Due to having very broad and large wings, the Black-collared Hawk often soars while hunting for food. Once they have obtained a target, they swoop down and pluck it from the water with their long curved talons. They they proceed to take their catch to an out-cropping or branch and eat while they sun-bathe and dry.
Black-collared Hawks are not known to be territorial unless they have a nest to protect their young.
Not socially monogamous, the Black-collared Hawk reselects their mate every year, but generally reuses their previous nest for a few seasons.
Social and interspecific behavior
Black- Collared Hawks, when alone, tend to spend their time closer to the groung unless they are hunting. This makes them easy to observe, but also makes it less likely to see more than one at a time.
The Black-collared Hawk regularly preys on fish, snakes, small water-going mammals, frogs, snails, and turtles, but will generally capture whatever it can if it is near the water.
