Cornell offers a free app on bird ID.... I downloaded it yesterday to our phone, and tried it this morning. I thought it would be helpful on vacation.

It is really nice. It asks you questions on size, color, etc and you push search and bingo up comes your bird. Right off is a portrait of the hawk I saw on Mother's day here...it is indeed a immature Red Tailed hawk! They compile data from people using the app too so I did the survey...it was really quick. And I felt useful participating in that in return for the free app.

It took ages to download, and I finally rebooted the phone and it then asked to install...so if it sticks like that for you...after 1/2 hr then just reboot. They ask for an email for you to confirm your use of the app which goes to your email. I suspect it is a research tool, gathering data on bird migration and movements etc.
