Glaucidium mooreorum da Silva, Coelho & Pedreira

Pernambuco Pygmy Owl (Glaucidium mooreorum)

The Pernambuco Pygmy Owl was described in 2002, it is/was restricted to the state of Pernambuco in eastern Brazil.

The species was restricted to an extremely small range when it was described, and the population was estimated to count only about 50 birds or perhaps even less.

***

The Pernambuco Pygmy Owl is now considered extinct, since the only known habitat of the species is now nearly completely destroyed. [1]

The photo below shows a related taxon, the Ferruginous Pygmy Owl (Glaucidium brasilianum (Gmelin)), a species that occurs also in Pernambuco, Brazil.

Cichlocolaptes mazarbarnetti Mazar Barnett & Buzzetti

Cryptic Treehunter (Cichlocolaptes mazarbarnetti)

The Cryptic Treehunter is an enigmatic species that is currently included in this genus following thorough morphometric analyses, however, it differs strikingly from the other two species in this genus and superficially resembles the Alagoas Foliage-Gleaner (Phylidor novaesi Teixeira & Gonzaga) with which it occurred sympatrically.

***

The Cryptic Treehunter was restricted to two localities in the states of Alagoas and Pernambuco, Brazil, where it inhabited the last surviving remnants of the former rainforest.

The species reached a size of about 21 cm. 

The Cryptic Treehunter was described in 2014, just seven years after it was last seen, the species is now considered most likely extinct.

Vriesea rectifolia Rauh

Erect-leaved Vriesea (Vriesea rectifolia)

The Erect-leaved Vriesia was described in 1984, it was found near the town of Correntes in the state of Pernambuco, eastern Brazil.

The species morphologically resembles Lubbers’ Vriesea (Vriesea lubbersii (Baker) E. Morren) from  southeastern Brazil but differs from that species by its inflorescence with flowering branches and other characters. 

The species was never found again in its type locality but was kept in a botanical garden for a while, where it flowered and died without leaving descendants.

Thus, the Erect-leaved Vriesea is now considered extinct. [1]
