a fishing spot frequented by the original Condor board from Santa Barbara. Here we encountered large boils of 200lb Bluefin Tuna, and the bird show was spectacular. Several South Polar Skuas, a dozen jaegers, many hundreds of Pink-footed Shearwaters and likely a hundred Arctic Terns. The show was spectacular, and here we found yet another immature NAZCA BOOBY and a couple of Brown Boobies.
    After anchoring near San Miguel for the night, DAY 3 we headed out to The Rodriguez Dome about 30 miles to the west. We departed Miguel about 5 AM, and were on the dome about 730 AM. Just before arriving at Rodriguez we encountered yet another immature NAZCA BOOBY. Exceptional numbers of Buller's Shearwaters, 8 Guadalupe Murrelets (seen well by all onboard) as well as our first Red-billed Tropicbird of the trip were highlights of our day headed south. We had as many as 10 Black-footed Albatross with us at once, and there were several behind the boarWe finished the day at the San Juan Seamount. We encountered dozens of Blue Whales in this deep water as well as some Fin whales, and a couple of cooperative BAIRD"S-BEAKED Whales. Guadalupe Fur Seals were seen regularly. Our first TOWNSEND"S STORM-PETRELS
    DAY 4 was spent traveling traveling from the western edge of the Tanner and Cortez Banks to the San Clemente Island basin. We found a cooperative RED-BILLED TROPICBIRD on the water, as well our first of nearly a dozen COOK'S PETRELS. Leach's Storm-petrels were present in numbers, and we were able to get folks on a handful of TOWNSEND's Storm-Petrels. Inside the Cortez we had the familiar cry of "White Booby behind the boat", and had an immature booby circle the boat. This one seemed to show characters of MASKED BOOBY, but this bird was not as straightforward as the others, so we will be sending photos out to get some expert opinions before putting this one in the books.
    As we approached Sam Clemente we were treated to one of the most spectacular afternoons I have ever spent at sea. Boils of smaller bluefin tuna were everywhere, and there were literally thousands of Pink-footed Shearwaters wheeling about, as well as. hundreds of Arctic and Common Terns, dozens of Sabine's gulls and jaegers were in flight. We also saw about 35 Craveri's Murrelets in this area, some very close to the boat allowing great looks. We poked through flock after flock of birds until dark, eventually getting brief looks at a FLESH_FOOTED SHEARWATER. In the middle of this feeding frenzy we also saw yet another NAZCA BOOBY, this one a full adult.
    The high overcast conditions were also good for migrants, and we had Willow Flycatcher, Macgillvray'a Warbler as well as Orange-crowned, Townsend's, Black-throated Gray as well as multiple cowbirds and several species of shorebird.
    One of the best trips I have done off SoCal and certainly continues the excellent results this year. Thanks to Celia Condit and Captain Art Taylor from Searcher Natural History Tours, my co-leaders Dave Pereksta, Dave Povey, and Rob Hynson. Thanks to all the participants as well.

    Nazca is on the beach across from the Neptune's Net restaurant. It was preening when I got here and apparently ate a fish just before that, but it is now laying down. Not sure if it is healthy. We are keeping people and dogs away, but may want to get here soon.

  15. Ventura pelagic trip report - 15 July 2018; multiple megas! LINK
    DATE: Jul 20, 2018 @ 7:32am, 3 month(s) ago
    I am finally getting a trip report out from Sunday's pelagic trip out of Ventura with Island Packers. We had some exceptional birds and photos of several storm-petrels have revealed that we had better birds than we knew. I will not go in to exhaustive detail of every segment of the trip, but will hit the highlights.
    
    We left Ventura on the Island Adventure and headed across the channel to Anacapa Island. Although there has not been any boobies on Anacapa yet in 2018, we had to look anyway and were stunned to find a Nazca Booby sitting on top of the arch! The bird sat there and preened in front of us for 20 minutes before we moved on. This is just the second Ventura County record (of a live bird) and one of less than 20 for California and North America. The day can't get any better than that...right Well maybe it did. We continued along the south shore of Anacapa Island where we found an American Oystercatcher in a place where we have seen them on past trips. Another California rarity and still before 9 am. You are welcome Logan.
    
