No. Hawks are diurnal - they hunt during the day and sleep at night. Their hunting depends entirely on sharp eyesight, which does not function well in low light. Night hunting belongs to owls, not hawks.
Hawks vs Owls - Day and Night Hunters
| Feature | Hawks (diurnal) | Owls (nocturnal) |
|---|---|---|
| Active period | Daytime, sometimes dusk | Night, sometimes dawn |
| Primary sense | Vision | Hearing + vision |
| Eye structure | Excellent daylight vision, poor in darkness | Huge eyes adapted for low light |
| Hunting style | Spot prey from height, dive or pursue | Silent flight, locate prey by sound |
| Typical prey | Rodents, birds, rabbits | Rodents, small mammals, birds |
When Hawks Actually Hunt
| Time | Hunting activity |
|---|---|
| Dawn | Peak hunting time - prey is active and visible |
| Morning | Active hunting continues |
| Midday | Soaring on thermals, scanning for prey |
| Afternoon | Active hunting |
| Dusk | Some species (especially Red-tailed Hawks) hunt at last light |
| Night | No hunting - hawks roost in trees |
Why Red-tailed Hawks Hunt at Dusk
Red-tailed Hawks are sometimes seen hunting in the last hour before dark. This is not true night hunting - they are taking advantage of the “dusk window” when nocturnal prey like mice and voles start emerging but there is still enough light to see. Once full darkness falls, they stop.
The Common Nighthawk Is Not a Hawk
Despite its name, the Common Nighthawk is not a hawk at all. It is a nightjar - a completely different family of birds. Nighthawks catch flying insects at dusk and dawn. The name is a misnomer that causes confusion.
How Hawks Find Prey
| Sense | How hawks use it |
|---|---|
| Vision | 8 times sharper than human eyesight, spot prey from over 1 km |
| Hearing | Secondary sense, used to detect movement in grass |
| UV vision | Some hawks can see rodent urine trails that glow in UV light |
How Often Hawks Eat
| Factor | Details |
|---|---|
| Meals per day | 1-3 depending on prey size |
| Daily food intake | About 12-15% of body weight |
| Hunting success rate | Roughly 1 in 5 attempts succeeds |
| Fasting tolerance | Can survive several days without food |
Do Hawks Hunt in Groups?
Almost all hawks hunt alone. The one notable exception is the Harris’s Hawk, which hunts cooperatively in packs of 2-6 birds in the deserts of the American Southwest. One bird flushes prey from cover while others wait to intercept. This is one of the only examples of cooperative hunting in any raptor.
Are Hawks Dangerous to Pets?
Small pets left outdoors can be at risk. Hawks - especially Red-tailed Hawks and Cooper’s Hawks - will target small dogs, cats, chickens, and rabbits if they are left unattended in open areas. Keep small pets supervised and provide overhead cover.
Hawks are daytime hunters that depend on extraordinary eyesight. If you see a large bird hunting after dark, it is almost certainly an owl, not a hawk. The two fill the same ecological role - one by day, one by night.
