The name Nuthatch probably results from the corruption of the word “nuthack” which refers to its habit of hacking away at a seed with its beak until the seed opens.
1. The name nuthatch probably results from the corruption of the word “nuthack,” which refers to its habit of hacking away at a seed with its beak until the seed opens.
2. White-breasted nuthatches will often store seeds for retrieval later in the same day or as a quick source of food for the next morning.
3. The white-breasted nuthatch is a common bird of deciduous forests and wooded urban areas. Known as the “upside down” bird, it’s often observed creeping headfirst down tree trunks while searching cracks and crevices for insects.
4. A nuthatch’s foot has one big toe (hallux) that faces backward, while its other three toes face forward. It’s able to walk head first down tree trunks by moving only one foot at a time while the hallux toe on the other foot holds firmly to the bark.
5. The white-breasted nuthatch commonly visits bird feeders. It typically takes a single sunflower seed and flies to a nearby tree, wedges the seed into the bark and hacks it open with repeated blows from its bill.
6. In a study of the white-breasted nuthatch's seed caching behavior, it was found that they selected unshelled sunflower seeds 25 percent more often than seeds in the shell. It appears that this preference is driven by the fact that it takes the nuthatch about half the time to transport and cache an unshelled seed than it does a shelled one.
7. Nuthatches are monogamous and defend a territory throughout the year. The female white-breasted nuthatch rarely strays far from her mate and stays in constant vocal contact while in close proximity.
8. In winter, white-breasted nuthatches will often forage together with other birds such as chickadees and downy woodpeckers in a group known as a foraging guild. Nuthatches recognize the alarm calls of these species and therefore reduce their own level of alertness by relying on vigilance of these other species. This leaves them with more time to concentrate on finding food.
9. The red-breasted nuthatch is an aggressive defender of its nesting cavity, especially during building. It chases away much larger birds, such as the downy woodpecker, and has been observed bullying the very aggressive house wren.
