For my PhD dissertation at University of Delaware in Doug Tallamy's lab, I studied bird-insect food webs, and a part of that project entailed crowd-sourcing images of North American birds eating arthropod prey. Althouh I technically defended already, I'm still interested in collecting this kind of photo. If you have any photos that fit these criteria, please email them to me at email@example.com along with basic information about when & where the photo was taken (date, city, state/province; if you happen to know the ID of the arthropod prey, include that too!). There is also a Facebook page associated with this project, https://www.facebook.com/WhatDoBirdsEat/ if you are interested in seeing previous photo submissions.
Thanks in advance for any photos you can contribute!
