The buff-bellied pipit or American pipit (Anthus rubescens) is a small songbird found on both sides of the northern Pacific. It was first described by Marmaduke Tunstall in his 1771 Ornithologia Britannica. [2] It was formerly classified as a form of the water pipit. It is known as "American pipit" in North America and "buff-bellied pipit" in Eurasia.
Like most other pipits, the buff-bellied pipit is an undistinguished-looking species which usually can be seen to run around on the ground. The rubescens subspecies (or American pipit) has lightly streaked grey-brown upperparts and is diffusely streaked below on the buff breast and flanks. The belly is whitish, the bill and legs are dark. The japonicus subspecies (or Japanese pipit) is darker above and has bolder black streaking on its whiter underparts; its legs have a reddish hue. [3] [4] The call is a squeaky sip. [4]

The scientific name is from Latin. Anthus is the name for a small bird of grasslands, and the specific rubescens means "reddish", from ruber, "ruddy". [6]
Four subspecies are currently recognized belonging to two main groups. Morphological and DNA sequence differences between them are rather pronounced and they might be considered distinct species pending further research: [4] [7]
This species is closely related to European rock pipit (A. petrosus) and water pipit (A. spinoletta), all three forms having previously been considered conspecific. They can be differentiated by their vocalizations and some visual cues, but rock and buff-bellied pipit are not found sympatrically except as vagrant individuals, and the ranges of buff-bellied and water pipits overlap only in a small area in Central Asia. [3] [9] [10]
Both subspecies of the buff-bellied pipit are migratory. The buff-bellied pipit winters on the Pacific coast of North America, and on the Atlantic coast from the southern North America to Central America. [1] At least regarding the buff-bellied pipit, its wintering range seems to have expanded northwards in the 20th century and the birds seem to spend less time in winter quarters: in northern Ohio, for example, the species was recorded as "not common" during migration in May and September/October in the 1900s (decade), but today it is considered a "widespread migrant" in that region, found between March and May and from late September to November, with many birds actually wintering this far north. Asian birds winter mainly from Pakistan east to and Southeast Asia, with occasional birds found as far north as Yunnan and some in Japan apparently being all-year residents or migrating but a little. The American and Asian subspecies are rare vagrants to Western and Eastern Europe, respectively. [4] [11] [12] [13]
Like its relatives, this species is insectivorous. [14] The breeding habitat of buff-bellied pipit is tundra, but outside the breeding season it is found in open lightly vegetated areas, similar to those favoured by the water pipit (A. spinoletta). [4]
The first thing buff-bellied pipits do when they arrive on the breeding site, during snowmelt, is pairing. Indeed, males will start to fight one on one to win over the female and pair with it during the entire breeding season. They also fight for the snow-free sites that would be better for nesting. The moment is also very important because the melting snow implies an increase in arthropods abundance, which constitute the main food source for these birds. After the fight and the pairing, nesting is the next step. Nests are most often found on the ground in dry or wet meadows, always with a helpful protection, but they are never placed in shrubs or trees. [15] [16] The composition of the ideal nest depends on whatever is around the nesting area, but it is usually made of sedge, remains or new fine grass, and sometimes some horse hairs. [16] The final issue buff-bellied pipits have to deal with is nest success. The nest is indeed the target for numerous predators such as ants or hawks. If this step is successful, an egg can be produced. [16] The female will not lay an egg if the conditions, such as temperature and nesting site, are not optimal. If the first attempt fails, her time to lay an egg is reduced. In general, buff-bellied pipits continuously lay eggs over a period of 4 to 5 days after snow-melt (in April–May) until mid-July. After this period, the male testes decrease in size and the female refuses any copulation. [17] The clutch size is usually 5 eggs but it can vary according to snowfalls, the parents' reproductive ability and predation. [15] Eggs are incubated for 13–14 days. [17] [18] During this time, the female does not leave the nest, but is still very reactive to any movement around her. She communicates by singing to the male that brings her food and defends their territory. Four or five days after hatching, the young is skinny, blue-gray in color, and only has its secondary feathers. For a week, the female will brood the clutch, but both parents will feed them. After these 7 days, the birds are ready for fledging but they will still be fed by their parents for 14 days after their departure. Finally, immature birds will form little flocks with other immature birds and wander off. [16] [18]
It is a widespread and common species and not considered threatened by the IUCN. [1]
The cuckoo, common cuckoo, European cuckoo or Eurasian cuckoo is a member of the cuckoo order of birds, Cuculiformes, which includes the roadrunners, the anis and the coucals.
