Songster of the Conifers–beautiful but invisible?

Red-breasted Nuthatch

If you have entered the world of the conifers above the Central Valley, or throughout most of North America for that matter, you stand a good chance of having heard an ongoing, nasal ankh, ankh, ankh, ankh. It is the song of the red-breasted nuthatches, elfin birds of our pines and firs.

They are harder to see than hear; they don’t seem shy, but they are small, and much of their living happens far over our heads. Nuthatches are built for prying insects from the bark of trees. Their bill is slightly dished up and stout enough to shovel bugs from crevice hide-aways. Their shoulders are broad, relatively speaking, and provide the heft to wield their strong bills. Their long hind toe is used, uniquely in the bird world, to hold them in place while they hunt face-down on a tree trunk or branch. Their tails are stiff, allowing them to prop against a tree as they pound against it.

And what do they pound? In addition to picking insects from cracks in tree trunks, these nuthatches gather seeds from cones at branch-tips. They often wedge hard pine-nuts into crannies in the bark and then crack them open with hammer blows from their bills. Also, these versatile gymnasts, like woodpeckers, carve out their own cavities for nesting. No fools, they prefer the softer wood of dead limbs and snags for their home-building.

Males often begin several nesting holes as part of their courting. A female takes over and shapes the chosen cavity to her liking, taking about two weeks to complete the excavation. Both adults apply sap to the hole entrance–he on the exterior, she on the interior. The tiny nuthatches dive right through the hole without getting gummed up, but predators, from owls to ants, can be deterred by the sticky goo.

He begins feeding the female, and she lays a handful of eggs in their nest. The young hatch, naked and blind, after two weeks of incubation. Another two weeks and, having been fed and protected by both parents, the young fledge into the world.

There, if you enter that world of the conifers, you may be able to see them. A little luck and a decent pair of binoculars will let you enjoy the red-breasted nuthatch’s gray-blue back, chestnut underside, and black eyeline under a white eyebrow. Otherwise, at least you may enjoy their ubiquitous song–ankh, ankh, ankh…

Listen for a Nasal Beeping in Your Neighborhood Trees

White-breasted Nuthatch

In the bird world of the North State, there’s little that’s more common than a nuthatch. You’ll find more avian tonnage in winter refuges and flooded fields, and you’ll find brighter plumages and louder songsters. But nuthatches are year-round decorations in our native trees.

You can scarcely go for a walk up in the fir belt without hearing the tiny red-breasted nuthatches. These little cuties may be tough to see as they pick small insects from high-up in the conifers, but their quick, nasal ankh-ankh-ankh-ankh-ankh calls can be relentless and ubiquitous as they keep in touch with one another.

Down in the oak woodlands, the larger, teacup-sized white-breasted nuthatches fill the woods with calls that are similar but a touch more mellow, slower and lower.

The white-breasteds are often easily viewable, as they usually forage not in twig-tip foliage but on the open expanse of exposed trunks and large limbs. Also helpful for viewing, the oaks are shorter than firs, and many will later lose their leaves. With their regular calling and white faces that stand out against dark trunks, white-breasted nuthatches are one of the most visible little birds in the trees. When flying away, they may flash more white at the corners of their tails. You may be able to see their blue-gray backs, and, in the males, their nape and crown darkened to a rich blue-black.

But it is nuthatch behavior that really stands out. Most birds are like us–our feet are down and our heads are up. But nuthatches give the world a different look. Their regular habit is to fly high and work their way down a trunk. They pick for insects in bark fissures, and the down-trunk approach gives them a view into crevices that woodpeckers and other gleaners miss. Perhaps that less common world view helps lead to their success. These nuthatches are widespread across North America.

Their visibility can be enhanced in your own yard, especially if nearby you have some of the big old oaks they favor. Nuthatches will frequent feeders, especially those offering sunflower seeds. Unlike finches and sparrows, they dine take-out style. They will select a seed and fly away with it. If you can follow their flight, you may see them wedge the seed into some bark, either for later consumption or to hold it there as they bang at it with their bills to “hatch the nut” out! They will nest in cavities of old limbs or in nesting boxes that you can place in your yard.

Nuthatches lay a half dozen or more eggs each spring, and their populations have increased over the last fifty years. They are expected to remain regular winter residents of the North State, but are likely to move north for breeding as they deal with climate change.
