Rookeries

The results will be important for wildlife managers as they consider strategies to lower incubation temperatures at key rookeries around the world.

In otariid species like the South American and Australian sea lions, non-territorial subadults form "gangs" and cause chaos within the breeding rookeries to increase their chances of mating with females.

Mating may occur outside the rookeries, between non-territorial males and females, as the latter move to and from the mating site.

Oliver Twist finishes in the slums and rookeries along its south bank.

Similar to modern pinnipeds, Pteranodon may have competed to establish territory on rocky, offshore rookeries, with the largest, and largest-crested, males gaining the most territory and having more success mating with females.

Their rookeries populate with newborn pups as well as male and female otariids that remain to defend their territories.

The rookeries Pribylov visited held upwards of four million seals, for which they became famous.
