Cacicus haemorrhous

The collection of seven red-rumped caciques between 1951 and 1952 (MZUSP 37684-37690; Pinto,1954),and another eleven in 1957 (MZUSP 39265-39269; LACM 27141, 27142, 27164-27167), at the coastal forests of Alagoas suggest that the species was once common in the state. It was also collected in nearby Pernambuco in 1880(NHMUK 1885.11.2.114 and 1885.11.2.115; W. Forbes), 1903 (NHMUK 1903.12.15.62 and 1903.12.15.63; A. Robert) and 1927 (AMNH 245727, 245728, 245748-245751; E. Kaempfer). Although the species was once common in the PCE ( Teixeira, 1992), it has currently been recorded only in the vicinity of the Murici Ecological Station (e.g., WA 4222775;C.Almeida) and may be close to local extinction.
