Filling the distribution gaps of two species of Accipiter Brisson, 1760 (Aves, Accipitriformes) in northeastern Brazil

Abstract

We present new records of Gray-bellied Hawk, Accipiter poliogaster (Temminck, 1824), and Rufous-thighed Hawk, A. striatus erythronemius (Kaup, 1850), from northeastern Brazil and review the occurrence of these species in this region. While A. s. erythronemius occurs in secondary forests in the semi-arid regions of northeast Brazil, A. poliogaster seems to be associated more with mature and wet forests and not in the Caatinga scrub.

A noteworthy new record of Gray-bellied Hawk, Accipiter poliogaster (Temmink, 1824) (Accipitiformes, Accipitridae), in the lowlands of northern Costa Rica

“…in Brazil and from 1,950 m a.s.l. in Ecuador (Howell 2002;de Melo et al 2019). Despite having a wide geographical range, the distribution of A. poliogaster is patchy and occurring only locally, and it is generally rare (Collar 1986).…”

“…Accipiter poliogaster is classified as Near Threatened in Costa Rica (BirdLife International 2022). Additionally, despite its ample distribution, records are scant and localized, and few specimens are preserved in museums (Lanzer et al 2009;de Melo et al 2019).…”
