Our city rarely gets significant snowfalls but the recent two-week spell of below zero temperatures resulted in a winter wonderland. Yesterday morning, as huge snowflakes continued to fall, my husband and I relaxed with our Sunday morning coffee, enthralled by the beauty just beyond our living room's glass walls. He wondered aloud if hummingbirds flew in these conditions. He had been bringing the feeder in at night, then returning it each morning. We had seen hummingbirds on the clear days, but this morning, nothing. However, just minutes after he spoke, two of them arrived, a male and a female. We were then honoured with a magnificent performance of them flying side by side, for the longest time, all over the back yard. Their endurance was incredible. What a show! Finally, they settled at the base of the feeder pole, the male hovering over the female, and engaged in mating. We could hardly believe our good fortune - the gift of witnessing these tiny, spirited creatures doing something we had never seen. So the answer to the question is yes, they do, and in the case of these two sweethearts, with gusto!
