Abstract

TORRES, Miriam; QUINTEROS, Zulema  and  TAKANO, Fernando. Temporal variation in the abundance and diversity of shorebirds at the Pantanos de Villa Wildlife Refuge, Lima, Peru. Ecol. apl. [online]. 2006, vol.5, n.1-2, pp.119-125. ISSN 1726-2216.

From March 2005 to February 20006, 18 species of shorebirds were recorded at the Pantanos de Villa WildLife Refuge, including both resident and migratory species. During the non- breeding season there were two abundance peaks in September and January, the latter with highest abundance than the former one. Calidris pusilla, Tringa flavipes and Charadrius semipalmatus were species that recorded the highest numbers in January. This suggests that populations of these birds that come from other wetlands will use Pantanos de Villa as a stopover on their migration routes to their breeding places. January also recorded young Himantopus mexicanus, Charadrius vociferus and Haematopus palliates, which increase bird abundance in this month. Diversity results present the highest values in the months that had the highest abundance
