2018, SPATIAL DISTRIBUTION OF SHOREBIRDS WADERS FOR ELEVEN ZONES DESCRIBED IN THE ARENILLA COASTAL WETLAND - LA PUNTA, CALLAO

The Coastal Wetland "Poza de la Arenilla" (HCPA) located in the district of La Punta (Callao) receives each year a significant group of shorebirds of which no detailed information is available. The present study aims to define the spatial distribution of shorebirds species in the wetland between January 2013 and December 2015 to determine the composition in each of the identified areas. The areas defined for this habitat are: Boulders 1 (CR1), Channel, Chanel wall (MC), Shore, Sandstone shore 1 (OA1), Sandstone, Roquedal 1 (R1), Water mirror 1 (EA1), Roquedal 2 (R2), Water mirror 2 (EA2) and Sandstone shore 2 (OA2). Were recorded 2 species for the family Haematopopidae, 4 for Charadriidae and 13 for Scolopacidae.The species that contributed the most to the habitats and seasons were: Actitis macularius (Linnaeus, 1766), representing the zone Shore (97.59%), and the season spring (27.40%); Charadrius semipalmatus (Bonaparte, 1825), in O.A.1 (36.13%) and summer (25.07%), Arenaria interpres (Linnaeus, 1758), in EA2 (62.81%) and autumn (24.81%). Autumn was the season with the lowest abundance compared to other seasons, this due to not being in the migratory shorebird migration season mostly migrating to the family Charadriidae and Scolopacidae.
