What’s small, blue-gray, and has a stripy-head?
Spiraling down a large pine trunk, you see a blue-gray bird with a striped head, long pointed bill, short tail, and a red wash on its breast, defying gravity as it travels in search of food. What is it? If you said Red-breasted Nuthatch, you are correct.
At home in stands of evergreens, the more canopy the better, the Red-breasted Nuthatch is found in our suburban areas wherever there are enough older conifers.
They use their strong legs and toes to rapidly climb down, sideways and even up, probing into crevices and cracks in the bark for insect eggs, moths of the spruce budworm, and any other delicacies that their long bills can pry out.
They nest in soft wood, such as alders, cottonwoods, pines, and dead snags. If you need to eliminate a tree, leave 15-20 feet of trunk and create a snag for wildlife. Since loss of habitat is the leading danger for birds, cavity-dwelling birds need our help to have large enough trees in which to hollow out their nest holes.

Red-breasted Nuthatches, Black-capped and Chestnut-backed chickadees, Northern Flickers, Downy, Hairy and Pileated woodpeckers, and Red-breasted Sapsuckers are our local cavity nesters.
Both members of the seasonally monogamous nuthatch pair work on creating the nest hole 5 to 100 feet up in the tree. A unique trait is that they keep the entrance hole coated with pitch. No one really knows why, but it is probably to repel invaders. Parents keep from getting pitch on their feathers by flying directly into the nest. They raise a single brood of three to six young that fledge in late May or June. Both parents feed this noisy bunch of busy, inquisitive youngsters.
If you offer black-oil sunflowers seeds and suet nearby, get ready to laugh as they seem to make suet sandwiches. They start by eating a sunflower or two, then go to the suet, take a bite, then go back and get another sunflower. Quite often they will make two or three trips to a nearby trunk to cache food for times of need.
So when you hear a tin-horn-sounding “Ank, ank, ank”, look for a small, stripy–headed, blue-gray bird travelling head first down an evergreen trunk, or loudly holding its place at your feeder.
