The Tiny hawk is a species of small diurnal bird of prey found in or near forests, primarily humid, throughout much of the Neotropics. It is primarily a bird-eater, and is known to prey on hummingbirds. Usually named Accipiter superciliosus, it is the only species of the genus Accipiter yet studied which has a large procoracoid foramen. It also differs from the typical sparrowhawks in other respects of its anatomy and in its DNA sequence. Consequently, its old name Hieraspiza superciliosa may be more appropriate.
