Crax cf. fasciolata

Independent anecdotal evidence convincingly indicates that a curassow of the genus Crax occurred in the PCE until the 20 th century ( Pinto, 1952; Teixeira et al., 1987; Teixeira, 1992; Lees & Pimm, 2015).The species was painted, supposedly based on birds from the PCE,during the 17 th century in the then Dutch-controlled northeastern Brazil (see Marcgrave, 1648: 195; Teixeira, 2009: 117; reviewed by Teixeira, 1992). Later, oral testimonies from multiple old hunters in coastal Alagoas also indicated the past occurrence of“a curassow other than Pauxi mitu ” ( Pinto, 1952) or“a yellow-billed curassow” ( Teixeira,1992) in the region. Thus, both paintings of birds putatively from the PCE and multiple oral testimonies from hunters suggest the historic existence of a curassow of the genus Crax in the PCE. As speculated by other authors ( Pinto, 1946, 1952; Teixeira, 1992), it is possible that the PCE population of this curassow was related to C. f. pinima from eastern Amazonia. Such a distributional pattern makes sense from a biogeographical perspective because it matches the pattern of other bird lineages with an isolated population in the PCE and a sister population in eastern Amazonia, including Xenops minutus ( Burney, 2009) , Thamnophilus aethiops ( Thom & Aleixo, 2015) , Cercomacroides laeta and Dendrocolaptes medius .