The white wagtail is a small passerine bird in the family Motacillidae, which also includes pipits and longclaws. The species breeds in much of Europe and the Asian Palearctic and parts of North Africa. It has a toehold in Alaska as a scarce breeder. It is resident in the mildest parts of its range, but otherwise migrates to Africa. In Ireland and Great Britain, the darker subspecies, the pied wagtail or water wagtail predominates; this is also called in Ireland willie wagtail, not to be confused with the Australian species Rhipidura leucophrys which bears the same common name. In total, there are between 9 and 11 subspecies of M. alba.
The pipits are a cosmopolitan genus, Anthus, of small passerine birds with medium to long tails. Along with the wagtails and longclaws, the pipits make up the family Motacillidae. The genus is widespread, occurring across most of the world, except the driest deserts, rainforest and the mainland of Antarctica.
The wagtails, longclaws, and pipits are a family, Motacillidae, of small passerine birds with medium to long tails. Around 70 species occur in five genera. The longclaws are entirely restricted to the Afrotropics, and the wagtails are predominantly found in Europe, Africa, and Asia, with two species migrating and breeding in Alaska. The pipits have the most cosmopolitan distribution, being found mostly in the Old World, but occurring also in the Americas and oceanic islands such as New Zealand and the Falklands. Two African species, the yellow-breasted pipit and Sharpe's longclaw, are sometimes placed in a separate seventh genus, Hemimacronyx, which is closely related to the longclaws.
The killdeer is a large plover found in the Americas. It gets its name from its shrill, two-syllable call, which is often heard. It was described and given its current scientific name in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae. Three subspecies are described. Its upperparts are mostly brown with rufous fringes, the head has patches of white and black, and two black bands cross the breast. The belly and the rest of the breast are white. The nominate subspecies breeds from southeastern Alaska and southern Canada to Mexico. It is seen year-round in the southern half of its breeding range; the subspecies C. v. ternominatus is resident in the West Indies, and C. v. peruvianus inhabits Peru and surrounding South American countries throughout the year. North American breeders winter from their resident range south to Central America, the West Indies, and the northernmost portions of South America.
The grey wagtail is a member of the wagtail family, Motacillidae, measuring around 18–19 cm overall length. The species looks somewhat similar to the yellow wagtail but has the yellow on its underside restricted to the throat and vent. Breeding males have a black throat. The species is widely distributed, with several populations breeding in Eurosiberia and migrating to tropical regions in Asia and Africa. The species is always associated with running water when breeding, although they may use man-made structures near streams for the nest. Outside the breeding season, they may also be seen around lakes, coasts and other watery habitats. Like other wagtails, they frequently wag their tail and fly low with undulations and they have a sharp call that is often given in flight.
The European rock pipit, or simply rock pipit, is a species of small passerine bird that breeds in western Europe on rocky coasts. It has streaked greyish-brown upperparts and buff underparts, and is similar in appearance to other European pipits. There are three subspecies, of which only the Fennoscandian one is migratory, wintering in shoreline habitats further south in Europe. The European rock pipit is territorial at least in the breeding season, and year-round where it is resident. Males will sometimes enter an adjacent territory to assist the resident in repelling an intruder, behaviour only otherwise known from the African fiddler crab.
