2 days ago · Vocal activity period and cue rate are two aspects of vocal behaviour that are directly related to the temporal pattern of a bird's vocalization. Vocal activity periods are those times in a day when birds show heightened vocal activity (Aide et al., 2013). In full-day PAM recordings, more vocalizations will be captured when the vocal activity ...
3 days ago · In birds and human babies, the ontogeny of vocal learning shows striking parallels: Both are predisposed toward their species-specific signals at birth, require exposure to species-typical vocalizations during a “sensitive period,” and both are (traditionally) hypothesized to learn in two distinct phases ( 1 ).
22 hours ago · In general, these are the longer and more complex vocalizations that we think of as a “song,” but these can also be short and abrupt in some species. Almost all of the other noises that birds ...
3 days ago · The Role of Mimicry in Bird Vocalizations. Mimicry is a fascinating aspect of bird vocalizations, with species like the lyrebird known for their ability to mimic a wide range of sounds, including chainsaws and camera shutters. While some birds may mimic barking sounds, especially those living in close proximity to human settlements or alongside ...
4 days ago · Research on crow vocalizations has revealed that these birds have a remarkable ability to imitate a wide variety of sounds, including the human voice. Studies have shown that crows have a highly developed syrinx (the vocal organ of birds), which allows them to produce a wide range of vocalizations.
3 days ago · Outside of apes, research has focused on multisensory combinations during contexts including courtship (crickets 7; birds 8), agonistic interactions (frogs 9; Cichlid fish 10), and antipredator ...
2 days ago · Furthermore, limited information is available about the effects of other environmental or biological variables on vocalization rates of secretive marsh birds. The residency status of 70 Virginia Rails ( Rallus limicola ) and 25 Soras ( Porzana carolina ) was determined based on length of stay and time of year present and differences in call ...
