The nuthatch family, Sittidae, was described by René-Primevère Lesson in 1828. [3] [4]Sometimes the wallcreeper (Tichodroma muraria), which is restricted to the mountains of southern Eurasia, is placed in the same family as the nuthatches, but in a separate subfamily "Tichodromadinae", in which case the nuthatches are classified in the subfamily "Sittinae".
Krüper's nuthatch (Sitta krueperi) is a species of bird in the nuthatch family Sittidae. It is a small to medium-sized nuthatch, measuring 12.5 centimetres (4.9 in) in length. The upperparts are blue-grey, with the front half of the crown black in adults of both sexes, but with a less marked in the female rear.
The Eurasian nuthatch or wood nuthatch (Sitta europaea) is a small passerine bird found throughout the Palearctic and in Europe. Like other nuthatches, it is a short-tailed bird with a long bill, blue-gray upperparts and a black eye-stripe.

It can "walk" on the underside of branches. Unlike woodpeckers and creepers, it does not use its tail as a prop while climbing. [17] It tends to forage singly ...
In 2014, Eric Pasquet, et al. published a phylogeny based on examination of nuclear and mitochondrial DNA of 21 nuthatch species. The position of the beautiful nuthatch within the genus was not established with certainty, having a far lower statistical association than others in the model. Nevertheless, under the findings the species appears closest evolutionarily to three clades of nuthatches ...
No doubt, the Janson brothers — Homer, Ulysses, Atlas and Arlo — are lovely, well-behaved kids in real life. (Surely, no sanity-respecting director would cast them in a movie if that weren’t ...
