Cypseloides

Rußsegler at the Iguaçu Falls

Cypseloides is one of the least known bird species in the family of sailors ( Apodidae ). The genus includes medium to larger ships, all of which occur exclusively in the Americas. Typical of the genus are the nesting sites, all species breed near water.

Description

All species are medium to dark brown and tend to have in the region of the head on a paler plumage especially on the forehead and chin. Despite the absence of clear plumage characters in most species of this genus, the species can use Cypseloides distinguished by their characteristic shape of other good sailors sympatric species. The tail is relatively short and straight cut, forked at best weak.

Most significantly, perhaps the flight. The wing beats are slower than in the smaller genera, but also do not convey the impression of acting quite relaxed deep wing beats of Streptoprocne species. The flight seems rather unstable, which is perpendicular to the body outstretched wings seem a little stiff and are often directed downward. The Cypseloides species have the maneuverability of the related genera are missing something.

The genus can be assigned the following ways:

• Black Swift ( Cypseloides niger)
• Brustfleck Swift ( Cypseloides lemosi )
• Rothschild Swift ( Cypseloides Rothschildi )
• Smoke bats ( Cypseloides fumigatus )
• Diadem Swift ( Cypseloides cherriei )
• White-chinned Swift ( Cypseloides Cryptus )
• White-fronted Swift ( Cypseloides storeri )
• Rußsegler ( Cypseloides senex )

Sibley & Monroe made ​​two Super Species: niger ( consisting of black sailors, sailors chest patch, Rothschild sailors and sailors smoke ) and Cryptus (consisting of white chin and white sailor sailors forehead ). The tiara sailor and the Rußsegler make this isolated species dar.

The Phelps and Rothalssegler were also formerly attributed to this genus, but are now assigned Streptoprocne because of their plumage and other biological characteristics of the species.
