Here is a link to an interesting article on ducks. Apparently we have a mating pair where I work and one of our resident biologists has taken it upon himself to educate everyone about the care of wild ducks. I thought some in Towne Lake would find the information helpful too.

The problem here is the Ducks at Towne lake are generations being fed by residents. We usded to be guilty of this too until we found out that it may have contributed to a fungal infection in our cat, we decided fur before feathers. (especially when the meds are around $75.00 every 2 weeks for what's been a few months now) I wouldn't call the ducks around here wild, not really, not when they've come to depend on the humans more than their own natural instincts. Some Ducks are so trusting they'll let you pick up their ducklings, perhaps because they were picked up as ducklings. I'd say our ducks are somewhere in between wild and domesticated, but I would still be careful with the fungi. If people are going to feed them the lake would be the best place if you have pets, just my 2 cents.
