Myrmoderus ruficaudus soror (Pinto, 1940) ,

Scalloped Antbird (IUCN and MMA: EN)

This species is represented in the PCE by the endemic subspecies M. r. soror , which is confined to humid forests in the states of Paraíba, Pernambuco and Alagoas ( Zimmer & Isler, 2003; Grantsau, 2010). This taxon is known in the PCE from 29 localities (Farias et al., 2002; Roda, 2003; Silveira et al., 2003a; Farias et al., 2007, 2010) and currently persists in forest fragments of varying sizes and in varying states of degradation. We recorded this species from an additional four sites in Pernambuco ( Table 2).

Terenura sicki Teixeira & Gonzaga, 1983 , Orange-bellied Antwren (IUCN and MMA: EN)

Roda et al. (2011) reported this PCE endemic in 14 forest fragments in upland forest (between 300 and 700 m asl) in the states of Pernambuco and Alagoas. Albano (2009) also reported this species in lowland forest (c. 80 m asl) at Usina Trapiche. We add two new localities in Pernambuco ( Table 2, Fig. 7 ). This species is typically seen accompanying mixed-species flocks: at the Parque Natural Municipal Mucuri-Himalaya it was observed foraging with Veniliornis sp. , Sittasomus griseicapillus , Herpsilochmus atricapillus , Phylloscartes ceciliae, Basileuterus culicivorus and Lanio cristatus , and at the Engenho Brejão was observed in a mixed species flock including Myrmotherula axillaris , Herpsilochmus atricapillus and Phylloscartes ceciliae . This species is still recorded with some frequency at the Mata do Estado and Engenho Água Azul (GAP), and six territories were located at the 630 ha RPPN Frei Caneca in November 2012 (ACL: WA#814109, XC#113530; November/2012). It has apparently declined to a handful of pairs (perhaps now a single pair) at the ESEC Murici, Alagoas ( Albano 2009, A. Whittaker pers. comm.). The causes of this nearextinction at the latter site are unknown, but given that the ESEC Murici is the largest remaining forest patchin the PCE this is a very worrying trend, and we consider that this species now qualifies for Critically Endangered status based on a total population now estimated at fewer than 250 mature individuals in a few disparate forest fragments.

Xipholena atropurpurea (Wied, 1820) , White-winged Cotinga (IUCN and MMA: EN)

Restricted to primary lowland and adjacent foothill Atlantic forest (up to 900 m asl), between Paraíba and Rio de Janeiro ( Snow, 2004), it has been reported from 13 protected areas ( BirdLife International, 2013). This species has been recorded from 25 localities in the PCE between 1961 and 2003 (Roda, 2003). Our fieldwork produced records from an additional four sites in Pernambuco ( Table 2, Fig. 8).
