Now that things have warmed up a bit, the welcome mat is out for the ruby-throated hummingbird, which is beginning to arrive from the tropics. It’s time to get out your feeders.

While we may think of hummingbirds as nectar eaters, they also consume large quantities of small insects. And so do scores of other birds arriving now and in the next month or so. In fact, that’s why most of them await spring to come north: They are primarily insect eaters and must wait for winter to depart and their meals to emerge.
