ADAM MITCHELL DOMINICAN RACERS A Predation Attempt Gone Awry: Defensive Constriction of a Predator by a Dominican Racer Alsophis antillensis is a diurnally active snake found on the islands of Guadeloupe, Monserrat, and Dominica in the Lesser Antilles. The subspecies A. antillensis sibonius is found on Dominica, the most southerly of the three islands, where it is widely distributed, particularly in dry forests on the leeward slopes and coast (Malhotra and Thorpe 1999). Buteo platypterus (Broad Winged Hawk) is a small (ca. 34–45 cm tall), forest-dwelling hawk found throughout eastern North America, northern South America, and the Caribbean Adam Mitchell 1 and Lyndon Prince 2 IGUANA • VOLUME 15, NUMBER 3 • SEPTEMBER 2008 155 1 24 London Road, Widley, Portsmouth, Hampshire, U.K., PO7 5BS (adammitchell23@hotmail.com) 2 Salisbury Village, Commonwealth of Dominica, West Indies Basin, where it feeds on a wide variety of small vertebrates (BirdLife International 2004). While radio-tracking Iguana delicatissima on Dominica in June 2008, we encountered a B. platypterus struggling on the forest floor in the Batali River Valley. Upon closer inspection, we discovered a large A. antillensis sibonius defensively constricting the bird’s neck, right leg, and right wing. After several minutes of watching, the hawk’s struggles became weaker and it could no longer stand. In an attempt to observe the head of the snake, A large Alsophis antillensis sibonius defensively constricting the neck, right leg, and right wing of a young Broad Winged Hawk (Buteo platypterus).
