Tree Pipit
Anthus trivialis
This is a small pipit that resembles the meadow pipit. It is an undistinguished looking species, with brown stripes above and with black markings on white underparts and buff breast below. It can be differentiated from the slightly smaller meadow pipit by its heavier bill and greater contrast between its buff breast and white belly. Tree pipits are more likely to perch in trees. The call is a strong spek, unlike the weak call of its relative. The song flight is unmistakable.

Water Pipit
Anthus spinoletta
The water pipit is 15–17 centimetres (5.9–6.7 in) long and weighs 18.7–23 grams (0.66–0.81 oz). The adult of the nominate race in spring plumage has greyish-brown upperparts, weakly streaked with darker brown, and pale pink-buff underparts fading to whitish on the lower belly. There may be some faint streaking on the breast and flanks. The head is grey with a broad white supercilium. The outer tail feathers are white, and the legs, bill and iris are dark brown or blackish. In non-breeding plumage, the head is grey-brown and the supercilium is less distinct. Voice: The water pipit's song is delivered from a perch or in flight, and consists of four or five blocks, each consisting of about half a dozen repetitions of a different short note. In comparison, the European rock pipit's song is a sequence of about twenty tinkling cheepa notes followed by a rising series of thin gee calls, and finishing with a short trill.
