THE MISSISSIPPI SANDHILL CRANE

The Mississippi sandhill crane is a slate gray bird with white face markings and a red crown. Four feet tall, this sub-species of the non-migratory Florida sandhill crane is smaller and darker in color than its Florida cousin. The only remaining population of Mississippis lives year round on a refuge named for it. The Mississippi Sandhill Crane National Wildlife Refuge is located on three separate tracts of land along the Gulf Coast, in Gautier, Mississippi. In the past, sandhill cranes existed in small separate colonies all along the Gulf Coast of Louisiana, Mississippi, Alabama, and Florida. Now there are two separate populations. The Florida sandhill is found only in Florida, and the Mississippi sandhill only exists in one small area of Mississippi.

In the 60's, only 30 Mississippi sandhills were left. Eggs taken from this remnant flock were brought to the Patuxent Wildlife Research Center and eventually became a successful breeding flock. Birds raised at Patuxent were sent to the Refuge for release. Today, there are around 120 cranes on the refuge, almost 3/4 of the flock captive-reared. The first costume-reared birds at Patuxent were Mississippis, and it was the survival success of these human-reared birds that gave scientists hope that whooper chicks could be reared the same way and survive in the wild. The Mississippi sandhill crane program at Patuxent became the prototype for the whooper release program.

Whoopers and Mississippis are very different cranes, with different behavior and environmental needs. However, rearing techniques first used in the Mississippi program have successfully been incorporated into the whooper release program. The released whoopers have had high survival, and the successful hatching and rearing of whooper chicks in Florida from parent birds which were costume-reared is proof that costume-rearing can be used to establish cranes back into the wild.

Mississippi sandhill cranes are still very endangered. The refuge is located on land which has been used for decades for pine tree plantations. Since the habitat originally was wetland and savanna, habitat restoration on the refuge is an important part of their land management. Removing trees, filling in drainage ditches, doing controlled burns, and allowing the land to restore itself to its natural state will take years. The refuge has been suffering an historic drought, as Florida has, and this has had a severe impact on the cranes, reducing chick production drastically. Also, predators such as bobcats and coyotes, are an on-going problem.

While Patuxent no longer produces Mississippi sandhill cranes, focusing now on whoopers, captive reared Mississippi cranes from both the White Oak Conservation Center in Jacksonville Florida, and from the Audubon Institute are sent to the refuge every year to bolster the population until it can become self-sustaining.

Cool Facts:



Newly Hatched Mississippi Sandhill Crane Chick on Nest

Newly Hatched Mississippi on the Nest, USFWS Photo

Mississippi chicks and whooper chicks look similar. But to people who work with them, the differences are obvious. Mississippi chicks and whooper chicks look similar. But to people who work with them, the differences are obvious. Mississippi chicks are 20-50 grams lighter, hatching at 100 grams as opposed to the whoopers' 140 grams. The Mississippi chick is lighter in color than the whooper, with pink legs. Their eyes seem larger, and their bills smaller. The whooper is usually dark with dense down and dark legs. Since they come from different environments, this makes sense: the whoopers need thick down to survive in their northern breeding range, while the Mississippis' native home along the Gulf coast is much warmer.

Before any research can be done on whooping cranes, it is first tried on non-endangered sandhill cranes such as Florida sandhill cranes or Greater sandhill cranes. Once the research seems safe with a good chance at success, only then is it done on whoopers.  Before any research can be done on whooping cranes, it is first tried on non-endangered sandhill cranes such as Florida sandhill cranes or Greater sandhill cranes.

When Mississippi sandhills were at Patuxent, these rare birds were given the same concerned care. Breeding and release programs were tried out on Florida and Greater sandhills before begun on the Mississippis. Success with these programs was a promising prediction for similar work with whoopers.  When Mississippi sandhills were at Patuxent, these rare birds were given the same concerned care.
