Hummingbirds have returned to our gardens along with the rest of our summer birds. But with all the recent weather extremes, a cold snap is still possible. Enter the yellow-bellied sapsucker, one of our two migrant woodpeckers, the one that looks like its feathers are dirty. It makes hundreds of lentil-sized holes in its favorite apple or other trees, and these sap-wells are where hummingbirds, which migrate later than sapsuckers, drink when temperatures are cold enough to close flowers and send insects into hiding!
