CARDENAS, Wilian N  and  HURTADO, Liz B. Variation of abundance and diversity of birds in Lucre- Huacarpay Wetland, Quispicanchi / Cusco / Peru, during the period of "El Niño" 2015 - 2016. Ecol. apl. [online]. 2019, vol.18, n.2, pp.111-114. ISSN 1726-2216.  http://dx.doi.org/10.21704/rea.v18i2.1330.

From September 2015 to August 2016, a monthly evaluation was carried out in the six lakes that are part of Lucre Huacarpay wetland (Quispicanchi / Cusco / Perú) aiming to analyze temporal and spatial variation in the abundance and diversity of birds. For this period, 84 species of birds have been registered,included in 14 orders, 29 families, and 67 genres. Regarding the degree of residence, 63 were residents, 4 were temporary, 5 were occasional and 12 were migratory. The lake with the highest species richness and highest values of alfa index diversity was Waskar. The months with the highest species richness were September 2015 and February 2016, with 57 species in each one. The Chao-2 estimator indicates that 84.2% of the total species likely to occur in the area during the evaluation period was registered. The analysis of variance of the Shannon-Wiener diversity index and Tukey-b test among the lakes indicate that Unkapampa has the lowest alfa diversity and differs from the others. The five species with the highest abundance were Zonotrichia capensis (10.34%), Chroicocephalus serranus (9.47%), Fulica ardesiaca (8.23%), Catamenia analis (6.27%) and Gallinula galeata (5.92%).
