About the Sick's Swift
Sick's swift is a species of swift in the family Apodidae. It was previously considered conspecific with the smaller ashy-tailed swift, but a study published in 1997 found that Sick's swift was closer to the chimney swift. The English name commemorates the German-born ornithologist Helmut Sick who studied South American birds. It is a migratory species that breeds in central South America and overwinters in northern South America. The IUCN has listed it as being of "Least Concern".
