June is a wonderful time a year for birders with the air filled with the marvelous songs of many birds.\u00a0 The morning chorus is truly a feast for the ears.<\/p>\n
Let\u2019s start by considering the important distinction between a bird song and a bird call.\u00a0 Songs are complex vocalizations, usually associated with reproduction.\u00a0 Males sing and females typically do not although Northern Cardinal and Painted Bunting females are among the exceptions to the rule.<\/p>\n
Calls on the other hand are simple vocalizations, usually given by all members of a species.\u00a0 The calls are generally instinctive so do not need to be learned.\u00a0 Calls can be used to keep contact with other flock members and to sound alarms.<\/p>\n
The largest order of birds is the Passeriformes, often shortened to the passerines.\u00a0 The passerines contain 60% of all bird species.\u00a0 The passerines are subdivided into two major groups: the suboscines (flycatchers and their relatives) and the oscines \u00a0(songbirds).\u00a0 Suboscines have very simple songs like the \u201cFEE-bee\u201d song of the Eastern Phoebe.\u00a0 The songs of suboscines are innate so do not need to be learned.\u00a0 Oscines with must generally learn their complex song from their father or a neighboring male.<\/p>\n
Songbirds comprise some 4,000 species, many of which are vocal virtuosos.\u00a0 However, songs are known in other orders of birds.\u00a0 Hummingbirds are one such group.\u00a0 Anna\u2019s Hummingbird has a 10-second long song, pretty impressive for such a small bird.<\/p>\n
In the last column, I wrote about the cheating that often goes on with birds in a seemingly monogamous relationship.\u00a0 Not surprisingly, bird song plays a role in these soap operas.\u00a0 A male sings for two reasons: to attract females to his territory and to warn other males to stay out of his territory.<\/p>\n
In some birds, distinctive songs are sung for these two functions.\u00a0 The Black-throated Green Warbler provides a nice example.\u00a0 Male song is often written as \u201czee-zee-zee-zoo-zee\u201d with the final zee given with great emphasis.\u00a0 This song is referred to as the accented song.\u00a0 It is sung for the purpose of attracting a female.\u00a0 The male is essentially proclaiming his bachelor status and desire to enter into a relationship.<\/p>\n
An alternate song is heard that can be rendered as \u201czee-zee-zoo-zoo-zee\u201d or \u201ctrees-trees-whispering-trees\u201d.\u00a0 This song is called an unaccented song and is directed at neighboring males to deter those males from visiting a male\u2019s territory and perhaps mating with his partner.<\/p>\n
You may find it useful to visit www.allaboutbirds.org and search for Black-throated Green Warbler.\u00a0 Click on the Sound tab.\u00a0 The first song is the accented song and the second is the unaccented song.<\/p>\n
Chestnut-sided Warblers provide another example of males that have both an accented and unaccented song.\u00a0 The accented song is often written as \u201cpleased-pleased-pleased-to-MEETCHA\u201d.\u00a0 The unaccented song lacks the explosive final two syllables.\u00a0 The allaboutbirds.org site has a recording of the accented song.<\/p>\n
Some songbirds vary their song over the course of a day.\u00a0 American Robins are usually the first local species to start singing in the morning, often as early as 3 PM much to the dismay of some would-be sleepers.\u00a0 The song of a robin is a series of two- and three-note phrases, delivered in a sing-song style.\u00a0 The dawn version of the song is generally a bit faster.\u00a0 The birds also include a soft, whisper-like phrase that is aptly described as \u201chisselly\u201d.\u00a0 During the later part of the day, the song is sung more slowly and the \u201chissely\u201d phrase disappears.\u00a0 We have no idea at this point of the importance of the \u201chissely\u201d phrase.\u00a0 The allaboutbirds.org site has recordings of both the dawn song and the daytime song.<\/p>\n
Eastern Phoebes sing their fairly simple \u201cFEE-bee\u201d song during most of the day.\u00a0 However, early in the morning, they add an extra syllable, to sing \u201cFEE-buh-bee\u201d.\u00a0 Listen for that variation from your local phoebe.<\/p>\n
