Birds Of North America

Governments and conservation groups work to protect Birds, both by passing legal guidelines that preserve and restore fowl habitat or by establishing captive populations for reintroductions. Birds have frequently reached islands that mammals have not; on these islands, birds could fulfil ecological roles typically performed by larger animals. For example, in New Zealand nine species of moa were important browsers, as are the kererū and kokako right now. Today the vegetation of New Zealand retain the defensive variations developed to protect them from the extinct moa.

The chick guard stage describes the interval of breeding throughout which one of the grownup Birds is completely present on the nest after chicks have hatched. The main purpose of the guard stage is to aid offspring to thermoregulate and defend them from predation. Many birds actively defend a territory from others of the identical species in the course of the breeding season; upkeep of territories protects the food supply for their chicks. Species which might be unable to defend feeding territories, such as seabirds and swifts, often breed in colonies as an alternative; this is thought to offer safety from predators. Colonial breeders defend small nesting websites, and competition between and within species for nesting sites could be intense. Homosexual behaviour has been observed in males or females in quite a few species of birds, including copulation, pair-bonding, and joint parenting of chicks.