    We then headed south of the islands to the areas we have been exploring on recent July trips. There were impressive numbers of Sooty and Pink-footed Shearwaters along the majority of the route and while riding a steep contour line to the south, the first scream of "Cook's Petrel!!" rang out for the day. Another was screamed out soon thereafter, but these first two were elusive and not seen by many. This is when the trip leader starts sweating bullets, but not to worry as we hit a steady stream of Cook's Petrels eventually getting some close passes and even small groups sitting on the water. Our ride south was littered with petrels and shearwaters. We also found a few late Scripps's Murrelets that Captain Jimmy expertly crept up on and allowed everyone on board to get great looks.
    
    After just crossing back into Ventura County waters, we found a large flock of storm-petrels sitting on the water (100+) that we crept up on. As we approached the flock a storm-petrel passed closely across the bow that I yelled out so the people in the bow could get on it. I shot a few photos since it was close and the verdict from the bow at the time was a dark-rumped Leach's Storm-Petrel. I will come back to this bird later. The flock flushed as we approached and the birds dispersed quickly. While the flock was primarily Ashy and Black Storm-Petrels, a small bird with a big white rump was seen briefly by only a few people before it disappeared. Some captured this bird in their photos of the flock and later analysis and consultation with experts proved it to be a Wedge-rumped Storm-Petrel! This is only the 14th record for the state, but most of the boat including myself did not see it. Thankfully some managed to get photos. While going through my photos of the flock, I found an apparent Fork-tailed Storm-Petrel that also eluded detection.
    
    As we continued on we had more storm-petrels including a few Townsend's, and a steady stream of shearwaters and the occasional Cook's Petrel. Several Long-tailed Jaegers and a South Polar Skua were also highlights. We eventually turned east and headed towards Santa Barbara Island to check the status of Brown Boobies at this little visited island. After running across several more Cook's Petrels that were farther east than we have ever seen in the region, we were several miles off the island when someone on the boat shouted "booby!" While I expected to see our first Brown Booby of the day, I was shocked to see a large white booby flying straight for the boat...our second Nazca Booby of the day!! Second record for Santa Barbara County and a very happy cadre of SBCo listers. The island did not disappoint as we had 50 Brown Boobies at Sutil Rock with several pairs exhibiting courting behavior. Hard to believe this species was rare in the region until just a few years ago. Upon leaving the island we started our slog back to Ventura against the swell and although the birds dropped off late in the day, we did have stellar looks at several Long-tailed Jaegers. Other birds seen throughout the day included Northern Fulmar, Black-vented Shearwater, Leach's Storm-Petrel, Cassin's Auklet, Common Murre, Rhinoceros Auklet, Pigeon Guillemot, Sabine's Gull, Red Phalarope, and Red-necked Phalarope.
    
    After getting home and not looking at any of my photos until Monday, I found my photos of the storm-petrel that crossed our bow and nearly had a heart attack. The camera captures what the eye can't see in an instant, and the photos revealed a stocky storm-petrel with a deeply forked tail, pale rump and back, bright carpal bars, and a contrastingly dark head. The field marks suggested this bird was likely a Markham's or a Tristram's Storm-Petrel. Upon consulting with a few experts who are familiar with these species, the responses came back overwhelmingly that the bird in question was a Tristram's Storm-Petrel! If accepted, this would be the first record of a free-flying bird in North American waters. We saw one on a 2007 July trip that was rejected by the CBRC, and two have been captured in mist nets on the Farallon Islands in recent years. I already posted a photo on Facebook and will cross post it to several lists. Our team will work up a submission to the CBRC.
    
