1、Manatee of the Month: Flicker Flicker checks out a researcher doing manateephoto identification work. (Photo courtesy of FWCC)When you first see Flicker, you cant help but notice the many small propeller scars that run across her back. When she was identified in 1983 near Ft. Myers, Florida, a Flori

2、da Fish and Wildlife Conservation Commission (FWCC) researcher commented that her scars looked like flickering flames. Thats how she got her name. Flicker has had more than one run-in with a boat. Her tail is missing a few chunks from contact with a propeller, and shes also had her share of entangle

3、ment woes (more on that later). But that hasnt stopped her from racking up manatee miles on her frequent trips around Tampa Bay.In the winter, Flicker hangs out at Tampa Electric Companys (TECO) power plant in Apollo Beach, Florida. Manatees cant tolerate water temperatures below 21 C (70 F), and th

Besides visiting the TECO plant, Flicker also makes trips across the bay to the Florida Progress plant in Bartow. After all, she doesnt want to play favorites!

7、escue staff had arrived, Flicker - who is a big manatee - had stripped off one of the bouys and almost swamped a law enforcement boat. It took three attempts by the rescue staff (along with a couple of cleats and several planks from the houseboat) before she was free. Both Flicker and her rescuers e

8、scaped with no injuries. And shes still continuing to trek across Tampa Bay. In fact, last winter, she was a bay-wide traveler, visiting TECO, the Florida Progress power plant, and Culbreath Key (across the bay from Florida Progress) all in one year. The winter fluctuated between cold and warm weath

9、er, and Flicker may have decided to hightail it to Bartow when things warmed up a bit. The warm water disperses faster there on the unprotected flats, but lush seagrass beds can be found, so there are always good eats!Were happy to report that last spring Flicker was spotted with six other adults in the Culbreath Isles area - in an area newly protected by boat speed zones for manatees. Flicker keeps on truckin across Tampa Bay. (Photo courtesy of FWCC)
