Was watching a vet show this a.m., and they said they were treating a goshawk. But the bird in question had partial webbing (not full) between toes,which made me curious. Still have not found such a thing, but figured it might be good to compile what I did find to identify some of our birds' nemesis'. (Mb Oz has webbed hawks?

)
Is it a hawk or a Falcon?
Hawks have sleek,pointed heads,smooth beaks which curve slightly, brown cheeks,stocky, medium-sized bodies,long tails & broad wings w/fingers-like tapering on the ends.The mature hawk has brown stripes on its belly with a white band at the base. They kill w/their talons.
Falcons are smaller & slender, short rounded heads w/ white cheeks and angular beaks w/a bend or notch used for neck breaking. They have tapered wings w/pointed tips.Mature Falcon have striped bellies all the way down, but the juvenile will always have the white cheeks.
Which kind of Hawk?
There are 16 species of hawk in the US. I'm just hitting on the more common ones, as some avoid civilization or have limited range in US.
Red-tailed Hawk
Since the red tailed hawk can be difference colors, it's identifying attribute is the red tail. It's usually seen more in the winter but can be found pretty much anywhere in North America but breed in Canada summers. They don't hang out at bird feeders but will go for your poultry. They are said to mate for life & reuse nests every year when possible.
I don't tend to get close enough to see tail color, but if we hear this,
That's a red-tailed hawk. (Numi & the pup are NOT impressed)
Length: 18-26 inches / 45-65 cm
Weight: 1.5-3.5 lbs. / 700-1600 gm
Wingspan: 43-55 inches/ 110-140 cm
Scientific Name: Buteo jamaicensis
Sharp-shinned Hawk or Cooper's Hawk?
Smallest hawk in US, fast moving,upper chest has orange bars that fades downward, wings & back are blue-gray. Their wings are short and rounded, tail long. An ambush predator, they are often found near bird feeders. They are often confused w/the Cooper' s hawk, though 6" shorter & 1/2 the weight.
Coop has a cap and flaps wings slowly
Sharpie has a cape and flaps quickly.
The link I share at bottom has their sound imbedded sharpie is high pitched kikikikik,cooper is cakcakcak. I bet when you hear you'll recognize both.
Northern Goshawk
A Cooper's hawk is often mistook for a goshawk. They're similar, & goshawks don't like being around us. But goshawks have dark heads and red eyes, bluish white to gray barred under-bellies and blue-gray to brown upper bodies. They are larger and fiercer than the above birds & will attack.
Red-shouldered Hawk
Barred red chest, white underwings,banded tail, red shoulders visible when perched. Mainly in North-South Central, Mid-South Atlantic regions. The hunting style makes them unique as they drop from directly above.
(now all 3 dogs on alert)
