Species Distribution and Climate Change

Abstract: We surveyed the montane forest bird community at 18001900 m elevation in western Sierra de Neiba, Dominican Republic during 68 February 2003. We documented a total of 36 species, of which 18 were recorded on point counts and 12 were captured in mist-nets. Observational data revealed that canopyforaging species were lower in abundance than during our previous visit to the site in November of 1997. We captured 57 individuals in 361.5 net-hours (15.8 birds/100 net-hours). The most abundant species in our mistnet samples were Eastern Chat-Tanager (Calyptophilus frugivorus; n = 10), Green-tailed Warbler (Microligea palustris; n = 9), and Rufous-collared Sparrow (Zonotrichia capensis; n = 8). Noteworthy records included one Antillean Mango (Anthracothorax dominicus), 11 Caribbean Martins (Progne dominicensis), nine Bicknells Thrushes (Catharus bicknelli), and eight La Selle Thrushes (Turdus swalesi). The broadleaf forest, while recovering from past disturbances, appeared to be little changed from 1997, and we believe that prospects for longterm conservation are moderately encouraging.

Documentamos un total de 36 especies, de cuales 18 estaba recordados en los conteos por puntos y 12 capturados en las redes. Los datos por observacin revalaron que las especias forrajeando en el dosel estaban menos por abundancia que durante nuestra visita al sitio en noviembre de 1997. Capturamos 57 individuos en 361.5 horas de redes (15.8 aves/100 horas de redes). Las especies mas abundantes in nuestras muestras de redes fueron Patico Chirr (Calyptophilus frugivorus; n = 10), Ciguita Colaverde (Microligea palustris; n = 9), y Sigua de Constanza (Zonotrichia capensis; n = 8). Observacines notables incluieron un Zumbador Grande (Anthracothorax dominicus), 11 Golondrinas Grandes (Progne dominicensis), nueve Zorzales Migratorios (Catharus bicknelli), y ocho Zorzales de la Selle (Turdus swalesi). El bosque latifoliado, mientras que recobrando de disturbios pasados, parecieron estar poco diferente de 1997, y creemos que las esperanzas para conservacin a largo plazo estan moderadamente alentandas.
