This female and one of the males have been spending the spring and summer here for years - I've seen the same two ducks for 3 years running now. This other male is just a usurper and needs to be chased off - the other one is doing a good job chasing off the newcomer or I would've helped
We have ducks around the area alot. Outside of the apartments we have a small park for the kids, about 4 times a week I see a few pairs of ducks. The main park in town is huge, and has a specific area where ducks and geese go and people feed them. Thats really fun to do this time of year.
