Natural history and conservation of the endemic avifauna in north-west Peru

  • Theodore A. Parker III (a1), Thomas S. Schulenberg (a2), Michael Kessler (a3) and Walter H. Wust (a4)
Summary

Roughly 30% of the avifauna of the dry tropical forests of north-western Peru and adjacent south-western Ecuador is endemic to this small region. Large areas in this region, especially on the Ecuadorian side of the border, have been deforested, further heightening the threatened conservation status of this fauna. The largest remaining tracts of forest in this region are in the Bosque Nacional de Tumbes, Peru. This forest, which was visited in 1986 and 1988, holds significant populations of 12 threatened or near-threatened species, and smaller populations of at least three more endangered species. Six species (Aramides axillaris, Thalurania colombica, Picumnus olivaceus, Attila torridus, Arremonops conirostris, Carduelis siemiradzkii) are reported in Peru for the first time. Evidence is presented for seasonal movements of some species, including the threatened Leptotila ochraceiventris and in the small Peruvian population of Pionus chalcopterus. Based primarily on vocal evidence, it is proposed that Thamnophilus zarumae and Grallaria watkinsi be recognized as full species, and that “Empidonax” griseipectus be transferred to Lathrotriccus; further work is needed on the species status of endemic forms in other polytypic species such as Sittasomus griseicapillus and Pyriglena leuconota.

Aproximadamente 30% de la avifauna de los bosques secos tropicales del noroeste del Perú, y del suroeste de Ecuador, es endémica a esta pequeña región. Extensas areas en esta región, especialmente del lado de la frontera ecuatoriana, han sido deforestadas, aumentando así la amenaza para la conservación de la fauna. Los más grandes vestigios de bosque seco tropical que subsisten en esta región están localizados en el Bosque Nacional de Tumbes en el Perú. Este bosque, que fue visitado en 1986 y 1988, tiene poblaciones significativas de 12 especies amenazadas o con posible amenaza de extinción, y poblaciones pequeñas de 3 especies más que están en peligro de desaparecer. Notas sobre la historia natural son presentadas para 28 especies, incluyendo 11 especies que están amenazadas o en peligro de extinción. Seis especies (Aramides axillaris, Thalurania colombica, Picumnus olivaceus, Attila torridus, Arremonops conirostris, Carduelis siemiradzkii) están reportados en el Perú por primera vez. Evidencia es presentada para movimientos estacionales de algunas especies, incluyendo la amenazada Leptotila ochraceiventris y la población pequeña peruana de Pionus chalcopterus. Basandose principalmente en evidencia vocal, se propone que Thamnophilus zarumae y Grallaria watkinsi pueden ser reconocidas como especies y que “Empidonax” griseipectus puede ser transferido a Lathrotriccus. Se necesita más estudios para determinar el estatus de las formas endémicas de especies politípicas como Sittasomus griseicapillus y Pyriglena leuconota.
