Second, prominent examples of male-mediated gene flow typically involve taxa with long-distance migration and nesting-site fidelity, such as the green sea turtle (Chelonia mydas) that migrates between foraging and nesting locations separated by hundreds to thousands of kilometers [44], [45].
In contrast, Kark and coworkers [ 18] did not find any significant changes in mean relative brain size of species along an urbanization gradient in Jerusalem, but suggested that ability to exploit urban areas depended on a combination of life history traits such as diet, sociality, migration and nest sites.
Barnes's first monograph collects his photographs of dioramas, taxidermy, animal skulls, bird migrations and nests (including "Hooded Oriole," 2000, above).
56%) great tits made their nest box choice before the first collared flycatchers returned from migration and initiated nest building, which demonstrates that they can actively avoid the features apparently preferred by flycatchers in the previous breeding season without flycatchers being present when the choice is made.
The researchers are tracking the turtles' migrations to eventually create "protected swimways" between their feeding and nesting areas.
All of these problems are compounded by the lack of comprehensive data on population size, nesting and foraging sites, migration and mortality.
To understand whether the sense of smell is involved in nest finding at the return from migration and to study the interplay with other positional cues, we explored the homing behaviour and nest choice by Mediterranean storm petrels, Hydrobates pelagicus melitensis.
They argue that wind farms should still be sited away from migration routes in the first place, and that the technology does nothing to solve the problem of installations that disturb bird and animal habitats and nesting grounds.
Special pens and nesting areas were constructed.
All cages contained shelters and nesting material.
