Apparently, the species name rutila means “red, golden red, reddish yellow”, which sounds a bit like a contradiction in itself. It is well known that chicks of this morph immediately start having an identity crisis when combining the knowledge of their species name with the information gathered from a look in the mirror.

BirdLife International believes that this might be maximum population the species can reach, as it seems to completely saturate its range. Also from BirdLife International: In general it prefers areas where vegetation, boulders or other landscape features at ground level provide tunnels in which to shelter and to breed.

More than 50 years ago, the Hawaiian Goose (Nene) was one of the first birds listed under the Endangered Species Act, part of the inaugural “ Class of 1967 ”. Under the Endangered Species Act, any listing, uplisting, downlisting, or removal from a list requires a formal “rulemaking” process.

Drakensberg (or Orange-breasted) Rockjumper is a Drakensberg Mountain species whose range is shared with the tiny landlocked kingdom of Lesotho. Males of this species are more brightly colored in their non-breeding winter plumage. the Rockjumpers.

And much of that time is spend loafing around the breeding colonies trying to pair off and engaging in silly-looking behaviours referred to as dancing by scientists. It can take over a year to raise a chick for the larger species, and even species that can fit their entire breeding cycle into one year tend not to breed in consecutive years.
