Caterpillars for the Birds

A Monarch butterfly (Danaus plexippus) caterpillar feeds on a leaf.

Most nesting birds feed their young protein in the form of insects, especially soft and juicy caterpillars. Some birds are strictly insectivorous, and those are unlikely to visit your seed feeders. A great way to see warblers, vireos, and other such birds is to encourage caterpillars in your garden. At your local garden center, ask for native host plants—varieties that butterflies and moths use for egg laying. The eggs will grow into larva, aka caterpillars, aka bird food.

    I am excited to have my daughter’s tree this year, since my landlord has removed the lovely yew next to my patio, which was the only shelter for birds at my feeder.

    Goldfinches will continue as long as Swiss chard is available. I'm watching one eating chard right now (mid-November in Vermont).

    Birds are on the decline though sunflowers are rarely touched and for weeks hardly .eaten. I'll try a few sparing nuts on the table and a fat ball broken for jackdaws and tits but mealworms were a summer favourite being my go to choice

  • Re: On Thistle and Goldfinches in Winter » Watching Backyard Birds.com
    I’ve been enjoying goldfinches eating coneflower/ echinacea seeds in my new pollinator garden! I will leave the plants out all winter for them if the seeds keep that long? Or should I deadhead and put them in a dry area? Im in CT and thought they migrated, but didn’t know they put in winter coats! What do they eat in winter without bird feeders?

    Hi Gary, I will pass your question along to Birdsquatch next time I see him. He knows infinitely more about nocturnal wildlife than I do. Where do you live? That's pretty important in figuring out the answer. But the thief could be raccoons, deer, or flying squirrels. Do you live in the woods? Are there trees near your feeder, or must the culprit climb a shepherd's hook or pole? Dawn Hewitt, Watching Backyard Birds
