We are in the middle of a family's breeding territory, so we only see that family during breeding months. They leave around Aug/September before the bad hurricanes come, but one or two will check on this territory about once a week, in general. We see the larger flocks only overhead, flying south or north. They don't land here for foraging or roosting. I guess we're a "flyover" island, ha! We do get huge flocks of Lesser Scaups here on the Banana River, though, in the late winter/early spring. There can be many hundreds of scaups in these flocks.
