Where I live in north Idaho, there are 2 birds that eat (and look for food) upside-down. They are the rose-breasted nuthatch and the pygmy nuthatch.

The Nuttall's Woodpecker will hang upside down under limbs looking for insects under the bark.

There are no perfect rhymes for the word nuthatch.

Kenneth Joseph Kowalczyk has written:

'Spatio-temporal variations in the foraging behavior of the pygmy nuthatch (Sitta pygmaea)' -- subject(s): Nuthatches

Actually, a Nuthatch is a bird, not a fish or a plant.

The Corsican nuthatch is found only on the island of Corsica, in the Mediterranean Sea. It is also the only nuthatch found on Corsica.
