Egg size, offspring sex and hatching asynchrony in zebra finches Taeniopygia guttata
Experimental synchronization of onset of incubation was employed in laboratory held zebra finches Taeniopygia guttata to study whether differential resource allocation and possible bias of offspring sex in subsequent eggs in the laying order could mitigate the effects of hatching asynchrony. We found that egg mass increased with laying order, but offspring sex was not related to laying order. A...
متن کاملFirst Report of Coccidiosis and Gizzard Erosion in a Zebra Finch (Taeniopygia guttata) of Iran
Coccidiosis and gizzard erosion are rare conditions in cage bird. A male zebra finch was presented with a history of watery diarrhea, anorexia, ruffled feathers, weight loss, and lethargy and died finally. Gross necropsy revealed small areas of erosions and hemorrhages on the gizzard wall. The intestine was oedematous. The spleen appeared pale and small. The testes were asymmetric.Histologicall...
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 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 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...
