Little-known species : the Black-collared swallow

[vogelcommando]

Intresting article about this critically endangered species :

Range and conservation of the regionally Critically Endangered Black-collared Swallow, Pygochelidon melanoleuca (Wied, 1820) (Aves, Hirundinidae), in Minas Gerais, Brazil

Checked IUCN, it says it's Least Concern. Now I've confused myself.

 

[Swampy]

I think they're saying it's Critically Endangered in Minas Gerais, not overall.

 

[Chlidonias]

yes, the paper actually says in its second paragraph that the species is Least Concern globally, Near Threatened in Brazil, and Critically Endangered in the Brazilian state of Minas Gerais.
