Love all the various info available

This might not be the best app for a complete novice, but once you know enough to realize what two birds you want to compare, the app is fabulous.

Excellent…Daniel Edelstein, WarblerWatch.com

I cannot download this app to my telephone since it was updated. I previously had two copies of the older versions. Help me, please.

I’m sure I will discover more to like about this new version but for now let me applaud a couple changes: the four-character banding code now works! I suspect most birders once they discover the convenience of using these abbreviations of names will adopt their use. eBird supports their use as do most of the Birding apps. So I am happy to see this app incorporate their use. If you need more help with bird codes I recommend PEFA by Nemesis Code for an explanation and their look-up. Second, the “COMPARE” feature has been expanded. You are now shown all similar species and can select them one at a time to study similarities and differences. Before you had to know and select the two species to compare ... most likely overlooking one or more points of confusion. You can still compare two species of your choice even if they are not similar (e.g., CORA & SWHA, common raven & swainson’s hawk). This comparison example brings up a feature that would be helpful for birders who frequent HawkWatch sites: profiles of raptors and other large high flying birds are more useful for ID than close-up feather detail. Sibley demonstrates this usefulness in both species of this example. Perhaps a future version of his app will expand this feature to include all birds you are likely to find challenging at a HawkWatch. I use my phone app in the field and my tablet app for armchair bird study. Considering what I have invested in bird books over the past sixty years, this $10 was my Best Buy of the decade.

Audubon app has much more informed descriptions and has several variations of songs, along with diet, nesting habits and egg color, as well as conservation status.

A great aid to my day to day birdwatching life. Easy to use.

The only complaint is that it does with iPhone updates. Sometimes impossible to access songs as they are on top of each other. not keep up

Quintessential field guide for North America. Easy to navigate. Superior app to Merlin and Audubon. I am a field biologist and this is my go-to for referencing any and all species I come across in California.

So unbelievably useful to have excellent bird id at my fingertips!! Thanks Sibley.
