Apodidae

[ Cypseloides niger ] (MGT): breeds in North America and migrates south, sometimes in large flocks, and groups of 300 to 400 individuals have already been recorded in California ( Chantler, 1999). Geolocation data showed that the fall migration of C. n. borealis started between September 10 th and 19 th, that it reached the wintering grounds in Western Amazonia (especially in AM) between September 28 th and October 12 th, and that it departed from these grounds heading to the breeding sites between May and June ( Beason et al., 2012). This is the first piece of evidence of wintering grounds for this species in Brazil, which is why it is considered migratory.

Chaetura meridionalis (MGT) : breeds in Bolivia, Brazil, Paraguay and Argentina, and migrates to Panama, northern Colombia, Venezuela, Suriname and French Guiana during winter. It reaches its breeding site in early September, where it remains until mid-April ( Chantler, 1999; del Hoyo et al., 2016b). It breeds in SP in September-March and departs from Atlantic Forest lowlands in southeastern SP in April-August ( Aleixo & Galetti, 1997). It also can be seen in RJ, breeding between late August and early September; it departs in March/April. It nests in MT in October and November ( Sick, 1997) and it is considered a migrant in RS ( Accordi & Hartz, 2013), where there are records of breeding activity from November to January ( Belton, 1984). Photographic records suggest breeding activity in CE, BA, MG, RJ, SP, PR, SC and RS between October and January (WikiAves, 2016). Occurrence records are centered in the period of September to April (WikiAves, 2016; MNRJ; MZUSP; MPEG).
