You know that birds are present because you can hear them, but the bird that you are trying to identify is always behind a leaf. This brings you to the next step in birding: This will add another dimension to your birding. As you enjoy re-identifying old friends and recognizing new ones by sight, you will be equally delighted in being able to recognize some by their songs and calls.
QUICK GUIDE TO BIRD SONGS
There are several aids that are available to assist you in this endeavor: One of the more satisfactory strategies is to associate some type of mnemonic with the bird sounds that you hear. For example, some birds seem to identify themselves by "saying" their names such as the Carolina Chickadee with its "chickadee-dee-dee" sound.
Others have distinct sounds such as the "drink-your-tea" of the Rufous-sided Towhee. Blending these sound helpers with the songs and calls of birds is both fun and helpful. Following is a list of 53 that might assist you in getting started.
- Warblers 1: Warbles & Chatters - east
- Unknown bird call - help requested.
These sound types were gleaned from a variety of sources. Field guides usually have helpers like these somewhere in the narrative. It's not exactly what you'd call pristine. It's a swath of cleared land that runs beneath towering electric power lines. The power poles don't seem to bother these birds.

In fact, they build their nests right underneath them. It's Thursday, June 14th, at 4: Byers spends the morning tromping up and down the hillside, tuning his ear to the birds and turning his tape recorder on and off and on again.
Trying to get on this bird, halfway between eight and nine. Byers uses a parabolic microphone which juts out from the center of a large plastic dish.
Any sound waves that hit the dish reflect back onto the microphone. This means he'll get a good recording without having to aim the mic precisely at the birds. This is what one of his recordings sounds like: After two breeding seasons, Byers has recorded hundreds of these mate attraction songs for each of the 56 male birds in this study. As he records, he identifies each singer by the multi-colored bands that he placed on the birds' legs earlier in the study.

This allows Byers to create a profile of each male's singing style and correlate that with the bird's reproductive success. To find out which males had the most offspring, he takes blood samples and compares the DNA of each chick with that of both parents from every nest in his study.
By early September, the chestnut-sided warblers are migrating to Central America where they spend the winter, and Byers goes back to his lab, a drab cinder block room at the University of Massachusetts in Amherst.
Byers is taking a close look at the songs of the males with the most offspring-- a very close look. Here, he's measuring frequency. And now we have this-- a graph has appeared on the screen. And what it shows is for each frequency of sound that appears in this song, how much energy the bird has put into that particular frequency in the sound.
After years of research, Byers has made a significant discovery: So if it's a high pitch, they're singing it at exactly that same high pitch time after time after time. Some birds vary it a little bit when they sing a series of songs of the same type.
The first one's high, the second one's maybe a little lower, and they're going high, low, high, low, high, high, low, and not keeping it consistent from song to song. Those birds have lower reproductive success.
These are preliminary results. Byers will spend the winter looking at other aspects of these songs such as whether each syllable is equal in length to every other syllable.
Living on Earth: Bird Songs
Such detailed analysis seems daunting, but Byers says understanding bird songs is worth it. They're among the most elaborate and complex vocalizations in the animal world, including humans, and just as we acquire language, songbirds acquire their songs.
They're not born knowing them; they have to learn them. How the songs develop and evolve is the bigger question that drives Byers' work.
