The Passeriformes contains 5,000 or so species [1] [2] found all over the world, in which the vocal organ typically is developed in such a way as to produce a diverse and elaborate bird song. Songbirds form one of the two major lineages of extant perching birds (~4,000 species), the other being the Tyranni (~1,000 species), which are most ...
Various Passeriformes (perching birds) are commonly referred to as warblers. They are not necessarily closely related to one another, but share some characteristics, such as being fairly small, vocal, and insectivorous.
In total there are about 11,000 species of birds described as of 2024, [1] though one estimate of the real number places it at almost 20,000. [2] The order passerines (perching birds) alone accounts for well over 5,000 species.
Psittacopasseres is a taxon of birds consisting of the Passeriformes (passerines, a large group of perching birds) and Psittaciformes (). [3] Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising passerines, psittacines and Falconiformes. [4]

Eurasian and red-breasted nuthatches are lowland birds in the north of their extensive ranges, but breed in the mountains further south; for example, the Eurasian nuthatch, which breeds where the July temperature range is 16–27 °C (61–81 °F), is found near sea level in Northern Europe, but between 1,750 and 1,850 m (5,740 and 6,070 ft ...
