Great bird app must to have

Love this app shows the different birds there sizes sounds they make and the different colors fun with my grandson who is 5 yrs old .Right now we are dealing with some New Humming Birds new colors just 4 days of just 4 now 12-15 flying around exciting all colors and all the rest of the birds we have nesting on mountain if you don't Have its a Must to have some of the hummingbirds are not showing up though on the list so I have to contact the company and let them know but I absolutely love this app and so does my grandson who has now turned six as of June but we have a blast doing this there is one mean hummingbird Orange with the white chest and he is territorial. Ruffo nope I think I spelled it wrong females have some green on them they look sort of like the Anna ones in away it's a first year we've had him there's also a black headed one it's new in our area with the white neck and a great body and they're beautiful also and the other new one it's just starting to get the purple neck we have gotten so many new breeds this year is fabulous in April we had over 25 different ones and now there's all the babies but those orange and white ones are attacking every single one because they think the feeders are all there's so we've had to put more feeders out but the app is great you have problems you just contact them.

GREAT Bird Identification for Boy Scout Bird Study/Fish & Wildlife Merit Badge

I highly recommend "Merlin Bird ID" App for Boy Scout "Bird Study" merit badge requirement 5 (Observe and be able to identify at least 20 species of wild birds) and requirement 6 (Explain the function of a bird's song. Be able to identify five of the 20 species in your field notebook by song or call alone. For each of these five species enter a description of the song or call, and note the behavior of the bird making the sound.) It would be great to be able record a sound and have the app identify the bird. Also on my wish list is the ability to tap on the picture of the bird and see a range map and add the picture and my personal pictures and bird song recordings to my personal album. My son successfully completed merit badge picture albums using this app. The creators have successfully enriched our lives as we watch the birds at our bird feeder. Go bless you!

Birding Enthusiasts

Living on a farm, surrounded by fields and forests, my husband and I are able to enjoy scores of nesting birds: Summer Tanagers, Blue Birds, Red-tailed Hawks, Indigo and Painted Buntings, Cardinals, Mockingbirds, Barn Swallows, Eastern Phoebes, House Wrens, and, to my husband's and my dismay, Brown-headed Cowbirds, as well as many other birds that come through the neighborhood. In the last two days, since downloading the Merlin ID App, we have identified a Mississippi Kite and another new type, too! The app is excellent! Kudos to you, Cornell Ornithology! (In the 70's, while my father was on Sabbatical at Cornell, our family became acquainted with your professor who specialized in eagles; I have delightful memories of visiting him, viewing his eagles!). Thank you for your excellent work! (of particular note is the "Bird Call"--Keith and I now have your handy reference [iPhones] at our fingertips to answer our many song-questions.)
