Abstract The White-collared Kite (Leptodon forbesi) is an endemic and threatened raptor of the Brazilian Atlantic Forest. Here we present the known records of the species, describe the vegetation types where it was found and show Ecological Niche Models generated using Maxent algorithm. Most of the presence data were recorded in open ombrophilous forest and seasonal semideciduous forest in the states of Alagoas and Pernambuco. Maxent model had a good performance (AUC = 0.982 ± 0.004 SD), showing higher suitability for the species from Paraíba to Alagoas states. Maxent average model revealed a distribution range of 20,344 km² and an area of occupancy of 1,636.89 km². The most suitable areas for the species are those near watercourses and streams. We suggest...

Status of the globally threatened forest birds of northeast Brazil Pap. Avulsos de Zool. (São Paulo)

The Atlantic Forest of northeast Brazil hosts a unique biota which is among the most threatened in the Neotropics. Near-total conversion of forest habitat to sugar cane monocultures has left the region's endemic forest-dependent avifauna marooned in a few highly-fragmented and degraded forest remnants. Here we summarise the current status of 16 globally threatened species based on surveys conducted over the last 11 years. We found a bleak situation for most of these species and consider that three endemics: Glaucidium mooreorum (Pernambuco Pygmy-owl), Cichlocolaptes mazarbarnetti (Cryptic Treehunter) and Philydor novaesi (Alagoas Foliage-gleaner) are most likely globally extinct. Some positive news can, however, be reported for both Leptodon forbesi...
