It's quite sad because obviously the alligator cannot survive a winter in the pond. I hope someone is able to capture it and deliver it to a refuge or zoo. All because some idiot tried to keep it as a pet and released it once it got too big... Speaking of which, anyone remember the move Alligator (1980)? Great movie.

I recently went birding in Rhode Island with my BwBTC (birders who blog, tweet, chirp) group, but fortunately we didn't encounter any alligators! I did see a huge snapping turtle sticking its beak out of the water to breathe (while at Trustom Pond National Wildlife Refuge, another popular RI bird watching spot), but that was the largest reptile spotted.
Check back for pictures from the BwBTC trip- uploaded but certainly not sorted through yet... I'm getting there :)
