Breeding pair insect. True breeding pairs are rare in amphibians or reptiles, although the Australian Shingleback is one exception with long-term pair-bonds. Some fish form short term pairs and the French angelfish is thought to pair-bond over a long term. True breeding pairs are quite common in birds. Breeding pair arrangements are rare in mammals, where the prevailing patterns are either that the male and female only meet for copulation (e.g. brown bear) or that dominant males have a harem of females (e.g. walrus). Breeding pair Breeding pair is a pair of animals which cooperate over time to produce offspring with some
Seabird breeding behavior that does not support the inbreeding avoidance hypothesis. Close inbreeding was observed at low frequencies in the Mediterranean Cory’s shearwater ("Calonectris diomedea diomedea") where two mother-son pairs were reported. Chick-rearing is the most crucial stage of the reproductive cycle in determining final reproductive success during a breeding season. Chick-rearing includes brooding, feeding, defending, and in some cases, teaching the chick skills it will need to know to survive independently. Chick-rearing can be totally absent in some birds (the brush-turkeys of southeast Asia), to a couple weeks long in many passerines, to several months long in larger birds. Seabirds, along with
