Over the past week, vast waves of Warbling Vireos have been moving through southern coastal British Columbia, as I'm sure almost nobody has noticed. Caterpillars noticed though. "Look out, it's a Warbling V...!" The freshly-leafed birches, crawling with caterpillars, have been where many bugs met their ends--which they can actually do because they're very flexible.
Nabbed one. A little green job. Notice the fuzzy brown blob to the left of the bird. It's a terrified curled-up meaty larva. A tent caterpillar? Did the bird not see it, or are they not palatable? Or is it being kept for dessert--a big birdy bug bundt cake?
