Q. How did the nuthatch get its name?
A. Nuthatches have a habit of tucking food like nuts and seeds into tree bark and then "hacking" (thus "hatching") away at it with their pointy bill to extract the seed or nut.
White-breasted Nuthatches and Red-breasted Nuthatches are common at birdfeeders, which provides us a good opportunity to observe this behavior. Watch them take a seed or nut from the feeder, fly to a nearby tree, and tuck it away in the bark. They may then hack away at it to open it, or leave it for retrieval later.
