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...
متن کاملA comparison of spontaneous problem-solving abilities in three estrildid finch (Taeniopygia guttata, Lonchura striata var. domestica, Stagonopleura guttata) species.
Cognition has been extensively studied in primates while other, more distantly related taxa have been neglected for a long time. More recently, there has been an increased interest in avian cognition, with the focus mostly on big-brained species like parrots and corvids. However, the majority of bird species has never systematically been studied in diverse cognitive tasks other than memory and ...
متن کاملAdult Bengalese finches (Lonchura striata var. domestica) require real-time auditory feedback to produce normal song syntax.
Songbirds develop their songs by imitating songs of adults. For song learning to proceed normally, the bird's hearing must remain intact throughout the song development process. In many species, song learning takes place during one period early in life, and no more new song elements are learned thereafter. In these so-called close-ended learners, it has long been assumed that once song developm...
متن کاملSyringeal Specialization of Frequency Control during Song Production in the Bengalese Finch (Lonchura striata domestica)
BACKGROUND Singing in songbirds is a complex, learned behavior which shares many parallels with human speech. The avian vocal organ (syrinx) has two potential sound sources, and each sound generator is under unilateral, ipsilateral neural control. Different songbird species vary in their use of bilateral or unilateral phonation (lateralized sound production) and rapid switching between left and...
متن کاملBengalese finches Lonchura Striata domestica depend upon auditory feedback for the maintenance of adult song.
Male birds of age-limited song-learning species develop their full song repertoires in the first year of life. For this type of song learner, once song is stabilized in adulthood, it is highly stereotyped and stable over time. Traditionally, it has been believed that age-limited song learners do not depend on auditory feedback for the maintenance of adult song. A recent report, however, showed ...
