If you're referring to "maintaining the breed" while breeding, they use the breed standard and a very carefully thought out selection of the breeding pair and of their breeding program.
An "Alpha pair" is the dominant breeding pair in a pack of animals. This is usually a normality in wolf packs. Only the alpha female and alpha male are allowed to have offspring.
Penguins form monogamous pairs for each breeding season. The rate the same pair recouples varies drastically.
Breeding structures among nonhuman primates vary a great deal between species. However, monogamous pairs are not seen often. Some family groups may start with a monogamous pair, but this arrangement usually drops quickly when other members are added to the family.
No they don't because I think it is extinct
You can, but it really depends on the personality of the breeding pair. Sometimes, the breeding pair will be so territorial that they will not breed with other cockatiels in close proximity, and will toss the eggs out of the nesting box. Others have no problems at all, and several pairs of cockatiels will be breeding at the same time. It is important to make sure the aviary is large enough to accommodate more birds, and that each of the breeding pairs has sufficianet privacy, for example, placing nesting boxes at opposite ends of the cage.
NO
I have seen estimates upwards of $80,000 for a pair of breeding hyacinth macaws, banded as bred in captivity, in the USA. They are highly endangered in the wild and are not the best of breeders in captivity. They are very large birds who need large flight cages. They are very intelligent birds and need a great amount of care when they are babies, and the care is longer than most all other birds. Properly weaned and trained, it can take a year to raise one baby hyacinth macaw.
