ALAOGAS FOLIAGE-GLEANER AND CRYPTIC TREEHUNTER

Alaogas foliage-gleaners and cryptic treehunters were songbirds found in the dense forests of northeastern Brazil, reported Mclendon and also Drew Macfarlane in a 2019 article for The Weather Channel. Foliage-gleaners were discovered in 1975 but it took scientists decades to discern that cryptic treehunters were a species of their own.

When deforestation occurred across Brazil as forests were replaced by plantations and pastures, many unique birds lost their home, to be placed in the “Critically Endangered” category, according to a 2018 article by Patrick Barkham published in The Guardian.

According to the International Union for Conservation of Nature (IUCN), cryptic treehunters were last seen in 2007 and foliage-gleaners in 2011. They were declared extinct in September 2018.
