Mockingbirds often tend to vocalize in a long sequence of songs, permanently switching from one tonality to another. The Brown Thrasher seems to be more versatile than any other bird species when it comes to singing.
BIRDS SOUNDS SERIES
Source: 14 – White-throated Sparrow Crystallized SongĪfter song learning is completed, adult males sing a series of pure tones. Young birds struggle with the precise control of the syrinx and throat muscles. Source: 13 – White-throated Sparrow Plastic Song The American Bittern is known to produce bizarre sounds inflating the esophagus. Males of Anna’s Hummingbird produce a mechanical ‘chirp’ when diving that precedes the normal song. The White Stork probably produces the most widely known sound of bill-clattering. The Hairy Woodpecker has a higher drum rate than the Downy Woodpecker.
Ĭharacteristic non-vocal drum patterns of the Downy Woodpecker can be used for identification. The Wood Thrush creates one of the most complex sounds a bird can make with its impressive trills at the end of each song.
It is believed that the number of “dee”-notes in the Black-capped Chickadee call encodes the threat level posed by stationary predators of different sizes. The Black-capped Chickadee has a very simple song with only two notes. The Common Yellowthroat has a simple “chup” call given all year in alarm. The Common Yellowthroat has a quite complex song with a series of distinct notes. Īccording to Sibley Birds East, the calls in this sample can best be transcribed as toweeeowee toweeeowee. We can hear that the actual signal is richer than any of the transcriptions ever can be.
Transcriptions of bird songs in general remain ambiguous and often non-intuitive. 1 – American Goldfinch SongĪccording to Sibley Birds East, the song in this sample can best be transcribed as toWEE toWEE toWEE toWEE toWEE toWEE ti ti ti ti ti. The sample IDs listed below correspond with samples marked in the text of my thesis. The following samples of bird sounds are intended to illustrate the tremendous variety of bird vocalizations as part of my dissertation “Identifying Birds by Sound: Large-scale Acoustic Event Classification for Avian Activity Monitoring”.
