Woodpecker Tidbits

Did You Know? Most woodpeckers have an X-shaped footprint. Also, they have nostril feathers to prevent inhalation of wood particles as they chisel.

FEET: All woodpeckers have an X-shaped footprint. Most bird species have three toes pointing forward and a "thumb" pointing back, but woodpeckers, parrots, owls, and ospreys have zygodactyl feet, which means two toes point forward, and two point backward. This gives woodpeckers stability when clinging to tree trunks while they hammer their bills against it.

TONGUE: The base of a woodpecker's tongue is above its eye sockets. The tongue forks around the back of the bird's skull and extends through its lower bill. The long tongue provides cushioning to the skull as the bird hammers a tree trunk. The tip of a woodpecker tongue is barbed, better for snagging insects from within a tree, or for lapping sap. From base to tip, a red-bellied woodpecker's tongue measures more than nine inches when extended!

TAIL: A woodpecker's central tail feathers are extra stiff for support against a tree trunk. These feathers, along with stable, zygodactyl feet, provide the stability and balance of a three-legged stool.

NOSTRIL FEATHERS: Tiny feathers cover woodpeckers' nostrils to prevent inhalation of wood particles as they chisel.

SPECIES: Twenty-two species of woodpecker reside in North America, but species of woodpecker can also be found in Central and South America, Eurasia, and Africa.

  • 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

  • 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
