Distribuição temporal de aves aquáticas em Campo Grande, com ênfase no Lago do Amor (UFMS), usando dados de ciência-cidadã

Abstract

Waterbirds are those considered dependent on the resources provided by wetland areas (nesting, breeding, feeding, and others). Wetlands play an important role in maintaining various species of waterbirds, each with a distinct mosaic and distribution in relation to biotic and abiotic factors. The migration and movements of waterbirds are related to various factors (competition, food availability), and this monitoring can provide an understanding about their functions, mainly through citizen science platforms like WikiAves. The objective of this study was to analyze the occurrence and distribution of waterbirds in Lago do Amor and other locations in Campo Grande using WikiAves records. To do this, bird species classified as aquatic or water dependent according to Stotz et al. (1996) and Sick (1997) were considered, and their records were counted through searches on WikiAves for the municipality of Campo Grande. For Lago do Amor, only records specified by users in the captions were considered. Eighty species of waterbirds were recorded, of which 41 (51%) were seen in Lago do Amor. Thirty-two species had more than 30 independent records, and their seasonal distribution was analyzed. The most recorded species for Campo Grande was the Southern Lapwing (101 observations), and for Lago do Amor the Capped Heron (3 observations). It was found that all aquatic bird species had fewer records during the winter and dry months, with few specific observations for Lago do Amor. The wetlands of Campo Grande are important areas for the waterbird community, suggesting the need for regular monitoring of the seasonal variations in abundance (especially for migratory species), combined with improvements in search tools for WikiAves, which provide important databases on these issues.
