Our cottage is on a small spring-fed lake and the major bird occupants are loons. They are supposedly aggressive toward other bird types, so they have the whole place to themselves. It's a nesting pair (they mate for life) and they usually have two chicks but last summer we had six adult and/or sub-adults, a very large group for such territorial birds. Love it when they do their happy-flappy dance on top of the water.
Loons and toucans, my favorites, and the wild parrots that wake us in in the mornings in Belize.
