Homing pigeons use olfactory cues for navigation in england
Although the use of olfactory cues in pigeon navigation is well established, the generality of olfactory navigation remains uncertain because of apparent variability in results gained by different researchers in different regions. We report the results of the first experiments investigating the effect of anosmia on homing pigeons reared in a previously uninvestigated region, southern England. I...
متن کاملLeft-hemispheric superiority for visuospatial orientation in homing pigeons.
To test for lateralisation of visuospatial orientation during homing, pigeons who had binocularly learned the homeward route from remote release sites were tested monocularly on either their left or their right eye for homing performance. In two experiments with three different release sites, birds using their right eye showed considerably better homing performance. If sun compass information w...
متن کاملMagnetic Fields and the Orientation of Homing Pigeons under Sun
Applying a magnetic field of o-1 Gs (1 gauss = io~*T) to the heads of pigeons homing from unfamiliar release sites significantly increased the scatter of the birds' vanishing bearings. A magnetic field of 0-3 gauss caused no difference between the orientation of birds wearing coils with either their north or south pole up. But a field of o-6 gauss (equal to that of the Earth) produced a small d...
متن کاملHoming Pigeons Respond to Time-Compensated Solar Cues Even in Sight of the Loft
The sun has long been thought to guide bird navigation as the second step in a two-stage process, in which determining position using a map is followed by course setting using a compass, both over unfamiliar and familiar terrain. The animal's endogenous clock time-compensates the solar compass for the sun's apparent movement throughout the day, and this allows predictable deflections in orienta...
متن کاملSun-compass orientation in homing pigeons: compensation for different rates of change in azimuth?
Birds using their sun compass must compensate for the apparent movement of the sun with the help of their internal clock. The movement of the sun is not uniform, being much faster around noon than near sunrise and sunset. If the sun-compass mechanisms are not adjusted to these variations, considerable errors might arise. To learn whether birds are able to take the different rates of sun azimuth...