    This was an amazing trip and we could not do it without the unwavering support of Island Packers and their staff. Joel Barrett and his passion for birds makes these trips happen on their end and we could not do it without him. Captain Jimmy McWaters handled the boat and got us on birds like the seasoned expert he is. Thanks also go out to Leanne Kleinsmith and Sam the whale man for their support to passengers throughout the day. Our leaders/spotters did a spectacular job finding birds and getting people on them all day so special thanks to Todd McGrath, Adam Searcy, Peter Gaede, Hugh Ranson, Wes Fritz, and Bernardo Alps.
    
    Our next scheduled trip is Oct 6, 2018 although we are discussing a chase trip out to the area where we had Cook's Petrels and storm-petrels. If we can get something scheduled I will announce it out to the listserves. Stay tuned.

  21. Upcoming pelagic trip out of Ventura on July 15 LINK
    DATE: Jul 3, 2018 @ 10:55am, 4 month(s) ago
     Hi All
    
    This is a reminder that Island Packers is offering a 12-hour
    deepwater pelagic trip from the Ventura Harbor at 7 am on Sunday July 15. This trip will allow us to get to offshore
    waters beyond the reach of most day trips where we will have a chance to see a
    number of outstanding pelagic birds and marine mammals. Our intention is to go southwest from Ventura
    towards San Nicolas Island and the banks, knolls, canyons and other productive
    features in the area. This will give us
    a chance to look for sought after species like Cooks Petrel, Red-billed
    Tropicbird, Least Storm-Petrel, Leach's Storm-Petrel, Townsend's Storm-Petrel,
    Guadalupe Murrelet and Craveri's Murrelet.
    Our trip to this area last year was outstanding and yielded Cooks
    Petrels, Black-footed Albatross, 45 Craveris Murrelets (!!), Brown Booby, and
    a variety of other pelagic species. Recent pelagic trips out of San Diego have
    found Craveris Murrelets, Nazca Booby, Masked Booby, and Townsends
    Storm-Petrel so there are some great birds in the Southern California Bight at
    the moment. We will decide what our offshore destination will be after
    reviewing oceanographic conditions at the time of the trip, which will help
    determine where the birds and other marine life may be present or concentrated.
    
    Summer trips in July and August coincide with the earlier
    parts of the southbound fall migration of arctic nesting species, the northward
    dispersal of southern nesting species, and the nesting and fledging periods of
    breeding species on the Channel Islands.
    Past trips have found Cooks Petrel (rare), Manx Shearwater (rare),
    Black-footed Albatross, Laysan Albatross (rare), Buller's Shearwater, Leach's
    Storm-Petrel, Blue-footed Booby, Brown Booby, Long-tailed Jaeger, South Polar
    Skua, Scripps's Murrelet, Craveri's Murrelet, Arctic Tern, and a variety of
    other shearwaters, storm-petrels, pelagic gulls and terns, phalaropes, and
    alcids. Patrolling the shoreline of
    Anacapa Island has yielded American Oystercatchers over the last few
    years. Summer is also an excellent time
    for Ashy and Black Storm-Petrels, and Cassin's Auklets. There is often a flock of 1000's of Black
    Storm-Petrels south of the islands that we will attempt to find. A few Rhinoceros Auklets and Common Murres
    should still be around, along with Pigeon Guillemots near the islands. Red-billed Tropicbird is always possible on
    summer trips, although not found every year.
    
    The trip will be on an ultra-fast catamaran that features a
    spacious and comfortable cabin, galley, and excellent viewing from both the
    upper and lower decks. A full contingent of outstanding seabird leaders will be
    present to make sure we see all that is out there. The Captain and crew know how to run birding
    trips and are enthusiastic and helpful.
    In addition, we work hard to creep up on birds and get them in the right
    light...photographers will not be disappointed!
    
    Trips can be booked over the phone by calling (805) 642-1393
    or online at www.IslandPackers.com by clicking the Reserve Trip tab, select the
    Special Trips tab, and select your desired departure. The cost of the trip is
    $195 per adult.
    
