5. Herons: Some heron species, such as the great blue heron, are known for flying at low altitudes, especially when hunting for fish.
6. Vultures: Vultures are large birds of prey that scavenge on carcasses. They often soar at low altitudes in search of food.
7. Grouse: Grouse are game birds that prefer to stay close to the ground. They often fly short distances, flushing up from the underbrush.
8. Hummingbirds: Hummingbirds are tiny birds that rely on nectar and insects as food sources. They can often be seen hovering at low levels near flowers and other sources of sustenance.
9. Owls: Some owl species, such as the short-eared owl, hunt for small rodents and insects by flying close to the ground.
10. Kites: Certain species of kites, like the Mississippi kite, exhibit low-flying behavior while searching for prey.
Please note that this list is not exhaustive, and there are many other species of birds that engage in low-flying behavior.
