question: The only bird commonly found in North America is the state bird of what state?
answer: Tennessee
context: Title: Aiolornis
  Passage: Aiolornis incredibilis (formerly "Teratornis incredibilis"), of the teratorn family, was the largest known North American flight-capable bird, with a wingspan of up to approximately 5 m and a huge, deep, powerful bill.  The typical body mass of this bird was estimated to be 23 kg , significantly heavier than any extant flying bird.  "A. incredibilis" presumably became extinct at the same time as the other megafauna in North America.  It is sometimes called the giant condor because of its resemblance to the modern condors of California and South America, although it is bigger and in a different family.  It is not well known but is quite similar to "Teratornis merriami", although about 40% larger overall.  Fossils have been found from the Early Pliocene to the Late Pleistocene in various locales in the southwestern and western-central part of the USA; it is not certain that all belong to the same species given the large time range and the lack of complete specimens.
  Title: Indian roller
  Passage: The Indian roller ("Coracias benghalensis"), is a member of the roller family of birds.  They are found widely across tropical Asia from Iraq eastward across the Indian Subcontinent to Indochina and are best known for the aerobatic displays of the male during the breeding season.  They are very commonly seen perched along roadside trees and wires and are commonly seen in open grassland and scrub forest habitats.  It is not migratory, but undertakes some seasonal movements.  The largest populations of the species are within India, and several states in India have chosen it as their state bird.
  Title: Northern mockingbird
  Passage: The northern mockingbird ("Mimus polyglottos") is the only mockingbird commonly found in North America.  This bird is mainly a permanent resident, but northern birds may move south during harsh weather.  This species has rarely been observed in Europe.
  Title: Scrappy Moc
  Passage: Scrappy is the mascot of the University of Tennessee at Chattanooga.  He is a mockingbird, the state bird of Tennessee.  Scrappy is named after the legendary, former Chattanooga football coach, A.C. "Scrappy" Moore.
  Title: American robin
  Passage: The American robin ("Turdus migratorius") is a migratory songbird of the thrush family.  It is named after the European robin because of its reddish-orange breast, though the two species are not closely related, with the European robin belonging to the Old World flycatcher family.  The American robin is widely distributed throughout North America, wintering from southern Canada to central Mexico and along the Pacific Coast.  It is the state bird of Connecticut, Michigan, and Wisconsin.  According to some sources, the American robin ranks behind only the red-winged blackbird (and just ahead of the introduced European starling and the not-always-naturally-occurring house finch) as the most abundant extant land bird in North America.  It has seven subspecies, but only "T. m. confinis" of Baja California Sur is particularly distinctive, with pale gray-brown underparts.
  Title: Lark bunting
  Passage: The lark bunting ("Calamospiza melanocorys") is a medium-sized American sparrow native to central and western North America.  It is also the state bird of Colorado.
  Title: Bird hide
  Passage: A bird hide (or hide, British usage; known as a blind or bird blind in North America,) is a shelter, often camouflaged, that is used to observe wildlife, especially birds, at close quarters.  Although hides or hunting blinds were once built chiefly as hunting aids, they are now commonly found in parks and wetlands for the use of bird watchers, ornithologists and other observers who do not want to disturb wildlife as it is being observed.
  Title: Red-winged blackbird
  Passage: The red-winged blackbird ("Agelaius phoeniceus") is a passerine bird of the family Icteridae found in most of North and much of Central America.  It breeds from Alaska and Newfoundland south to Florida, the Gulf of Mexico, Mexico, and Guatemala, with isolated populations in western El Salvador, northwestern Honduras, and northwestern Costa Rica.  It may winter as far north as Pennsylvania and British Columbia, but northern populations are generally migratory, moving south to Mexico and the southern United States.  Claims have been made that it is the most abundant living land bird in North America, as bird-counting censuses of wintering red-winged blackbirds sometimes show that loose flocks can number in an excess of a million birds per flock and the full number of breeding pairs across North and Central America may exceed 250 million in peak years.  It also ranks among the best-studied wild bird species in the world.  The red-winged blackbird is sexually dimorphic; the male is all black with a red shoulder and yellow wing bar, while the female is a nondescript dark brown.  Seeds and insects make up the bulk of the red-winged blackbird's diet.

He is also the author of "Bird Watching For Dummies" (1997, John Wiley & Sons), and author of 18 different state bird watching books in the "Bird Watching: A Year-Round Guide" series from Cool Springs Press (2005).

  Title: Pohnpei fantail
  Passage: The Pohnpei fantail ("Rhipidura kubaryi") is a fantail which is endemic to the Pacific island of Pohnpei in the Federated States of Micronesia.  It is a bird commonly found in forests and at forest edges.  It feeds on insects which it gathers by gleaning amongst foliage or by making short dashes while in the air.
