Last week it was White-throated Sparrows. This week it's White-crowned Sparrows in the backyard (see photo above). I also have Chipping Sparrows and a tan-coloured version of the White-throated sparrow. A few streets away, in the centre of the village, my friend Gerry Binsfeld has a Carolina Wren in his backyard. That bird is not one of the usual suspects. It is a rare, year-round resident in Ontario, just barely making it to the north shores of Lake Erie and Lake Ontario during the spring migration.
