Cuculidae

Micrococcyx cinereus (MGT) : occurs in Bolivia, Uruguay, northern Argentina and Brazil and is migratory at the extreme south of its distribution ( Payne,1997), with records for the Brazilian Amazon associated with migrants that originated in the south ( Sick, 1997). It seems that this species breeds in southern and southwestern Brazil and migrates north during winter ( Payne & Bonan, 2013). Records of breeding activity for RS in November, combined with a lack of records for the south during colder months from May to July in SC and RS ( Belton, 1994; WikiAves, 2016), seem to confirm the migratory pattern. In other states – AC, RO, PA, TO, MT, MS, GO, CE, RN, PB, AL, SE, BA and SP – records are scarcely distributed throughout the year ( Lyra-Neves et al., 2012; WikiAves, 2016; MPEG; MZUSP).

Coccyzus melacoryphus (MGT) : occurs from northern South America to Bolivia, Paraguay, Argentina and all of Brazil ( Sick, 1997). There is a lack of data about its migratory pattern, but it seems to be a migrant, especially in the extreme south of its entire distribution ( Payne, 1997). In southern and southeastern Brazil – MG, ES, RJ, SP, PR, SC and RS – photographic and museum records are centered in the period of October and April (MZUSP; MNRJ; MPEG; WikiAves, 2016. However, in northern, northeastern and central-western Brazil, although there are records sparsely all over the year, it seems to be concentrated between January and September (MZUSP; MNRJ; MPEG; WikiAves, 2016. Breeds in BA and RS ( Maurício et al., 2013;WikiAves, 2016.

Coccyzus americanus (MGT) : breeds in North and Central America and flies at night during fall to the Antilles and Bahamas (2,000 -3,000 km) from where it moves south in non-stop flights of over 4,000 km to wintering grounds in South America. Its migration occurs during the night mainly across the ocean, though it also flies over the continent. This species overwinters east of the Andes, from Colombia and Venezuela to Brazil (MT), Uruguay and Argentina ( Payne, 1997), and reaches Brazil during boreal winter ( Sick, 1997).Geolocation data showed that one individual flew around 9,500 km during its migration south through Central America to overwinter in Bolivia, Brazil, Paraguay and Argentina. Its spring flyway went over the Caribbean, which was different from its fall flyway. In addition, it also flew round-trip between New Mexico and Mexico at the end of the summer during both years it was monitored before it was captured at the breeding site ( Sechrist et al., 2012). In Brazil, except for SP where it seems to be recorded all year round ( Crozariol, 2011), its occurrence is limited to November until May in almost all states ( Belton, 1984; Fedrizzi & Carlos, 2011; Melo et al., 2011; Nunes et al., 2011; Vallejos et al., 2011; Vasconcelos et al., 2011; Xavier & Boss, 2011; WikiAves, 2016; MZUSP), which corroborates the presented migratory pattern.
