After reading this post on The Zen Birdfeeder blog, I went and found my hummingbird feeders and mixed up a batch of food for them. Then, I hung out their feeders and waited. My feeders hang on the log edges of my house, so you can't see them from the inside at all, and at first I thought they were not coming. Maybe they had already migrated to warmer climates. However, after just a couple of days I started to see them buzzing past the windows. Since then they've been a regular visitor, there's at least two pairs, and they take it in turns to fly from tree to feeder and back again. If you sit quietly in the corner of the deck they'll buzz right over your head, pretty cool hearing their little wings going so fast.
