Common Gallinule and Mottled Duck

Two duck like birds that I often see in S.W. Florida are the Common Gallinule and Mottled Duck.

The Common Gallinule shown in the picture above also known as the Common Moorhen has a dark body, and red bill and often swims in ponds, lakes, streams and other wetland bodies, feeding upon seeds of grasses and sometimes snails. It is able to walk on top of aquatic vegetation or mud flats with its long toes.  It is also an excellent swimmerand will dip its head in the water looking for food. The Common Gallinule makes a loud screeching call and sound and can be reproduced on the All About Birds website. It is listed on the threatened list of birds in America because of predation by other animals and loss of habitat.

The Mottled Duck is distinguished by its multi-colored feathers on its body, green bluish colors on its tail, lighter colored neck and head and yellow bill. Its picture is also shown above. Like the Common Gallinule, it also makes its habitat in fresh water marshes, ponds, lakes and estuaries. It feeds upon the seeds of grasses, aquatic vegetation, small fish and marine invertebrates.  The Mottled Duck is in danger of becoming extinct because of its breeding with the similar Mallard Duck which produces a hybrid version of the Mottled Duck. It is also hunted throughout the United States for sport. You can learn more about the Mottled Duck and Common Gallinule  on the All About Birds or Florida Audubon websites.

 

 

 

 

 

 

 

Gopher Tortoise

I came across this Gopher Tortoise while riding my bicycle on Sanibel Island along the Sanibel-Captiva Rd.  The Gopher Tortoise was slowly crawling along a grassy area and eating grass. This reptile is a land dwelling animal and lives in a burrow that it digs for itself with its’ strong claws.

The burrow that it digs averages 6.5 feet deep and 15 feet long. The burrow provides refuge or habitat for up to 350 other species. The Gopher Tortoise is called a keystone species for this reason because of its importance for helping to insure the survival of other species in its ecosystem.  The animals that typically live in the Gopher’s burrow include burrowing owls, rattlesnakes, crickets and many others.

The habitats that this reptile lives in include dry uplands, sandhills, pine flatwoods, scrub, dry prairies, xeric hammocks, pine mixed hardwoods and coastal dunes. They depend on natural fires to burn away the brush, dead leaves and shrubs so that new plants and grasses can grow. The Gopher Tortoise has been around for a long time and its estimated to date back  60 milliion years. The Gopher Tortoises’ life time averages 40-60- years.

The Gopher Tortoise itself is as a threatened species in Florida and is protected by the laws of the state against poaching or hunting.  No land clearing or development can take place in an area where a tortoise lives unless it is relocated to a similar environment and permits are issued for its relocation. The Florida Fish and Wildlife Commission has additional information about this animal. http://myfwc.com/wildlifehabitats/managed/gopher-tortoise/
