Most of the Osprey breeding in North America are migratory, only Florida, the Caribbean and Baja California host non-migratory breeders 1. In migratory populations males usually arrive to breeding grounds a few days before the females and look for nest sites.

Most Acorn Woodpeckers are cooperative breeders and live in family groups of up to a dozen or more individuals. Within a group, 1–7 male co-breeders compete for matings with 1–3 joint-nesting females who lay their eggs in the same nest cavity. This is their range map courtesy of Nature Serve.

In the mid-1970s, a local breeder was burglarized and a few of his birds escaped, after which the breeder released his remaining stock of about 50 birds 1. Like most dove species, Eurasian Collared-Doves are prolific breeders. In warm climates they can breed year round.

Among birds the Egyptian Vulture uses rocks to crack Ostrich eggs, the New Caledonian Crow and Woodpecker Finch (one of several Darwin Finches of the Galapagos Islands), uses sticks to extract grubs from inside a branch. This is similar to the fact that all birds, even first time breeders within a species build identical nests.

In my imagination, the job of a male Australian Brush Turkey is pretty similar – removing or adding bits and pieces to his pile of rotting vegetation in order to get the right temperature to incubate the eggs buried underneath to hatch. It breeds in tree holes, presumably explaining the more commonly used name for it.
