I never really considered myself as a birder until I noticed that I was keeping a list of all the birds that visited my backyard. Many years ago there were a lot, but lately there has been a drastic drop in the number and variety. Most likely cause would be the loss of habitat in other areas.
The National Wildlife Federation (US) published some photos in the latest edition of the magazine. One shows a red winged blackbird singing. The three notes of its song are visible as condensation of the breath. In the photo you can see the three notes.

It is the 12th photo. Looks purty neet.
