The semicollared hawk (Microspizias collaris) is a rare bird of prey species in the family Accipitridae.

In 2021, a phylogenetic study found it and the semicollared hawk to form a distinct group from the rest of Accipiter, that is sister to Kaupifalco.

In addition, some semicollared hawks have been heard singing songs that consist of the repetition of a mid-pitch vvt-vvt sound.

One has been spotted in Otanga, in northwestern Ecuador, at 1,900 m. This is neighboring the Mindo-Tandayapa area, where most other records of semi collared hawks have occurred.

[4] Between 1,300-1,800 m in the humid montane forests in the Andes of Táchira, northwest Barinas, and Mérida, there have only been two claims of spotting this species.

[4] There is very little information on the feeding behavior of the semi-collared hawk, but In northern Colombia, a male was found with passerine feathers in its stomach.

Another semicollared hawk was found chasing Dusky Bush Tanagers at Otanga in the western slopes of the Andes in northwestern Ecuador.
