Critically Endangered
Alagoas antwren
Myrmotherula snowi
Alagoas antwren is a perching bird in the family Thamnophilidae (order Passeriformes) — Myrmotherula snowi, recorded as Critically Endangered.
Appearance
Adult males are almost entirely gray, with lighter underparts than upperparts. Their throat feathers have black bases and gray tips. Adult females are mostly rufous-brown with darker wing coverts and paler cheeks and throat.
The Alagoas antwren is 9.5 to 10.5 cm (3.7 to 4.1 in) long and weighs about 8 to 11.5 g (0.28 to 0.41 oz).
Range and habitat
Even so, by about 2020 it could again be found only at Murici. It inhabits isolated fragments of semi-humid lowland evergreen forest and is known only from the narrow elevational range of 430 to 790 m (1,400 to 2,600 ft). "No doubt the distribution was much more widespread and continuous, before most forests in this region were cleared".

Diet and breeding
The Alagoas antwren's diet has not been detailed but is known to include insects. It usually forages in pairs and as part of a mixed-species feeding flock.
Prior to 2021 the Alagoas antwren's breeding biology was essentially unknown. The researchers who determined that it was a species collected a female with an egg in its oviduct in February and noted juveniles with their probable parents in May.
