Sources of inter- and intra-individual variation in basal metabolic rate in the zebra finch, Taeniopygia guttata
We investigated the physiological background to individual variation in basal metabolic rate (BMR) in a laboratory population of a small passerine bird, the Zebra finch, Taeniopygia guttata. We especially explored whether food-quality during early development influenced the BMRlater in life. Zebra finches were raised on two different food regimes; one (dlow qualityT) involvingonly mixed...
متن کاملGaze Strategy in the Free Flying Zebra Finch (Taeniopygia guttata)
Fast moving animals depend on cues derived from the optic flow on their retina. Optic flow from translational locomotion includes information about the three-dimensional composition of the environment, while optic flow experienced during a rotational self motion does not. Thus, a saccadic gaze strategy that segregates rotations from translational movements during locomotion will facilitate extr...
متن کاملLong-term repeatability makes basal metabolic rate a likely heritable trait in the zebra finch Taeniopygia guttata.
Basal metabolic rate (BMR) is a physiological trait believed to show adaptational changes. Few studies have tested whether BMR shows stable between-individual variations. Repeatability indicates that the trait might be heritable and therefore a possible target for natural selection. We tested whether BMR was repeatable over a considerable time of the lifespan of a small passerine bird: the zebr...
متن کاملTimbre control in zebra finch (Taeniopygia guttata) song syllables.
Zebra finch (Taeniopygia guttata) song syllables often include harmonically related frequency components. These harmonics may be suppressed, and this differential emphasis varies between the syllables in a song and between individual birds' songs. These patterns of harmonic suppression are timbre. Individual syllables' patterns of harmonic suppression are constant with adult males' songs. Young...
متن کاملSyllable chunking in zebra finch (Taeniopygia guttata) song.
We examined how 61 young zebra finch (Taeniopygia guttata) males copied song from 5 adult tutors. Zebra finch song consists of a string of 5-15 distinct syllables, and these syllables were copied as chunks, or strings of consecutive syllables (modal length = 3). The silent interval between 2 syllables was copied as part of the syllable after the silence. Copied chunks had boundaries that fell a...
