Yellow-headed Caracara on Capivara [1]

an UCI compliant chess engine by Lourenço Araujo de Oliveira Junior, written in C++. Starting with TSCP [2], Lourenço changed and further implemented new methods in evaluation and search, and Tom's simple chess program evolved to a new chess engine which plays with a lot of courage, called Capivara [3]. Capivara LK, with Tom Kerrigan mentioned as co-author, played the CCT13, Capivara the CCT15 with 3/6 [4]. Capivara's opening book is based on Harry Schnapp's HS-Classic Book [5].
