The crane is mentioned in the Navis, Yeshayahu and Yermiyahu.
Most owls see well in poor light, but all see well in bright daylight. The owl's eyes are almost immovable, and the owl must rotate its head to look around; however some species can move their heads horizontally 3/4 of a circle, and some can even turn their heads completely upside down.
The soft feathers help them surprise their prey, by providing an almost noiseless flight.
The owl is mentioned in Vayikra as one of the birds that is not kosher and may not be eaten.
Herons are large, long-necked, birds with long legs. They are colored in simple patterns of gray, blue, brown, and white. Frequently found at lakes and marshes, they feed on frogs, fish, and other such prey. They wade slowly in shallow water and when the prey is sighted, the heron pushes its head forward quickly, grasps the prey in its long straight jaws and swallows it whole. Heron nests are built high in trees on platforms of sticks.
Sparrows are typically 3 to 9.4 inches long and are colored brown, gray, white, or pale yellow, with cone-shaped bills. They feed mostly on seeds which they unearth by scratching away the ground litter with both feet, while doing a backward jump. They weave domed nests.
Among young deer the first set of antlers are usually short spikes. As the deer matures, the antlers acquire more sharp points as they become longer. Deer have long, slim legs, each with two toes tipped by strong, curved hooves. Two upper toes, called dewclaws, do not touch the ground as the deer passes, however their prints can be seen in snow.
The color of deer range from whitish gold through different shades of brown, to nearly black. Some also have white spots. Deer are ruminants, with a stomach that has four chambers. Deer are quick runners and swimmers, who can run as fast as 40 miles per hour. Although, when frightened, a deer may remain still, waiting for the danger to pass.
Deer feed on grass, tree bark, leaves, twigs, and sprouts. Unless killed by hunters, predators, disease, or hunger, a wild deer maylive up to 20 years.
Elephants drink by sucking water into their trunks and then squirting it into their mouths. Their fan-shaped ears are up to 5 feet long. African elephants have ivory tusks, which are exceptionally long cutting teeth, one on either side of the upper jaw. Elephants eat only plant material, consuming as much as 500 pounds per day.
Ivory tusks were brought from Ophir for Shlomo Hamelech (King Solomon), from which he made his throne, overlaying it with gold. Elephants were first introduced to Eretz Yisroel at the time the Greeks fought to capture Judea. They were used for military transport. Tragically, Eleazar the Hasmonean was crushed to death under one of these elephants.
The leopard is mentioned in the nevuah (prophecy) of Yirmiyahu to Bnei Yisroel when he states, "Just as the leopard cannot change its spots, so too have you become so habitual in your evil that it is very difficult for you to change."
The species inhabits woodlands and feeds on grasses, ferns, tree bark, and leaves.
The first mention of a ram presents itself at Akeidat Yitchak, as Avraham Avinu binds Yitchak on the altar to sacrifice him to G-d. As he prepares to sacrifice Yitzchak he is distracted by a ram in the bushes. G-d tells Avraham that in the merit of Avraham's absolute commitment to Him, He will forgive the sins of his children, the Bnei Yisroel, when they blow the shofar on Rosh Hashana. Then he commanded Avraham to sacrifice the ram on the altar, in place of Yitchak.
The ram was among the korbanot (sacrifices) brought in the Beit Hamikdash, as well.
