An electron microscope study on a neuro-endocrine complex in the proventricular mucosa of the finch, Uroloncha striata var domestica.

Variation in egg weight in the Bengalese finch (Lonchura striata var. domestica)

COLEMAN, R. M., and WHITTALL, R. D. 1990. Variation in egg weight in the Bengalese finch (Lonchura striata var. domestica). Can. J. Zool. 68: 272-275. Variation in egg weight was examined in 29 clutches (155 eggs) from 14 pairs of captive Bengalese finches. For clutches of four and seven eggs, egg weight varied more within than among clutches. The opposite was true for clutches of five, six, an...

S01-3 Neuro-ecology of song complexity in Bengalese finches

The Bengalese finch, Lonchura striata var. domestica, a strain derived from the wild white-rumped munia, Lonchura striata, has been under domestication in Japan for 240 years. We compared song syntax of these two strains and found that the domesticated strain developed highly complex, conspicuous songs, whereas the wild strain sang very stereotyped songs. To identify a possible neural substrate...

Fine structure of the Herbst corpuscles in the lingual mucosa of the finch, Lonchura striata.

The ultrastructure of Herbst corpuscles in the lingual mucosa of the finch, Lonchura striata var. domestica, was examined by light and electron microscopy. Numerous Herbst corpuscles were found at the top of connective tissue papillae just beneath the dorsal epithelium. The Herbst corpuscle was composed of an outer capsule, inner core and central axon. The central axon was discoid in shape and ...

Journal of Comparative Psychology A Comparison of Spontaneous Problem-Solving Abilities in Three Estrildid Finch (Taeniopygia guttata, Lonchura striata var. domestica, Stagonopleura guttata) Species

Selection, domestication, and the emergence of learned communication systems

One of the most distinctive characteristics of human language is the extent to which it relies on learned vocal signals. Communication systems are ubiquitous in the natural world but vocal learning is a comparatively rare evolutionary development (Jarvis, 2004). In this paper we take one example of this phenomena, bird song, which displays some remarkable parallels with human language (Doupe an...
