Several Manatees Swimming Toward Danger and the Oil Spill; Mobile May Release Dammed Waters

Biologists know that a handful of manatees are in the Gulf of Mexico and swimming westward–toward the massive Deepwater Horizon oil spill, but so far they have decided not to try to intervene. Mobile Bay officials may release dammed waters to push the oil away from the bay, a local scientist says.

A female manatee that spends the summer in Mobile Bay is now in Appalachicola Bay, FL, says Ruth H. Carmichael, senior marine scientist at the Dauphin Island Sea Lab, which is bracing for the oil slick.  Appalachicola Bay is roughly 250 miles from Mobile–if you take the shore route. They can swim up to 45 miles a day, but 5-15 is more likely.

“I hope she finds a nice location to wait for a while,” Carmichael says. “The USGS also has a few tagged manatees they know are moving this way.  We are doing nothing to move or disturb the animals.  Right now the oil is offshore and the manatees are in shore.  We need to trust them to take care of themselves for now.”

Manatees spend the winter near hot springs or power plants in Florida, but as their population has recovered, they are swimming further in the summer. A few now regularly visit Alabama and every few years a young male makes it up to New England.  

“Mobile Bay is trying to arrange for discharge of dammed waters , if needed, to force water out of the Bay and keep it westward off shore,”

Groups Recruiting Volunteers to Clean up to 400 Wildlife Species at Risk From Oil Spill

A stunning 400 species of birds, marine mammals, turtles, land mammals and reptiles could be hurt by the Deepwater Horizons oil spill, which is now just 6-7 miles off Louisiana. The current strong winds may blow the muck to shore by Friday morning, the latest report says. obtained a list of 400 species put in harm’s way by the oil from the Louisiana Department of Natural Resources. Bob Marshall writes that this is a particularly horrible time for the oil spill–right when birds are migrating through or nesting. The soon-to-be oiled area is:

vital wintering or resting spot for more than 70 percent of the nation’s waterfowl, is used by all 110 neo-tropical migratory songbirds, and produces 50 percent of the nation’s wild shrimp crop, 35 percent of its blue claw crabs and 40 percent of its oysters. Ressearchers say 90 percent of all the marine species in the Gulf of Mexico depend on coastal estuaries at some point in their lives, and most of those estuaries are in Louisiana.

The New York Times has a great chart highlighting which species are most at risk, mostly migrating birds. The brown pelican was just removed from the endangered species list.

The Oiled Wildlife Care Network–a collection of wildlife responders across California–has sent its director down and is collecting info on volunteers.  They say it’s too late to train you to clean up animals but you could become a “convergent volunteer.” Specialized groups or state rehabber associations do

Pelicans, Otters, Manatees Could be Hurt by Deepwater Horizon Oil Spill

Endangered sea turtles, herons, white and brown pelicans, dolphins, whales, manatees, tuna and assorted sea birds  could all be hurt by the Gulf of Mexico oil spill that is now 16 miles off the tip of Louisiana and alarming wildlife officials all the way to Florida.

The Coast Guard is burning the oil, hoping that will keep it from making landfall and destroying wetlands. I wonder if, ironically, the giant dead zone in the gulf may mean that the area the oil spill hits may be devoid of life anyway. The next step for wildlife rescuers would be to herd animals out of the area by hazing them.  The International Bird Rescue Research Center in Texas says they’ve been put on alert for the decapitated oil well, which is gushing about 1,000 barrels (42,000 US gallons) of crude daily and already can be seen from space, with a circumference of 600 miles.

If the spill stays offshore then the impact will likely be minimal to birds. Coastal birds that are highly at risk if the spill hits shore are brown and white pelicans, terns, gulls, shorebirds, skimmers and herons. Nesting and feeding areas for birds and sea turtles such as marshes and beaches could be impacted.

Loggerhead and Kemp’s Ridley turtles are in the area, Live Science says. Birds are vulnerable if they ingest the oil or get coated in it. The

Manatees Making a Home in Mobile Bay, Alabama

We tend to think of manatees as living only in Florida and just barely hanging on there, but some exciting new research show they may be spreading to nearby Gulf states. Dr. Ruth Carmichael, senior marine scientist at the Dauphin Island Sea Lab near Mobile, AL, just tagged Alabama’s first officicial manatee resident. You can call the half-ton female “Bama.”

The big question is whether the endangered West Indian Manatee has been here all along, unbeknownst to people, or whether they’re expanding their range. Are people seeing more manatees because they’re looking? Nobody knows..  In 2007 Carmichael started the Mobile Manatees Sighting Network, which gives people a one-stop shop to call or email anytime they see a manatee. In just the first year people reported as many sightings as they had over the previous 30 years.

Carmichael hears from two types of people who live or work near the water. One has never seen them and doesn’t believe they’re there. The other tells her, “‘yeah, my kids have been swimming with them for 30 years.’” She then tries to gently convince them not to play with the manatees. Or give them the fresh water they crave. Since the manatee’s biggest enemy is boat propellers, if you teach them that it’s fun or profitable to hang around people, they have a greater chance of getting hurt. And technically, if you change an endangered species’ behavior, it’s a federal offense. Carmichael doesn’t want to play cop, but would love it if
