A European robin singing at dawn. The dawn chorus is the outbreak of birdsong at the start of a new day. In temperate countries this is most noticeable in spring when the birds are either defending a breeding territory, trying to attract a mate or calling in the flock. In a given location it is common for different species to do their dawn ...
Birds sing louder and at a higher pitch in urban areas, where there is ambient low-frequency noise. [58] [59] Traffic noise was found to decrease reproductive success in the great tit (Parus major) due to the overlap in acoustic frequency. [60] During the COVID-19 pandemic, reduced traffic noise led to birds in San Francisco singing 30% more ...
The opening birdsong is from a 1961 recording entitled "Dawn Chorus" and the single bird featured over the organ part is a nightingale also from 1961. Both featured on an HMV sound effects single (together with a recording of owls) but presumably the band just borrowed the originals from the EMI sound effects library as EMI owned HMV.
When alarmed they spread and droop their tail. They are active well after dusk and during the breeding season (April to August) they tend to sing during the darkness of dawn and dusk when few other birds are calling. The call precedes sunrise the most during November. [17] The alarm call is a shrill kree. The nest is a cup of moss and roots ...
In the absence of her mate, females are said to sing equally well. [15] Anxious birds utter a plaintive, descending peeeeeuu note, [4] for instance when their nestlings are threatened. [15] Like other robin-chats, they may mimic other birds. One individual has been noted to mimic a total of 36 bird species. [15]
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 territory. Nightingales sing even more loudly in urban or near-urban environments, in order to overcome the background noise.
The song's lyrics centre on the metaphor of the bird of dawning or morning that initiates a lament. As the song progresses, it appeals to the caged bird to sing and break free, [ 6 ] symbolising the termination of a period of oppression ("night") and the commencement of liberation ("day").
The Shelley's eagle-owl is a nocturnal bird which spends its days roosting in dense foliage, reportedly often at quite low levels in trees. [6] Few living wild specimens have ever been studied and until 2021 the species was never known to have been photographed in the wild. [ 10 ]
