Wonderful Local Bird Sighting and Identification Reference

I have used this app for a number of years now, but after a recent move to a new area I have enjoyed being able to use maps to look up where observations of the different birds have been made. I can look up observations made in my town, and can narrow that to regions within my town. Using this feature, I have confidently identified many of my observations. This summer I plan to utilize this app when I take vacation, so I can more enjoy the local birds. All in all, a great reference guide at my fingertips.

My favorite birding reference

The information in the app is easy to access and understand. I’ve had this app for a while and it has definitely improved over the years. The audio samples are particularly useful. Thank you for providing the public with a fun, educational tool to learn about birds.

All of the photos are clear, but occasionally - just often enough to be confusing - the caption seems at odds with the photo's subject. A bird that is obviously a juvenile - with juvenile feathers and coloring may be labeled "adult male" Categories are equally elastic, with questionable nearly identical photos appearing side by side for two different species. This is most pronounced in areas one wishes a definitive answer, such as "Which hummingbird (or woodpecker) am I looking at ?"

It's a cute app, perhaps suitable for a child - but not for serious birders.
