Four-years of monitoring a breeding colony of black-necked stilt ( Himantopus mexicanus ) on the Rio Grande do Norte State coast, Brazil

摘要

The black-necked stilt (Himantopus mexicanus Statius Müller, 1776) is the widest distributed Recurvirostridae species of the Americas, with resident and wintering populations in many wetlands. Researches on behavior, population ecology and threats of this shorebird species have focused on Northern Hemisphere populations, and comparatively little about these topics is known of its southernmost populations (Robinson et al., 1999). In 2013, we registered and described the first breeding colony of black-necked stilt in northeastern Brazil, in a non-natural saline area of the Apodi-Mossoró River Estuary (AMRE), Rio Grande do Norte State (Lunardi et al., 2015). In the current study, we presented data of a four-years (2012-2016) of monitoring the site used as breeding colony to provide additional information regarding seasonality and breeding success of the species in the northeastern Brazil.
