Yes, they are active all year long.
Some rural people call all hawks "chicken hawks", under the false notion all hawks prey on poultry. Red tails may occasionally take a chicken, but normally they prefer rodents and snakes. The Cooper's hawk and goshawk, which are Accipiters, or "bird hawks", will take poultry.
Leopards hunt during all seasons.
Very few hawks hunt in groups. Most likely, a "pack" of hawks together are migrating, and all taking advantage of the same air currents. It is also possible for a family - parents and the newly fledged young - to be seen together for a few days. One species of hawk that does hunt in groups is the Harris's hawk, but they rarely soar. See http://en.wikipedia.org/wiki/Harris%27s_Hawk I think it's also likely if you saw a group of "hawks" soaring together that they were actually vultures.
Oh yes. The red tail, red shouldered, Cooper's, sharp shinned, kestrel, and broad winged hawks are all found in Connecticut.
No. Hawks are not omnivores, they are carnivores (they only eat meat).
falcons, hawks, harriers all hunt the lowly rabbit. An eagle may try for a rabbit but they are a bit to bulky to catch the whilley varmat.
Yes hawks do live in WI. The Sharp-shinned Hawk, Cooper's Hawk, Northern Goshawk, Harris Hawk, Red-shouldered, Hawk Broad-winged, Hawk Swainson's, Hawk Red-tailed, Hawk Ferruginnous Hawk Rough-legged Hawk all live in WI.
All animals eat plants at times, but carnivores specifically hunt to consume meat. Examples of carnivores include lions, tigers, and hawks.
no hey are not.
Do you need a deer licence to hunt coyote during a deer season?
no not at all
All hawks, as well as all birds, are vertebrates. That means they have a backbone.
