When my aunt and uncle lived in the country near our cottage,they fed all kinds of birds, and encouraged them to nest. They had a colony of bluebirds, among others---and a couple of dozen pairs of hummingbirds.
On the way to the cottage, my wife and I stopped to visit, with our shiny new RED canoe on top of the van.
Well the H-bird tribe must have thought it was the motherlode of feeders! For a while it looked like an aerial dogfight, as they descended and swooped around the canoe. Cranky lil buggers that they are, they spent as much time swearing at, and chasing each other away. Until they realized it weren't really good to eat.
