Time for the nasty COOTS to leave! We have a thousands of these things that migrate to our lakes every winter. They foul up the walkways, stir up the dogs, and they are not very attractive to boot. They usually spend the winter and then in early spring go back to where ever they came from.
The development owners decided the best way to deal with the coots was to eliminate rye grass overseeding in the common areas around the lakes, thereby eliminating the coot's food source. They intended to dye the dry bermuda grass a green color to retain winter beauty.
For some reason, that plan fell through, and the coots remained. Maybe next year they'll come up with a workable solution.
