[Tweeters] Coop Stoop

[ED DEAL]

Sarah, 

After 10 years and a few thousand observation hours of over 350 Cooper's Hawk  nests in Seattle, I have been stooped perhaps a dozen times and never touched. This behavior is usually seen just in the few weeks when there are young in the nest.  The best study on the topic is the 2011 Master's Thesis by Kristin Madden "Factors Influencing Nest Site Defense Toward Humans by Cooper’s Hawks (Accipiter cooperii) in the Albuquerque Area." This is available on line through the UW Library.

My best advice is to wear a hat or carry an open umbrella and enjoy this rare event.

Best,
Ed Deal
