The eastern towhee is a large New World sparrow. The taxonomy of the towhees has been under debate in recent decades, and formerly this bird and the spotted towhee were considered a single species, the rufous-sided towhee.
The spotted towhee is a large New World sparrow. The taxonomy of the towhees has been debated in recent decades, and until 1995 this bird and the eastern towhee were considered a single species, the rufous-sided towhee. Literature before 1995 referred to the spotted towhee as a rufous-sided towhee that resides in the western United States. An archaic name for the spotted towhee is the Oregon towhee. The call may be harsher and more varied than for the eastern towhee.
The canyon towhee is a bird of the family Passerellidae.
A towhee is any one of a number of species of birds in the genus Pipilo or Melozone within the family Passerellidae.
Pipilo is a genus of birds in the family Passerellidae. It is one of two genera of birds usually identified as towhees.
The California towhee is a bird of the family Passerellidae, native to the coastal regions of western Oregon and California in the United States and Baja California Sur in Mexico.
Abert's towhee is a bird of the family Passerellidae, native to a small range in southwestern North America, generally the lower Colorado River and Gila River watersheds, nearly endemic to Arizona, but also present in small parts of California, Nevada, Utah, New Mexico, and Sonora in Mexico. The name of this bird commemorates the American ornithologist James William Abert (1820–1897).
The green-tailed towhee is the smallest towhee, but is still one of the larger members of the American sparrow family Passerellidae.
The olive sparrow is a species of American sparrow in the family Passerellidae. Its range includes Belize, Costa Rica, Guatemala, Honduras, Mexico, Nicaragua and southern Texas.
American sparrows are a group of mainly New World passerine birds, forming the family Passerellidae. American sparrows are seed-eating birds with conical bills, brown or gray in color, and many species have distinctive head patterns.
The collared towhee is a species of bird in the family Passerellidae that is endemic to Mexico. Its natural habitats are subtropical or tropical moist pine-oak montane forest and heavily degraded former forest. It occupies mountainous terrain from about 1,500 to 3,500 m.
Lyperosomum intermedium is a parasitic trematode belonging to the subclass Digenea that infects the marsh rice rat. The species was first described in 1972 by Denton and Kinsella, who wrote that it was closest to Lyperosomum sinuosum, known from birds and raccoons in the United States and Brazil. Three years later, Denton and Kissinger placed the two, together with a number of other species, in a new subgenus of Lyperosomum, Sinuosoides. Species of Lyperosomum mainly infect birds; L. intermedium is one of the few species to infect a mammal.
The Bermuda towhee is an extinct passerine of the towhee genus Pipilo that was confined to Bermuda. It was a large member of the genus and closely related to the eastern towhee. The scientific description was in 2012, based on Pleistocene and Holocene remains from Quaternary cave deposits. 38 bones from at least five individuals are known.
