Icteridae

Dolichonyx oryzivorus (MGT) : breeds in North America from May to July and flies non-stop in August through the sea of the Antilles and the coast of Venezuela. In Florida these birds converge into large flocks until they reach their wintering areas in eastern Bolivia, southern central Brazil, Paraguay and northern Argentina, covering 20,000 km in this round trip. Its main wintering site is the Pampas from southeastern South America ( Di Giácomo & Krapovickas, 2005; Azpiroz et al., 2012). This species reaches the Pantanal in MT in Brazil in November, and then northeastern Bolivia, Paraguay and the Pampas in Argentina, after crossing the entire Amazonian region ( Sick, 1983, 1997; Fraga & Christie, 2016). Three individuals were recorded for Cachoeira de Nazaré/RO in November while flying across the Amazon ( Stotz et al., 1992). Geolocation data from 15 individuals captured in three different breeding areas in the USA suggested that fall migration occurs through the Caribbean with a stopover in northern Venezuela, and another in Bolivia in November. 12 individuals flew to a region in Argentina between December and March, where they molted completely before the spring return migration ( Renfrew et al., 2013). Records for RS were made in December ( Belton, 1985) and sound records for MT in November, while photographic records for MS were between November and March. For SP there is only one record in January (WikiAves, 2016). Museum records are restricted to AM in April (MPEG).
