Harris hawks hunt cooperatively in their family group or cast and are remarkable and spectacular to watch. These 'wolves of the sky' work together, either diving from the air or running on the ground to flush prey out of vegetation. They take it in turns to do this until the prey is tired enough to be caught easily.
The chestnut shoulders glow stunningly in the sun, but it's the tail feathers that are used in their silent communication. The white band across the bottom of the tail is visible from a distance and the hawks flick the tail as a signal that everyone is in position and ready to hunt.
When they aren't hunting, they spend most of their time perching or resting in their home range, with females perching higher than the males to show dominance. Here there was enough room for all of them to perch, but when there isn't, Harris hawks do something called back-stacking. They sit on top of each other, up to four birds high, with the dominant bird on the bottom. How I wish II'd seen them doing that!