    Hope to see you at sea!

Cabrillo, SD (single observer, documentation complete) What kind of documentation should one submit to the CBRC Following are some guidelines for submitting media and written descriptions that will be useful for helping the CBRC evaluate records and archive documentation. Documentation may
    be submitted directly to the secretary via email ( secretary@... ) , or by using the online submission form ( http://www.californiabirds.org/report_sighting.html ). Media: This includes photos, audio recordings, and video. Photographs are usually the most useful documentation for evaluating records. If you have reasonably good (=identifiable) photos, please submit them. If possible, please crop the
    photos before submission so that the bird fills most of the frame. Also, please send originals whenever possible, and not screenshots or back-of-camera photos. How many photos should you submit That really depends on the record. If it is a long-staying rarity
    that is easily identifiable and seen by dozens of people, then a few photos (1-3 per person) are sufficient. If it is a mega-rarity that is difficult to identify and only seen by a one or few people, then send as many photos as possible that show the bird
    at different angles, postures, lighting, etc. Sometimes it is also useful to submit audio and/or video recordings of the bird, as some birds are more easily identified by their vocalizations. If relatively short, most audio recordings are small enough to be
    submitted via email; please submit those along with a brief note indicating the date and location of the recording. Large audio files and video files can be submitted by using a file sharing service; please contact the secretary if you need to submit a file
    that is too large for email. Written descriptions: Some written details should always be provided even the best photos should be accompanied by the name of the observer, the date, and the location, at a minimum. Sometimes a photo cant be obtained or vocalizations
    cant be recorded. In some cases, behaviors might be noted in the field that arent preserved well by photos. In these cases, it is helpful to submit a written description of the bird. Ideally, this description should be written as soon after observing the
    bird as possible; it is often helpful to make written notes in the field, or even dictate notes into the voice recorder on your smartphone while observing the bird, from which you can later generate a written description. The most important aspect of a written
    description is that you report only what you observed, and not a general description of the bird from a field guide. At a minimum, your description should include the date and location of the observation, and a description of the bird (size and structure,
    plumage, vocalizations, behavior). A brief discussion of how the bird was identified, and how similar species were eliminated is also helpful. Other useful information you might report includes optics used, distance from bird, lighting or weather conditions,
    length of time viewed, and other observers present.

