Tree Pipit

The tree pipit is a small, streaked passerine with brown-striped upperparts, black markings on the white underparts and a buff breast contrasting with a whiter belly. It resembles the meadow pipit, but has a heavier bill and a stronger division between the breast and belly colours. It also perches in trees more readily. Its forceful call and display flight help identification: a singing bird rises from a tree and then parachutes down on stiff wings. (Wikipedia, tree pipit account)

Tree pipits breed in open woodland and scrub, placing their nests on the ground and laying four to six eggs. They feed on insects but also eat seeds. The species is a long-distance migrant, nesting across much of Europe and eastward through the Palearctic, then wintering in Africa and southern Asia. The nominate subspecies breeds through south-central Siberia, Mongolia and northwest China, making the Mongolian records consistent with a documented breeding range rather than an inferred regional occurrence.
