Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations).
Recording birds provides a permanent record of their vocalizations, and allows comparisons within and between individuals, sexes, ages, and species, over time and across habitats and behavioral contexts.

Apr 15, 2020 · The conspicuous nature of the vocal behavior of birds makes it a useful tool for monitoring populations and measuring biodiversity, but the importance of vocalizations in conservation goes beyond monitoring. Geographic song variants with population‐specific signatures, or dialects, can affect territory formation and mate choice.

Three ways to visualize a vocalization. Here, the “hey‐swee‐tie” song of a Black‐capped Chickadee (Poecile atricapillus) is represented three different ways: (C)Modern spectrograms often use color to represent sound intensity (the brighter the color, the higher the intensity).
Pure whistles in the song of the White‐throated Sparrow (Zonotrichia albicollis). Males sing whistled notes of distinct frequencies that are traditionally transcribed as “poor old sam peabody peabody peabody.” The individual triplet notes within each “pea‐bo‐dy” are easy to distinguish in the spectrogram, but more difficult to hear.
Woodpecker drumming differs by species. Many woodpeckers drum at a species‐specific rate that is easily discernible in spectrograms. Note the wide frequency range of the noisy sounds in the territorial drums of three different species: (A) Downy Woodpeckers (Picoides pubescens) drum at a rate of about 15 drums per second. (B) Hairy Woodpeckers (Pic...
Dissecting the components of a Common Yellowthroat (Geothlypis trichas) song. In the spectrogram, repeated “witchy” phrases are easy to discern. Each phrase can be further divided into three notes, “witch‐i‐ty.” You can hear these features even more clearly by comparing the normal song to recordings that have been slowed to half and quarter speeds....
Pacific Wren (Troglodytes pacificus) songs are remarkably complex. This spectrogram shows the diversity of elements in this tiny wren’s long and complicated song. Includes both regular and slowed (half and quarter) speeds, which reveal even more astounding detail. (A)Normal Speed (A)Half Speed (A)Quarter Speed

Birdsong, certain vocalizations of birds, characteristic of males during the breeding season, for the attraction of a mate and for territorial defense. Songs tend to be more complex and longer than birdcalls, used for communication within a species.