  25. Origin & age of banded Nazca Booby in San Diego County waters June 10, 2018 LINK
    DATE: Jun 15, 2018 @ 4:21pm, 4 month(s) ago
    On the last San Diego Pelagics
    trip this past Sunday June 10, 2018 we had the good fortune to
    find a subadult NAZCA BOOBY sitting on the water about 8:20am. Per GPS
    readings the exact location 5.5NM west of Imperial Beach and 1.1NM from Mexican
    waters to our south. The booby was spotted just as we motored up very
    close to it, maybe somehow it was hidden behind a swell, and we immediately
    stopped the boat and got very close looks at the bird. The bird
    was so close in fact that when it took off flying, luckily towards us and along the
    starboard side in front of assembled photographers, from the many photos taken
    a metal band could be clearly seen on the right leg. You have to marvel
    at modern camera sensors because images so detailed a
    partial band number could be read. The information on the band appeared
    to show a number or alphanumeric either "734.." or "73A.."
    visible. You can see the photos on our eBird checklist here https://ebird.org/view/checklist/S46508705 I checked in with Kimball Garrett
    about the rehabbed Nazca/Masked Booby that had been released at San Pedro, Los
    Angeles County on Oct 9, 2015 but should have read his original email to the
    LACOBIRDS listserv first since this bird banded with USGS metal band on left
    leg. The San Diego
    bird, a subadult evidenced by some dark speckling on the white upperparts, also inconsistent
    considering age. Kimball confirmed the band did not match that of the San
    Pedro released bird with USGS band (with number 1038-26057). A second photo of the San Diego
    Nazca Booby then surfaced showing the band even more clearly and with an upper
    line possibly showing word "ANDER...". I had a hunch about
    where the band may have come from and reached out to Professor Dave Anderson at
    Wake Forest University who has been studying Nazca Booby and other seabirds in
    the Galapagos for the past 35 years. Sure enough, Dave confirmed the band
    originated from his lab and he could trace the partial number (734xx) of this
    Nazca Booby to an immature banded on Isla Espanola, Galapagos Islands, in the
    first half of 2017. He estimates the bird's age at 1 3/4 years old at time
    of sighting here in San Diego. He told
    me they have banded about 25,000 youngsters (Nazca Booby) and this is the
    71st report of one of their banded birds
    but the most northerly by 7 degrees of
    latitude. Dave noted that most band returns are of 1-2 year old
    birds from the Pacific coast of Central America. The age estimate, 21 months, seems low
    perhaps . You can see P7 or P8 growing,
    at least on the right wing, and this would seem to peg the bird, in 2nd-prebasic primary molt, in a 2526
    month age range using a Masked Booby molt pattern shown in Howell, 2010, Molt
    in North American Birds. I looked in Howell
    et al. 2014, Rare Birds of North America, and it states, under Nazca Booby, pp.
    117-11 9, 2nd- prebasic primary molt starting about 14 months
    after fledging, i.e. about 18 months of age. Considering
    the six or seven visible grown primaries, at about a month apiece, this would get us to
    2425 months. Maybe the discrepancy can be accounted for with individual variation or the original estimate is a bit lightweight.
    I will have to look around for Nazca Booby molt publications to understand the variation and check on this again with Dave Anderson . I will be submitting these complete
    details to the CBRC along with photographs showing the band number and plumage
    details of the booby. A credit due photographers Matthew Binns and Todd McGrath capturing images of the band. We have three more pelagics out of
    San Diego planned for 2018. Details can
    be found at the website http://www.sandiegopelagics.com
    and space is still available but August is filling up fast. In addition to Nazca Booby last Sunday we
    also found the much sought-after TOWNSENDS STORM-PETREL photos here https://ebird.org/view/checklist/S46508696
    our next trip in August a good opportunity for this species.

  29. Re: [CALBIRDS] Masked Boobies - white in tail LINK
    DATE: Jan 25, 2018 @ 2:20pm, 9 month(s) ago
    FWIW, Nazca Boobies were quite common attending our cruise ship off Mexico
    
    and Middle America last month. Most were adults. Here are some Nazca Booby
    
    photos including two photos of an immature off Nicaragua.
    
    https://fog.ccsf.edu/~jmorlan/LA2Chile-Dec2017/NazcaBoobyIMG_9258.htm
    
    Scroll down for the immature bird showing fairly extensive white in its
    
    tail. Both photos are of the same individual which I judged to be late in
    
    its first cycle. In my experience bill color seemed to change depending on
    
    light and angle.

This amount of white in the tail seems to be the exception in Masked Booby, and certainly many Nazca Boobies have more extensive and conspicuous white in the tail. However, the CBRC has been wrestling with some records of subadult Masked/Nazca Boobies with about as much white in the central rectrices as on the bird in the link above, and with adult bill color just barely beginning to show, so we've been interested in whether that amount of white points to Nazca and eliminates Masked - apparently it does not.

    >Your comments about juvenile Nazca Boobies already showing extensive white in the tail are interesting, and we were wondering whether juvenile Masked Boobies ever show extensive white in the tail or whether juvenile Masked Boobies are always dark-tailed. "Always" and "ever" are tricky words - there is still much we need to learn about variability in Masked and Nazca Boobies, so it may not be possible to know the extremes, but I'd be interested in any photos of juvenile Masked Boobies (i.e., Masked/Nazca types well away from Nazca breeding range) showing white in the central recs.
