Burhinus bistriatus

Burhinus bistriatus: Suárez 2020 a: 7 [Cuba]. History. — November 1980: S. L. Olson identifies fossils of Burhinus at CZACC and OA (Olson & Hilgartner 1982: 33). 1982: first published notice (5 August) as to presence in Cuban collections of fossil material referable to Burhinus (Olson & Hilgartner 1982: 33). Reported as ‘ Burhinus sp. ’ by Acevedo-González & Arredondo (1982: table 1) without indicating specimens or locality. May 1984: fossils in OA (see ‘ Referred material’) recorded as ‘ Burhinus sp. ’ (Arredondo 1984: 16 – 17). December 2000: first record from asphalt deposits at Las Breas de San Felipe (Iturralde-Vinent et al. 2000: table 2). 22 May 2020: some Cuban specimens identified as ‘ Burhinus bistriatus ’ (Suárez 2020 a: 7).

Double-striped Thick-knee (Búcaro)

Distribution. — Cave and asphalt deposits in west Cuba (see Appendix). Artemisa. Caimito: ACP (Arredondo 1984: 16 [‘ Burhinus sp. ’], Arredondo & Arredondo 2002 a: table 1 [‘ Burhinus sp. ’], 2002 b: table 1 [‘ Burhinus sp. ’]), ASA (Suárez 2000 b: table 1 [‘ Burhinus sp. ’], Arredondo & Arredondo 2002 a: table 1 [‘ Burhinus sp. ’]). Mayabeque. San José de las Lajas: YCC (Jiménez & Orihuela 2021: 169). Matanzas. Martí: MLB (Iturralde-Vinent et al. 2000: table 2 [‘ Burhinus sp. ’], Suárez 2020 a: 7). Direct 14 C dating. — None in Cuba. For dating of other bird species at MLB, see Antigone cubensis, Gymnogyps varonai and Ornimegalonyx oteroi, and of associated extinct mammals (Parocnus browni = 11,880 ± 420 to 4,960 ± 280 years 14 C BP), see Jull et al. (2004) and Steadman et al. (2005). For dating of Burhinus material from the Bahamas, see Jones O’Day (2002). Notes. — Common in Pleistocene deposits, considered a palaeo-ecological indicator of arid open habitat (Feduccia 1980, Pregill & Olson 1981, Iturralde-Vinent et al. 2000). Some material referred to Burhinus from Cuba is of a different size (Suárez 2020 a; WS & S. L. Olson unpubl.), and perhaps involves the smaller B. nanus Brodkorb, 1959, described from the Bahamas and considered a species, or a subspecies of B. bistriatus by some authors (see Olson & Hilgartner 1982: 33, Oswald & Steadman 2018: 363). B. bistriatus still inhabits the Greater Antilles, with the endemic B. b. dominicensis (Cory, 1883) resident on Hispaniola (AOU 1998, Raffaele et al. 1998, 2003, Keith et al. 2003, Latta et al. 2006).

Referred material. — Humerus: right lacking distal end, MNHNCu 75.4783; distal end of right, MNHNCu 75.4792; distal ends of left, OA 2958, and right, OA 2959. Tibiotarsus: distal end of right, MNHNCu 75.4798. See Arredondo (1984: 16), Suárez (2020 a: 7).
