An annotated avian inventory of the Brazilian state of Alagoas, one of the world’s most threatened avifauna

“…In the meantime, also noteworthy is the long-term work of the ornithologist Anita Studer at the Pedra Talhada Biological Reserve, who has produced valuable information about the avifauna from this important site in the state (e.g., Studer & Vielliard, 1988;Studer et al, 2018). More recent bird collection expeditions carried out in the state include one in Olho d'Água do Casado, led by Galileu Coelho and Mário Ferreira da Silva in 1999, which produced a few hundred specimens now deposited at the FMNH and Universidade Federal de Pernambuco (UFPE), in Recife; one at Engenho Coimbra (Usina Serra Grande), led by the ornithologists Sônia Roda, Marcelo Sousa andJose Tello between 1999 and2000, which also produced a few hundred specimens deposited at the FMNH and UFPE; another at the same site by the Museu Paraense Emílio Goeldi (MPEG) in June 2010, which produced about seventy specimens; and several expeditions to multiple forest fragments (e.g., Mata do Cedro, Fazenda Santa Justina, Usina Coruripe, Usina Santo Antônio, Usina Sumaúma and Usina Serra Grande) led by LFS between 1999 and 2020, which produced hundreds of specimens deposited at the MZUSP.…”

“…The great morphological similarity of this species and the more widespread Chopi Blackbird Gnorimopsar chopi has been a source of confusion and misidentified re-cords since its discovery (Short & Parkes, 1979;Studer & Vielliard, 1988;Collar et al, 1992). The Forbes's Blackbird was long known only from the holotype in the British Museum at Tring, until Short & Parkes (1979) discovered several misidentified museum specimens of the species.…”

“…Many flocks, identified as being of this species, were observed in the municipalities of Quebrangulo and Porto de Pedras between 1987and 1988(Teixeira et al, 1989. On the one hand, documented records in northern Bahia (e.g., WA 4346261; P.E.…”

“…Specimens from these 1951-1958 expeditions yielded an unprecedented increase in the state's bird list and revealed several new bird taxa endemic to the PCE (Pinto, 1952(Pinto, , 1954Pinto & Camargo, 1961), starting a prolific period of ornithological surveying in the state. Between 1979 and1988, the Brazilian ornithologist Dante Teixeira led several surveys in Alagoas, especially in areas near the municipality of Murici, which revealed four bird species new to science (Teixeira & Gonzaga, 1983a, b, 1985Teixeira, 1987) and several range extensions (Teixeira et al, 1986(Teixeira et al, , 1987(Teixeira et al, , 1988(Teixeira et al, , 1989(Teixeira et al, , 1993. The region of Murici then attracted the attention of many ornithologists and birdwatchers that carried out field work in the region in the 1990s and early 2000s and produced several remarkable records (e.g., 2021).…”

Invasive birds: global trends and impacts

“…Two of these species are threatened globally: the Bahamas Oriole (critically endangered) and Yellow-shouldered Blackbird (endangered) (IUCN, 2018). In addition, according to the IUCN (2018), other globally threatened species within the native distribution of Shiny Cowbirds are also negatively affected, such as the endangered Pale-headed Brush-finch (Atlapetes pallidiceps; Krabbe et al, 2011), Forbes's Blackbird (Anumara (= Curaeus) forbesi; Studer and Vielliard, 1988), Apolinar's Wren (Cistothorus apollinari; Villaneda-Rey and Rosselli, 2011) and the Yellow Cardinal (Gubernatrix cristata; Dominguez et al, 2015), and the vulnerable Saffron-cowled Blackbird (Xanthopsar flavus; Fraga et al, 1998), the Pampas Meadowlark (Leistes (= Sturnella) defilippi; Azpiroz, 2015) and the Black-and-white Monjita (Xolmis dominicanus; Azpiroz, 2015).…”
