Ruby-throated hummingbird

The first sign is a tiny, fearless blur at the feeder, usually in mid-May, as if someone had flicked a jewel across the garden. The ruby-throated hummingbird is the only hummingbird that breeds in Manitoba, and the males arrive first, with the females following close behind. They spend the summer working bee balm and zinnias, guarding their favourite patch with a ferocity far out of proportion to their size.

A ruby-throat weighs roughly as much as a nickel. Its wings beat around 50 times a second, and in flight its heart can top 1,000 beats a minute. The red throat belongs to the males, and it only flashes when the light hits at the right angle; otherwise it looks dark. By late August and September they fatten up and leave, and some cross the Gulf of Mexico in a single non-stop flight of about 800 kilometres.
