Juvenile penguins move more than adults do as they change and/or establish breeding locations away from adults (Boersma 1976).
Because of that lag, in a world with a fast-growing population we are just one crop breeding cycle away from starvation.
The summer distribution of the Yellow-billed Cuckoo ranges throughout much of the United States, southeastern Canada, Greater Antilles, and Mexico, but range boundaries have been confused by recurrent observations of nonbreeding individuals away from breeding sites.
Among other things, this work has provided important information on foraging ecology (e.g., Robert and McNeil 1989, Robert et al. 1989), migration (e.g., McNeil and Cadieux 1972), and the role of parasites in causing birds to summer away from breeding grounds (McNeil et al. 1995, 1996).
Females are more likely to be found away from breeding sites, while the opposite applies for males.
Birds which remain in Tasmania move away from breeding areas and are found in paddocks in loose flocks of up to fourteen birds.
If concentration of a historic mutation via inbreeding was the cause of the problem of cryptorchidism on the AP, this would require virtually no movement of breeding animals onto or away from the affected region.
This was the result of a small number of A. forsteri hybrid males holding territories over multiple years as well as a small proportion of females mating away from breeding beaches with pure A. forsteri males [ 25].
Fifth, sometimes corridors can act as attractive sinks that draw individuals away from breeding habitat into dispersal habitat, possibly even slowing down dispersal rates between habitat patches (Ovaskainen et al. 2008).
Experts at Chester have created a purpose-built breeding facility for the newts, away from all other amphibians housed at the zoo to ensure their bio-security.
