Nut Hatch
in ornithology, Sitta Europæa, a well-known bird; the upper parts delicate bluish-gray, sh-gray, throat white, under parts reddish brown, rich chestnut on flanks. It is extremely shy. The bill is wedge-shaped; in habits it resembles the creeper, but has the power of descending the trunk of a tree head downward, which the latter bird never does. The nut hatch is insectivorous, using its bill to pry off the bark to get at the insects underneath.
