Breeding biology of rainbow bee-eaters ( Merops ornatus ): a migratory, colonial, cooperative bird
The breeding biology of Rainbow Bee-eaters (Merops ornatus) was studied between 1997 and 2001 in southeast Queensland, Australia. Rainbow Bee-eaters are unusual in that they combine migration and coloniality with cooperative breeding. Birds migrate from islands north of Australia to build nests eith...

The breeding biology of Rainbow Bee-eaters (Merops ornatus) was studied between 1997 and 2001 in southeast Queensland, Australia.
