Hawks and Eagles (Accipitridae)

Mangrove Black Hawk (Buteogallus subtilis) - HBW 2, p. 173

French: Buse des mangroves German: Mangrovebussard Spanish: Busardo negro del Pacífico
Other common names: Pacific Black Hawk

Taxonomy: Urubitinga subtilis Thayer and Bangs, 1905, Gorgona Island, Colombia.
Taxonomic status remains uncertain: until recently considered a race of B. anthracinus, but elevated to specific level based on apparent lack of hybridization with anthracinus; however, there may be contact in Panama where the forms are practically indistinguishable, making detection of hybridization very difficult. Forms superspecies with B. anthracinus. Three subspecies normally recognized.
