IDENTIFICATION Water Pipit (spinoletta) in non-breeding plumage The following table only outlines the features useful in the separation of spinoletta and littoralis in non-breeding plumage.
Above: Water Pipit (spinoletta), Getteron, Halland, Sweden (Stephan Johansson). The mantle is clearly warm brownish although on this individual the head is becoming markedly greyer (and thus contrasting with the mantle), note also the very pale, whitish underparts, importantly including rear flanks and underpart streaking that is not only 'sparser' than that of Rock Pipit but is clearly smaller, narrower and more clearly defined. The malar stripe is poorly defined here and partially broken.
Above: Water Pipit (spinoletta, same individual as immediately above), Getteron, Halland, Sweden (Stephan Johansson). The brownness of the upperparts is obvious here as is the contrast to the greyish head.
Above: Water Pipit (spinoletta, left) and Meadow Pipit (Anthus pratensis, right), Getteron, Halland, Sweden (Stephan Johansson). The underpart streaking of this individual is fairly classic, although the apparent diffuseness on the flanks is more due to the 'fluffing out' of the feathers. This aside, the streaks are clearly defined and the belly is reasonably unstreaked, also note how brown the upperparts are and compare them to those of the Meadow Pipit. In this individual the malar stripe is again typically poorly marked and does not reach the base of the bill.
Above: Water Pipit (spinoletta, same individual as Fig.), Getteron, Halland, Sweden (Stephan Johansson). Note how the rump is obviously warm brown and on this individual at least, concolourous with the rest of the upperparts, which are also rather inconspicuously streaked.
Above: Water Pipit (spinoletta), Getteron, Halland, Sweden (Stephan Johansson). An interesting bird due to the leucism across the forehead (also present on the rear of the crown) and throat. The underpart streaking however is typical, with very fine and well defined flank streaks against a very pale, whitish ground colour across the entire underparts.
Above: Water Pipit (spinoletta), Queen Mother Reservoir, London, 23.10.03 (Jerry O'Brian). Rather warm brown, apparently unstreaked upperparts, bold supercilium, two fairly obvious white wing bars, whitish underparts with rather sparse, fine, well defined streaks, and a poorly marked malar stripe, all in all an absolute classic example of a non-breeding plumaged Water Pipit.
Above: 'Eastern' Water Pipit (coutelli), Bahrain (Adrian John Drummond-Hill). Whilst subtle differences exist between the sub species coutelli and spinoletta Water Pipits (not featured within the scope of this article), this bird still exhibits classic features existing in both, particularly here the fine and defined underpart streaking and large white supercilium, note also this bird has already dropped a couple of tertials leaving only the longest present.
Above: Non-breeding plumaged Water Pipits (spinoletta). Notice the very pale, whitish ground colour of the underparts and the restricted, rather fine, distinct and sharply edged streaking on the breast, with fine, 'pencil streaking' on the flanks. The outer-tail feathers (P6) shows a large and conspicuous area of white, especially on the inner webs. (Ian McKerchar)
Above: Non-breeding plumaged Water Pipits (left two, spinoletta) and Rock Pipits (right two, littoralis/petrosus). The difference in the shape, clarity and distribution of streaking on the underparts between the Water and Rock Pipits is immediately obvious, whilst the ground colour to the underparts of the Water Pipits are clearly paler and the white. Note again the large and conspicuous white wedges on the inner webs of the outer-tail feathers on the Water Pipits . (Ian McKerchar)
Above: Non-breeding plumaged Water Pipit (left, spinoletta) and Rock Pipit (right, petrosus). The much warmer brown upperparts, including very importantly the back, rump and upper-tail coverts on the Water Pipit are obvious, whilst this Rock Pipit's (a specimen from St.Kilda) are rather greyish/olive with quite large and distinct streaking. Note the quite buffish outer-tail feathers on this particular Rock Pipit. (Ian McKerchar)
Above: Water Pipit (left, spinoletta) and Scandinavian Rock Pipit (right, littoralis). The outer-tail feather (P6) of the spinoletta appears white on both webs and the second-to-outer feather (P5) displays the large and characteristic clear white 'wedge' on the inner web and a small whitish tip to the outer web but to be fair, P6 on the littoralis also appears similarly as white (albeit with a slightly more greyish-white outer web) but T5 typically has an all brownish tip to the outer web and very little paler wedge on the inner web. In the field though, on a live bird jumping and hopping about, could you differentiate them with sufficient certainty? (Ian McKerchar)
