Help with Bird ID
 

I'm trying to identify a bird song I hear here in the Villages while sitting on my lanai in the early morning. It disappears about 6:20 AM when the day begins to brighten.

The sound is 5 clear staccato whistles, all the same “note”. No trills or change in rhythm from one to the next.

I've checked the visual and sound clips at the Florida Museum of Natural History site but haven't found what I'm hearing. Any birders out there with a suggestion?

Could it be the Common Nighthawk?

I listened to the various Nighthawk sounds but none sounded similar to the song I've been hearing in the AM. Thanks for the suggestion, however. - June

Blue birds are active at that time of day. Try Cornell Ornithology for good bird info and sounds and songs.

I do not know what bird you are hearing. If you buy the Smithsonian Field Guide To The Birds Of North America it contains a birdsong DVD with 148 different species of birds. Perhaps, you would recognize the song and be able to identify the bird your hearing. Its a wonderful book.

Could it be this....? I have had the Carolina Wren in my yard off and on, and I do think I usually hear it fairly early in the morning.

Even if this- Songs Calls, Bird Identification Skills, Bird ID -doesn't answer your questions directly, it is still so very interesting and educational. I hope you enjoy.

Again, thank you all for your suggestions. It's not the bluebird, Carolina wren or whippoorwill either. The Cornell site is a winner, bkcunningham1, and as I've searched and come up with other possibilities, it the one I go to to hear the songs/calls. You're right, its quite educational. - June

Here is something apparently recently released. It is supposed to ID your bird song for you via a smart phone. And it is free

Let us know if it works

how about the flycatcher...out here where i live they are one of the first birds i hear in the early morning...

That flycatcher certainly has a repertoire of calls, Barbara, but none of them are the one I hear in the AM.

Ironically, since finally posting this inquiry after hearing the song multiple AM's in a row, I haven't heard it for several days. I'm wondering if it was a migrant travelling north to its summer home. - June

eastern blue birds are up early as well...i can see you sitting out there waiting on them to chirp never come when you want them...grab a sound clip if you can and post...we will find out what that bird is lol...
