To examine how high workload affects haematology, oxidative stress and reproductive output, we experimentally manipulated foraging effort in captive zebra finches, Taeniopygia guttata , using a previously described technique, and allowed individuals to breed first in low...

... expenditure is due to the existence of an energetic ceiling and/or compensation by males during parental care. To investigate whether an energetic ceiling exists, we experimentally manipulated foraging effort in captive zebra finches, Taeniopygia guttata , creating two groups with high and low foraging...

... in order to match the memorised vocalisations. Here, we investigated auditory perception of self and others in zebra finches ( Taeniopygia guttata ), a highly gregarious songbird species and vocal learner. We used laboratory colonies in which founder males had been previously trained to produce the same...

...Nicole Geberzahn; Sébastien Derégnaucourt ABSTRACT Many species are able to vocally recognize individual conspecifics and this capacity seems widespread in oscine songbirds. The exact acoustic features used for such recognition are often not clear. In the zebra finch ( Taeniopygia guttata...

... investigated the effects of daily food availability times on reproductive performance and quality of eggs and offspring survivors in zebra finches ( Taeniopygia guttata ). In randomly paired birds kept under a 12 h:12 h light:dark cycle for about 52 weeks, food availability period was restricted to 4 h...

In each individual, CORT and MR were measured at two different temperature levels: ‘warm’ (22°C) and ‘cold’ (12°C). CORT and MR were both increased in colder compared...

Nevertheless, the physiological mechanisms that allow some individuals to support higher foraging performance, and the mechanisms underlying costs of high workload, remain poorly understood. We experimentally manipulated foraging behaviour in zebra finches ( Taeniopygia guttata...

We conducted a 2×2 factorial design experiment in captive adult male and female zebra finches ( Taeniopygia guttata ) to determine the effects of carotenoid supplementation...

We measured kinematics using high-speed video, aerodynamics using particle image velocimetry, and ground-reaction forces using a perch mounted on a force plate. In contrast with the first three wingbeats of take-off...

Using incubating male and female zebra finches ( Taeniopygia guttata ), a species in which the male lacks a brood patch, we measured the surface temperature of the ventral plumage overlying the abdomen and a reference area that does not contact the eggs (thorax) twice per pair.

To investigate this transition, we integrated measurements of both leg and wing forces during take-off and the first three wingbeats in zebra finch ( Taeniopygia guttata , body mass 15 g, N =7) and diamond dove ( Geopelia cuneata , body mass 50 g, N =3).
