Like a little child, the hawk would be fast asleep after driving just a mile or two at night. But when I stopped at a stop light and some trucker looked down into my car, the presentation was a bit eerie. I merely waved and moved on. That bird caused a lot of late night scratched heads. Red-tails, like most other birds, have an interesting and useful foot locking mechanism used when sleeping.
As the bird begins to nod off, there is a ratchet-like band of tissue that can be tightened around the inside of the leg. The hawk doesn't have to pay any attention to holding on during the night. I think in those situations the bird must both lock its toes around the branch, and also stay awake and lean over into the wind.
I don't know this, either, but I presume that the birds in these situations will attempt to park themselves in a somewhat protected position in the tree or woodlot.
And this is why it would be so good to put a radio transmitter on a wild red-tail and find out just where the bird sleeps each night. What about heavy rains? This is exactly why red-tails spend so much of their time diligently preening their feathers.
As with all birds, they have the oil gland on their rump. The lean over and strop their bill on this gland, pick up some feather oil, and then preen it into all the feathers on the body. Still, in the heaviest down pour, the outer feathers can get soaked.
But the fluffy, inner down feathers remain oiled and water repellent. After a summer rainstorm we often seen a sodden red-tail. Red-tails, like all birds, are like turtles. They carry their houses of feathers with them wherever they go. And except for the incubating mother, the parent hawks do not sleep in or on the nest.
Yes, the birds stay near the nest, and often sleep within a hundred yards or so of it. One other thing that was wonderfully discovered with Pale Male in NYC was that when he took his night perch, sometimes at some distance from the nest, he always seemed to maintain a straight, clear visual path to the nest. He could see the nest from where he slept. Even in thick branches there seemed to be always a clear view of the nest.
That, then, raises the question of how well the hawks can see at night. From watching my several falconry red-tails over the years, it seems pretty evident to me that they can see at night just about as well as I can. But I have some evidence that red-tails may be able, like rattlesnakes, see a bit down into the infrared spectrum.
For red-tails, this nighttime vision is still a bit sketchy and conjectural. Unknown June 28, at PM. Anonymous November 11, at PM. Anonymous February 16, at PM.

Those that live in northern areas move south for the wintertime. Those that live in milder climates stay put. When red-tailed hawks sleep, they do so in high trees, often close to the trunks.
They're frequently drawn to trees that have thick leaves and branches, particularly in times of aggressive winds and cold. When it comes to setting up nests, red-tailed hawks tend to prefer the outer portions of forested areas. Many of them also put nests together within sizable trees, as long as the trees are surrounded by lots of free space.
When determining nesting spots, height is a major consideration. Red-tailed hawks feel comfortable when they can easily observe -- from above -- all of the things going on around them in their environments.
Apart from trees, it's not uncommon for red-tailed hawks to use cliffs for nesting. Some even nest in the windows of buildings and residences. They build their nests using components such as dry plants, leaves, sticks and pieces of tree bark. If you're trying to spot a red-tailed hawk around you, look higher.
These birds are usually on the lookout for food while in the midst of flight or simply hanging out on utility poles. Nocturnal birds, like owls and nighthawks, wake up as the sun sets and hunt at night.
During the daytime, they find a safe place and close their eyes to block out the light. These species will find something to perch on, like a branch or a windowsill, for the night. Then, the bird will fluff out its down feathers, turn its head around, tuck its beak into its back feathers, and pull one leg up to its belly before falling asleep. Sounds uncomfortable, right? Down feathers, the short fluffy feathers under the sleek outer ones, hold in heat.
The bare parts of the bird the beak and the legs are tucked in to keep warm under the thick blanket of feathers as temperatures drop for the night. Actually, it is very unlikely that roosting birds will fall from their perch. When the bird places weight on its feet, the muscles in the leg force the tendons of the feet to tighten, keeping the foot closed.
