Kinglet Calyptura (Calyptura cristata) is one of the greatest enigmas of the South American avifauna. A tyrannid that looks like a kinglet, the species is endemic to a small area of south-east Brazil in the Atlantic Forest biome. The species was first described by Vieillot in 1818 and conventional wisdom suggests that it went unobserved between at least c.1890 and 1996, when it was briefly rediscovered in submontane forest above Rio de Janeiro (Pacheco and da Fonseca, 2001). Since then, C. cristata has been reported several times, but without documentation and always by single observers. It is currently considered Critically Endangered by BirdLife International and various authors have speculated that the species might already be extinct. In this webinar, Guy Kirwan describes his painstaking museum research for Kinglet Calyptura, which included more than 100 specimens, mostly in European collections, almost doubling previous estimates made in the literature. Several are held in relatively small institutions, thereby suggesting that yet more specimens might still be identified. From analysis of this large sample of material, Guy discusses the morphology of the kinglet.
with what evidence do you make such a baseless claim? Do you perhaps subscribe to an outdated taxonomy that relies solely on morphology?@@Manumanunitomidri

I hope this page stays up forever, or at least for a very long time. I was able to learn quite a bit from it. Thank you to all involved.

TYRANIDAE..???? Calyptura cristata is a Cotingidae.....the same family of Bell Birds.....Procnias...and etc.....
