Well the Jersey Devil should be fun. Size and description varies more than the Chupacabra. Here's a nice sample:
"I looked out upon the Delaware and saw flying diagonally across what appeared to be a large crane, but which was emitting a glow like a fire-fly. Its head resembled that of a ram, with curled horns, and its long thick neck was thrust forward in flight. It had long thin wings and short legs, the front legs shorter than the hind."
It was three feet high... long black hair over its entire body, arms and hands like a monkey, face like a dog, split hooves [...] and a tail a foot long
In general appearance it resembled a kangaroo... It has a long neck and from what glimpse I got of its head its features are hideous. It has wings of a fairly good size and of course in the darkness looked black. Its legs are long and somewhat slender and were held in just such a position as a swan's when it is flying...It looked to be about four feet high
"As nearly as I can describe the terror, it had the head of a horse, the wings of a bat and a tail like a rat's, only longer
“about three and a half feet high, with a face like a collie and a head like a horse. It had a long neck, wings about two feet long and its back legs were like those of a crane and it had horse’s hooves. It walked on its back legs and held up two short front legs with paws on them
He described it as being about six-feet tall with horns and matted black fur. Could this have been the reported Jersey Devil - or some other creature altogether? Irwin stated that he and the creature stared at one another for several minutes before the monster finally turned and ran into
room erupted with screams as the child grew at an enormous rate, becoming taller than a man and changing into a beast which resembled a dragon, with a head like a horse, a snake-like body and bat's wings.
As soon as it was full-grown, the monster began beating all the woman (including his mother) with its thick, forked tail. With a harsh cry, it flew through the chimney and vanished into the storm.
Mr. Evans gave the following account: "It was about three feet and a half high, with a head like a collie dog and a face like a horse. It had a long neck, wings about two feet long, and its back legs were like those of a crane, and it had horse's hooves. It walked on its back legs and held up two short front legs with paws on them. It didn't use the front legs at all while we were watching. My wife and I were scared, I tell you, but I managed to open the window and say, 'Shoo!' and it turned around, barked at me, and flew away".
The Jersey Devil of lore does not look like anything humanoid. It is a creature with the head of a horse, large wings and claws, and has a roughly four-foot-long serpentine body. When a person sees the Devil, he or she sees an omen of disaster to come. According to early legends, its appearances have come before
While the descriptions vary, several factors remain fairly constant. It is commonly described as having a long neck, with wings and hooves. It is often said to have a horse-like head and a tail. The height of the creature varies among sightings from about three feet to more than seven feet. Most sightings also report that the creature has glowing bright red eyes and emits a high, human-like scream
its also been described as a 7 foot tall hairy man
Despite being an outsider (?) it apparently requires food but doesnt age. It apparently moves faster than possible for an animal and despite its slight size is strong enough to shake cars and fight rooms full of people. Seems immune to the problems of being exposed to the elements. Jersey Devil

This is one of the cryptid versions of the Jersey Devil. The one most commonly described as hooved and winged with a vaguely horselike head and a thin tail. Combat
: The Jersey Devil only attacks small prey unless provoked. Even then it often simply attacks once before flying away.
