Whooping Crane Family--Part V

Wetland Buffet. Considered omnivores, whooping cranes spend most of their time walking and foraging for food. While many of the foods they eat are found in wetland areas, they also eat seeds, berries, grains and nuts found in fields, prairies, savannas and uplands.
Whooping crane parents bring their chick a variety of foods to teach him what to eat and provide the nourishment he needs for rapid growth.At ICF's Amoco Whooping Crane Exhibit, I watched as the male presented the chick with a food item, such as this whole crayfish, then dropped it to the ground and broke it into smaller pieces before offering it to him to eat.


A tadpole?The offering below appears to be a minnow. (You have to look closely.)

The chick above is two days old. While most young birds must mature rapidly in order to fledge in time for migration, the whooping crane chick has a long way to grow, from four inches to the nearly five feet he achieves before fledging.Here you see the same chick at four weeks (above and below).

And below, you see the chick at eight weeks. Photo by Sara Zimorski, aviculturists at ICF.
A young whooping crane chick may grow an average of one inch per day and be ready to fledge sometime between 78-90 days of age. Migration begins mid to late October for most whooping cranes. The juveniles below were photographed in late September and each practice flight increases their strength, endurance and skill at coordinating their seven-foot wing span.

Aren't they amazing?!
And just three months ago, they looked like this...

This year's fledgling class of re-introduced whooping cranes are scheduled to begin their ultralight-led migration on Oct 17, weather permitting. To read the daily progress of these young whooping cranes who will fly from Wisconsin to Florida on their first migration, visit Operation Migration's field journal. Youth and teachers will also enjoy Journey North's informative pages and updates on the migration.

Whooping Crane Family--Part IV

In the first days of its life, a whooping crane chick quickly attaches to and follows his parents through an instinct called imprinting. But following is an effort that takes practice.
A lot of stumbling takes place until the chick develops strength and awareness of both his body and his environment. And the parents do their best to help.

While they are watching out for the chick, foraging and bringing him food, they spread their toes and use their feet to flatten the grasses around the chick's path. ICF biologists at the exhibit speculated that this grass-pressing behavior helps the parents keep up with the chick in the tall grass and enables them to better see predators. It also enables the chick to move about more freely.

Brian Johns, Whooping Crane Coordinator for the Candian Wildlife Services confirmed for me that this behavior is also observed in the wild. Wild birds build a platform for their nest in the water so that the chick can get out of the water but still be away from the shore and predators. But since the wild birds are constantly on the move there is also no extensive grass pressing or platform building in any one area.
As you can see in the chick video posted on October 7, within a couple of days the chick has gained strength and coordination and follows his parents with more ease...

and is even running...and flapping his wings!

Whooping Crane Family-Part III on Video!

My friend, Jeff Huxman, videographer and co-founder of SolTerra Communications, caught this amazing video footage of the whooping crane family and has allowed me to post it here for you. Shortly after the video begins you will hear a 'guard call' or alert. Then watch what happens!

Whooping Crane Family--Part II

A whooping crane chick's day. I witnessed this peaceful scene between the chick and its mother on the chick's second day as they rested near the water's edge.
There was a constant communication between the parents and the chick, reassuring even to me as I observed. The brood call is a purring sound, deep, gutteral and constant, with the male's tone slightly deeper than the female's. The chick answers with tiny peeps and these soothing sounds assure the family that all is peaceful and safe in their world. The whooping crane is a prey species, ever vigilant for dangers and intruders. The parents working as a team, watch over their chick, in this case, the male hunting in the water, the female staying near the chick and almost exclusively presenting him with insects she catches nearby.Above, the chick has wandered back to the nest, a mass of plucked grasses which are now darkened by decay. As he rests, the female brings him an insect she has clasped in her bill. (The precision of these catches never ceases to fascinate me.)Below the male is hunting for crusteceans and tadpoles in the water. The disarray of feathers you see are molted feathers that have not fallen off yet. The whooping crane's appearance is usually sleek with its feathers neatly preened.

The chick's chief activities include sleeping, eating and learning what to eat and how to be a crane as it exercises and grows stronger.
The chick is moving past the male as he tries to present a morsel of food.

Though he appears to be, the chick isn't exactly following the female above, either. He is exploring and learning to use his legs. She watches over him carefully, even while hunting, and shifts directions to stay near him.
Oops....
Time to rest a while.

With the exception of group tours that came through the observation area periodically, for much of the day I was alone in this exhibit wetland with the cranes and their chick. The silence gave me plenty of opportunity to forget there was another world. What I mostly heard was the vocalizations of the whooping cranes, the rippling of water, the buzz of insects and the beeping of a few swallows over head. This world that I glimpsed, at its best, was an incredibly peaceful world.

Whooping Crane Family--Part I

It was this series of sandhill crane notecard images that prompted me to ask the question, "Is there any place on earth I could view and photograph a whooping crane caring for its chick?"I was speaking to George Archibald, co-founder of the International Crane Foundation (ICF), during a quiet moment at a wildlife exhibit in the spring of 2004. So many times, while expressing delight over this card collection, now sold out, customers asked me, "do you have any whooping crane images like these?"
I expected George's answer to be one of amusement. The original wild population of endangered migrating whooping cranes, numbering approximately 307 today, nests in Wood Buffalo in the Northwest Territory of Canada. Their nesting sites are inaccessible except to authorized biologists who monitor their numbers. Because this population was reduced to only 15 birds in the early 40's, genetic diversity is of up-most importance to the survival of the species. Captive-reared birds are carefully monitored for genetic value to the wild population and decisions about each off-spring are made by an international recovery team.
To my surprise, he responded by saying there was a good possibility that the whooping crane pair at the Amoco Whooping Crane Exhibit at ICF might be allowed to raise their own chick within full view of the public. And so it was that this door of opportunity opened.It was in June of the next year, 2005, that I received the call, "we're putting a pipping egg in the nest tonight and it should be hatched by morning." With that, I dropped everything and began the twelve hour drive from Knoxville, TN to Baraboo, WI, arriving around eleven a.m. June 19.

The sleeping chick had hatched in the pre-dawn hours. When it awoke and raised it's head, two very attentive parents greeted it with food.The image above is among my favorite photos because it captures the parents' earnest attentiveness. As the chick stirred, they moved in unison, almost as one, carefully offering the chick the tiniest of insects held in their enormous bills.The chick toppled over on his face, so new was he to life that when he reached for the morsels he lost his balance. The parents retracted their bills, waited for him to erect himself, then ever so slowly, moved their bills toward him again to offer the food.

Keep in mind that an adult whooping crane is five ft tall and its newly hatched chick measures only about four inches, not even the size of the adult's head and bill combined...
and you get a glimpse of how truely awe inspiring it was to witness the patience and gentleness demonstrated by these two parents. Next: A whooping crane chick's day.
