xeno-canto is a citizen science project and repository in which volunteers record, upload and annotate recordings of bird calls and sounds of orthoptera and bats. [2] Since it began in 2005, it has collected over 575,000 sound recordings from more than 10,000 species worldwide, and has become one of the biggest collections of bird sounds in the world. [1]
The red-winged blackbird (Agelaius phoeniceus) is a passerine bird of the family Icteridae found in most of North America and much of Central America. It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico, and Guatemala, with isolated populations in western El Salvador, northwestern Honduras, and northwestern Costa Rica.
Red-winged blackbird: North and much of Central America Agelaius assimilis: Red-shouldered blackbird: Cuba Agelaius tricolor: Tricolored blackbird: Pacific coast of North America, from Northern California in the U.S. (with occasional strays into Oregon), to upper Baja California in Mexico. Agelaius humeralis: Tawny-shouldered blackbird
The species' call sounds slightly more nasal than that of the red-wing's - a nasal kip and a sharp check. The male's song is a garbled on-ke-kaaangh. The bird migrates south during the colder seasons to Mexico and back to northern California during the warmer seasons.
The downy woodpecker gives a number of vocalizations, including a short pik call. One may identify the woodpecker by the pik-call, counting half a second between piks (a total of four must be heard). The rattle-call is a short burst that sounds similar to a bouncing ball, while that of the hairy woodpecker is a shorter burst of the same amplitude.
It is generally agreed upon in birding and ornithology which sounds are songs and which are calls, and a good field guide will differentiate between the two. Wing feathers of a male club-winged manakin, with the modifications noted by P. L. Sclater in 1860 [4] and discussed by Charles Darwin in 1871. [5] The bird produces sound with its wings.
Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. The name, meaning " jaundiced ones" (from the prominent yellow feathers of many species) comes from the Ancient Greek ikteros via the Latin ictericus .
