Some birds will respond to a shared song type with a song-type match (i.e. with the same song type). [24] This may be an aggressive signal; however, results are mixed. [23] Birds may also interact using repertoire-matches, wherein a bird responds with a song type that is in its rival's repertoire but is not the song that it is currently singing ...
Its song is particularly noticeable at night because few other birds are singing. This is why its name includes "night" in several languages. Only unpaired males sing regularly at night, and nocturnal song probably serves to attract a mate. Singing at dawn, during the hour before sunrise, is assumed to be important in defending the bird's ...
The common blackbird (Turdus merula) is a species of true thrush. It is also called the Eurasian blackbird (especially in North America, to distinguish it from the unrelated New World blackbirds), [2] or simply the blackbird where this does not lead to confusion with a similar-looking local species.
Learned vocalizations have been identified in groups including whales, elephants, seals, and primates, however the most well-established examples of learned singing is in birds. [29] In many species, young birds learn songs from adult males of the same species, typically fathers. [30] This was first demonstrated in chaffinches (Fringilla coelabs).
In the milder areas where some birds stay year round, the resident male remains in his breeding territory, singing intermittently, but the female may establish a separate individual wintering range until pair formation begins in the early spring. [25] During migration, the song thrush travels mainly at night with a strong and direct flight action.
There are many birds that are active nocturnally. Some, like owls and nighthawks, are predominantly nocturnal whereas others do specific tasks, like migrating, nocturnally. North Island brown kiwi, Apteryx mantelli [1] Black-crowned night heron, Nycticorax nycticorax [1] Short-eared owl, Asio flammeus [1] Long-eared owl, Asio otus [1]
Male blackcaps will sometimes sing even when incubating, especially with the second brood. This appears to be intended to maintain the bond with the female. [21] Wintering birds in Africa are quiet initially, but start singing in January or February prior to their return north. [22] [23]
The slightly smaller female is 23 cm (9.1 in) long and weighs 95 g (3.4 oz). The adult plumage is entirely black with a bluish gloss, and the bill, legs and feet are also black. The iris is brown. Females are identically plumaged to the males; young birds are brownish black and lack iridescence. There are no subspecies.
