A small, stocky, short-winged hawk
- Bluish-grey head and upperparts
- Pink cere
- White underparts

Humid lowland forests, forest edges and areas of fragmented forests.
They sit quietly in the canopy, waiting for a prey individual (includes a wide range of small vertebrates) to reveal itself, and then darts toward it with lightning speed.
Their diet is not well recorded, but is known to consist of lizards and snakes, and they may also attack other birds at army ant swarms.
They fly fast above or through the canopy.
