Canaries mate once a year, but I have a feeling these two have been together awhile. For one thing, look at how pudgy they are. That’s a lot of worms. And only birds who know one another really well have the patterns of feeding each other down pat. Yes, I’m convinced they know one another well—find each other at mating time and look like this, a lot! Perhaps they survived the coal mines or one rescued the other. But there’s a lot of love goin’ on in that tree.
