  1. Fwd: CA RSHA Rapid Territory Abandonment LINK
    DATE: May 3, 2017 @ 4:22pm, 7 month(s) ago
    All,
    
    See below for email message from noted bird guide artisit, birder, and
    
    naturalist John Schmitt re Red-shouldered Hawk 80 to 90 percent
    
    territory abandonment in SoCal.
    
    I think it would be good to learn through our observations if a decline
    
    is taking place elsewhere in California as well.
    
    Serving as the messenger for John Schmitt,
    
    Bob Barnes, Ridgecrest, Kern County, California

    Hi Bob,
    
    I learned of some troubling news about Red-shouldered Hawks; I was
    
    in San Luis Obispo County (Morro Bay, Montana de Oro, San Luis Obispo,
    
    Santa Margarita Valley/ Santa Margarita Lake-all prime Red-shouldered
    
    Hawk localities) on 26 APR leading some friends of mine on a short
    
    birdwatching tour (with a strong emphasis on raptors). We completely
    
    failed to either see or hear a single bird. I mentioned this to Peter
    
    Bloom (a well known long time raptor researcher) and his response was:
    
    "I'm not surprised". He went on to relate that there has been a severe
    
    population decline in Orange, Los Angeles, and San Diego Counties (80 to
    
    90 percent territory abandonment in some localities). Cause is
    
    uncertain, but Pete mentioned that some thought agrichemicals or West
    
    Nile Virus may be involved. So I will be taking special note of when
    
    and where I see/hear Red-shouldered here in the (Kern River) valley and
    
    I alert you to perhaps do the same and maybe pass the news on to others.
    
    Good chatting with you.
    
    Cheers, John
