Maybe you'll be inspired for your own trip! Planning a trip to Florida? How wonderful you were able to keep track of the family even for a short time! The good news is that this story is repeated every year many times over!

What magnificent creatures and what a superb series of photographs! Flight and Function Cranes are opportunistic fliers, relying on thermals and tail winds to carry them along. Thermals are rising columns of warm air and when southerly winds start to blow in late March and early April along the Platte, you will see cranes testing them for flight conditions.

Cranes ride thermals so efficiently that they have been seen flying over Mt. Their bills and feet are important tools. A crane's bill is very sharp and sturdy, useful when probing frozen soil.

The edges are serrated to grasp slippery food like worms and snakes. Not only is it used for preening, it is also used as a weapon. The feet and legs work in conjunction with the beak. The foot has three long toes with claws on the end. These claws are very sharp and can be used for scratching in dirt to find food and for protection. When a crane is threatened, it will use its wings to maintain its balance and then jump up and strike at the attacker with its feet.

How do they do that? Do you ever wonder how cranes stay warm while standing for hours in near-freezing water? They can reduce the amount of blood that has to be warmed by constricting blood vessels in their feet. In some instances, we are not allowed to hatch the eggs of some of our pairs, because those pairs are already well represented in captivity. Q: How many of the chicks at the International Crane Foundation survive to fledge? A: About percent. Q: How big are crane eggs? A: The size of a crane egg depends on the species.

The larger the crane, the larger the egg. The largest of crane eggs is about 4. They are usually tan with brown speckles. Q: If you take eggs, will the cranes lay more? A: Yes. One Sandhill pair once laid 19 eggs in a single season, but we usually want a pair to lay only 5 to 6 eggs so the female is not unduly stressed. Q: Do cranes ever select a mate from another species?

Their offspring are fertile. We do not crossbreed species. A: A male will also incubate the eggs, but his primary task is to maintain the integrity of the territory. Incubating pairs trade places about every two hours during daylight hours. This gives each bird a chance to stretch, exercise and feed. At night, the female incubates while the male stands guard.

The male is often the first to feed the chicks. Q: Cranes mate for life. What happens if one dies? A: If a mate is lost, the remaining bird will usually find another partner. Q: How old are cranes before they mate?

A: It varies, but typically cranes are several years old before they begin breeding. In captivity, about three years old; in the wild, about four to five years old. Siberian Cranes may not breed until they are seven years old. Q: What do you do with crane eggs that are infertile? This makes it a bit more durable than an empty shell. Dummy eggs are used by our Crane Conservation Department to give inexperienced cranes practice incubating.

These eggs are also used by our Conservation Education Department for hands-on learning, or sent out to museums or researchers.

Q: What is the process for moving eggs or birds? A: Eggs are moved in foam-lined, heated boxes. Plastic gloves are worn when eggs are handled to protect the shells from skin oils. Cranes are shipped in specially designed crates that are large enough so the birds can either stand or lie down, but not large enough for them to open their wings. Mated pairs are shipped in larger crates so they are in visual and vocal contact, although separated by a partition.

The size and construction of the crate is important in reducing the possibility of the bird being injured. Q: Do cranes get deer ticks? A: Each October, we conduct an annual health check which includes a check for external parasites such as ticks. We have found few wood ticks on the birds. There are also deer ticks on our site, so remember to do tick checks after walking our trails.

Chick Rearing Techniques Q: What is isolation rearing? A: Chicks raised by isolation rearing are fed by a crane puppet and exercised by an aviculturist disguised as a crane.

The chicks hear only other cranes, either on tape or in a nearby enclosure. These birds may later be introduced to wild flocks of cranes where they learn additional survival skills. Q: Why do you raise cranes in isolation from humans? A: There are two main reasons why we rear chicks in isolation:. Birds for release: Birds raised in isolation from humans are better adapted for living in the wild. Parent-reared birds, chicks raised by adult cranes, may also be released into the wild.

Birds for captivity: Some species are more prone to imprinting on people than others e. Eastern Sarus Cranes. These birds are reared in isolation before being exposed to humans. Exposure to humans is necessary or the chicks may be afraid of people. If afraid, the birds may injure themselves while trying to get away from people.
