DID YOU KNOW:  Red-shouldered Hawk’s eyes change color as they age. They have yellow eyes when they are young, and brown eyes as adults. Red-shouldered hawks will often use the same nest year after year. The male and the female will work together to build or renovate the nest.   The Red-shouldered Hawk is a member of the genus Buteo, a group of medium-sized raptors with robust bodies and broad wings. Members of this genus are known as buzzards in Europe, but hawks in North America. The Red-shouldered Hawk gets its name from reddish brown feathers on their upper wings giving the bird the appearance of having red shoulders, although this part of the wing is actually the hawk’s wrist.

 WHY DO BIRDS….SUDDENLY APPEAR

The backyard during the day can range in noise.  At any point you either hear the rustling of the leaves or a combination with the bird calls. There are countless of varieties of birds, and some are more prevalent during the different seasons, but some of the regulars include ibis, blue jays, cardinals, herons, red-winged blackbirds, cranes, water turkeys, finches, hawks, pigeons, eagles, sparrows, woodpeckers and vultures. Unfortunately, you also get the rumbling sounds of airplanes and helicopters, but those kinds of birds, I can do without.

DID YOU KNOW: A bird’s heart beats 400 times per minute while resting and up to 1000 beats per minute while flying. Birds have many more vertebrae in the neck than humans, ranging from about 14 or 15 and up to a maximum of 25 in the swan. Humans only have 7!.  All birds are much more mobile than in mammals, which is why most birds can turn their heads 180 degrees. (source: King and McLelland, Birds: Their Structure and Function)