The water pipit is a small passerine bird which breeds in the mountains of Southern Europe and the Palearctic eastwards to China. It is a short-distance migrant; many birds move to lower altitudes or wet open lowlands in winter.
Richard's pipit is a medium-sized passerine bird which breeds in open grasslands in the East Palearctic. It is a long-distance migrant moving to open lowlands in the Indian subcontinent and Southeast Asia. It is a rare but regular vagrant to western Europe.
The meadow pipit is a small passerine bird, which breeds in much of the Palearctic, from southeastern Greenland and Iceland east to just east of the Ural Mountains in Russia, and south to central France and Romania; an isolated population also occurs in the Caucasus Mountains. It is migratory over most of its range, wintering in southern Europe, North Africa, and south-western Asia, but is resident year-round in western Europe, though even here many birds move to the coast or lowlands in winter.
The red-throated pipit is a small passerine bird,which breeds in the far north of Europe and the Palearctic, with a foothold in northern Alaska. It is a long-distance migrant, moving in winter to Africa, South and East Asia and the West Coast United States. It is a vagrant to Western Europe.
The Pechora pipit is a small passerine bird which breeds in the East Palearctic tundra and densely vegetated areas near river banks ranges from the Pechora River to the Chukchi Peninsula. It also breeds in Kamchatka and the Commander Islands. It is a long-distance migrant, moving in winter to Indonesia. Rarely in September and October, the Pechora pipit may be observed in western Europe. The species was first described by Robert Swinhoe in 1863.
The tree pipit is a small passerine bird which breeds across most of Europe and the Palearctic as far East as the East Siberian Mountains. It is a long-distance migrant moving in winter to Africa and southern Asia. The scientific name is from Latin: anthus is the name for a small bird of grasslands, and the specific trivialis means "common".
The Nashville warbler is a small songbird in the New World warbler family, found in North and Central America. It breeds in parts of the northern and western United States and southern Canada, and migrates to winter in southern California and Texas, Mexico, and the north of Central America. It has a gray head and a green back, and its underparts are yellow and white.
The paddyfield pipit or Oriental pipit is a small passerine bird in the pipit and wagtail family. It is a resident (non-migratory) breeder in open scrub, grassland and cultivation in southern Asia east to the Philippines. Although among the few breeding pipits in the Asian region, identification becomes difficult in winter when several other species migrate into the region. The taxonomy of the species is complex and has undergone considerable changes.
The long-billed pipit or brown rock pipit is a passerine bird which has a wide distribution. A number of subspecies have been created for the populations in Africa, through the Arabian peninsula and South Asia. The systematics of this complex is yet to be clarified. Most birds are residents or short distance migrants.
Sprague's pipit is a small songbird (passerine) in the family Motacillidae that breeds in the short- and mixed-grass prairies of North America. Migratory, it spends the winters in the southwestern United States and northern Mexico. Sprague's pipits are unusual among songbirds in that they sing high in the sky, somewhat like a goldfinch or skylark. It is more often identified by its distinctive descending song heard from above than by being seen on the ground. Males and females are cryptically coloured and similar in appearance; they are a buffy brown with darker streaking, slender bills and pinkish to yellow legs. Sprague's pipit summer habitat is primarily native grasslands in the north central prairies of the United States and Canada. The species was named after the botanical illustrator Isaac Sprague.
The Australian pipit is a fairly small passerine bird of open country in Australia and New Guinea. It belongs to the pipit genus Anthus in the family Motacillidae.
The African pipit is a fairly small passerine bird belonging to the pipit genus Anthus in the family Motacillidae. It is also known as the grassveld pipit or grassland pipit. It was formerly lumped together with the Richard's, Australian, mountain and paddyfield pipits in a single species, Richard's pipit, but is now often treated as a species in its own right.
The buffy pipit is a species of bird in the Motacillidae family. It is found in plains and open countryside in southern and eastern Africa. The IUCN has assessed its conservation status as being of least concern.
