A passerine is a bird of the order Passeriformes, which includes more than half of all bird species
A similar nomadic lifestyle is found in small passerine seed-eating birds such as redpolls and crossbills (Loxia spp.) in the forest tundra.
Moth larvae, particularly those in the family Geometridae (the “loopers” or “spanworms”), are a large component of the diet of many passerine birds in the boreal forest and near the forest/tundra margin.
In parallel, isotopic signatures of whole insect bodies and passerine muscular tissues were tracked throughout the year, serving as a control.
Moreover, a higher fraction of songbirds 'flesh in autumn than in spring was attributed to the more massive passerine migration in autumn, because both parents and offspring migrate then towards their wintering grounds in Africa, whereas in spring only birds having survived winter mortality return to their breeding area.
IMO, passerine parasitism is mainly due to their altricial nature.

The fossil passerine birds from the Pleistocene of Carpinteria, California.
Out of 178 species recorded ninety-six (54%) were passeriforms, eighty-two (46%) non-passerine.
The endemics include the highly threatened blue-eyed ground dove (Columbina cyanopis, CR), the Minas Gerais tyrannulet (Phylloscartes roquettei, CR), known only from three areas in the São Francisco valley in north and central Minas Gerais, and the Brasília tapaculo (Scytalopus novacapitalis), a passerine that is found only in a few populations in gallery forest remnants near Brasilia, and a few locations in Minas Gerais, including the Serra da Canastra National Park.
