Passeriformes, more commonly known as perching birds or passerines, are the most species-rich group of birds. Totaling nearly 6500 species, approximately two out of every three bird species is a passerine. Passerines are globally distributed and are among the most abundant birds at nearly every terrestrial location on Earth.

Polyterritorialitytion in passerine birds
Trends in Ecology & Evolution, 1989In some birds, males defend two spatially separated territories and attract females to each one in turn. it has been proposed that this behaviour, referred to as polyterritoriality, allows males to conceal their marital status, thereby deceiving females into accepting polygyny against their best interests.

Lead shot toxicity to passerines
Environmental Pollution, 2001This study evaluated the toxicity of a single size 7.5 lead shot to passerines. No mortalities or signs of plumbism were observed in dosed cowbirds (Molothrus ater) fed a commercial diet, but when given a more natural diet, three of 10 dosed birds died within 1 day.

Physical Examination of Passerines
Veterinary Clinics of North America: Exotic Animal Practice, 1999A physical examination of a passerine incorporates the same basic techniques used for other avian species. Although frequently a concern for practitioners, the small size of many of these patients can be overcome with a few technical and equipment modifications.

MOUTHSPOTS OF PASSERINE NESTLINGS
Ostrich, 1976Summary Maclean, G. L. & Vernon, C. J. 1977. Mouthspots of passerine nestlings. Ostrich 48:95-98. Among passerine families a pattern of black spots in a yellow mouth occurs universally only in the Sylviidae and the Alaudidae. The conservative configuration of these spots seems to indicate a true relationship between the warblers and the larks, and the ...

Ventral-clap modes of hovering passerines
Physical Review E, 2013Some small birds typically clap their wings ventrally, particularly during hovering. To investigate this phenomenon, we analyzed the kinematic motion and wake flow field of two passerine species that hover with the same flapping frequency. For these two birds, the ventral clap is classified as direct and cupping.

Passerine birds (Passeriformes)
2009Abstract The Order Passeriformes is the largest clade of its rank in birds, encompassing from roughly 40–100 families depending on the classification. In recent years molecular systematic data have greatly clarified interfamilial relationships, although many nodes remain poorly supported and it is clear that numerous traditional families

Comparative Biochemistry and Physiology Part A: Physiology, 1993
Abstract 1. 1. Eight species of passerines were evaluated for their ability to form conditioned responses to odor stimuli. Only 5 species met training criteria and were tested for odor detection thresholds. 2. 2. Detection thresholds were comparable to other passerines tested.
