External stimuli and readiness to incubate in the bengalese finch
Animal Behaviour, 1967Abstract 1. (1) Pairs of Bengalese finches were tested for incubation by placing artificial eggs in their nest boxes before laying. The effects of varying degrees of deprivation of nest material were noted. 2. (2) Readiness to incubate is present in both sexes before egg-laying, but earlier in males than in females.

Social Facilitation in the Bengalese Finch
Behaviour, 1974AbstractObservations of paired male Bengalese finches showed that preening, feeding, beak-wiping, and drinking behaviour tended to be synchronised. There was also a strong tendency for one individual to sing whenever its companion began to feed. No synchrony of singing was found.

Population coding of song element sequence in the Bengalese finch HVC
European Journal of Neuroscience, 2008AbstractBirdsong is a complex vocalization composed of various song elements organized according to sequential rules. Two alternative views exist that explain the neural representation of song element sequences in the songbird brain. The finding of sequential selective neurons supports the idea that the song element sequence is encoded in a chain of ...

Contraception among Bengalese: Pattern, Preferences and Practicality
2020Does the fertility decline in West Bengal signify an early fall towards a one-child family which seems to have not happened in either Kerala or Tamil Nadu? The present study aims to understand the pattern of contraceptive use in West Bengal. Was the dual role of ‘target-achievement’ and ‘provision of incentives’ not effective in this state as it seemed

Song syntax changes in Bengalese finches singing in a helium atmosphere
NeuroReport, 2003Male Bengalese finches rely heavily on hearing to maintain adult songs and deafening a bird changes its song syntax immediately. Eight adult male Bengalese finches were placed in a helium atmosphere, which changes the resonance of the vocal tract. Undirected songs were recorded before, during and after this procedure, and the changes in song structure ...

Spatiotemporal properties of visual stimuli for song induction in Bengalese finches
NeuroReport, 2005Male Bengalese finches sing directed songs in response to video images of females projected onto a thin-film transistor monitor. We used this experimental paradigm to elucidate which properties of visual stimuli are important for eliciting singing. When video recordings of female Bengalese or zebra finches were used as visual stimuli, only images of ...

The Bengalese Finch: A Window on the Behavioral Neurobiology of Birdsong Syntax
Annals of the New York Academy of Sciences, 2004Abstract:The Bengalese finchLonchura striatavar.domesticais a domesticated strain of a wild species, the white‐rumped muniaLonchura striataof Southeast Asia. Bengalese finches have been domesticated in Japan for 240 years. Comparing their song syntax with that of their wild ancestors, we found that the domesticated strain has highly complex ...

The stimulus to egg‐laying in the Bengalese finch
Journal of Zoology, 1969The effects of mate and nesting facilities on the occurrence of egg‐laying were examined in the Bengalese finch.Egg‐laying is unusual in isolated females and those kept in large groups. It is more common in monosexual pairs, and its incidence in them is not markedly altered by whether males can be heard or not. Females in heterosexual pairs usually lay

Effects of background noise on acoustic characteristics of Bengalese finch songs
The Journal of the Acoustical Society of America, 2016Online regulation of vocalization in response to auditory feedback is one of the essential issues for vocal communication. One such audio-vocal interaction is the Lombard effect, an involuntary increase in vocal amplitude in response to the presence of background noise.

The Effect of Hormone Treatment Upon the Duration of Incubation in the Bengalese Finch
Behaviour, 1969AbstractNormal incubation behaviour, in particular its onset and termination, is discussed. The effects of treatment with prolactin, progesterone and oestrogen during the middle part of the incubation period are then described. While progesterone may interrupt incubation, oestrogen treatment tends to prolong this behaviour beyond the normal time of ...
