Tree Pipit Anthus trivialis breeds Great Britain and Iberia to eastern Siberia, with schlueteri in Tianshan and Altai in Xinjiang. ID & COMPARISON In morphology, voice, and habits, very much like Olive-backed Pipit A. hodgsoni. Crown and mantle brownish-tinged, not greenish-tinged as Olive-backed, and more distinctly streaked. Tree Pipit has less prominent, duller supercilium, with no black border above, and Tree Pipit lacks Olive-backed’s pair of spots, one black and one creamy white, at rear of ear coverts. Also very similar to Meadow Pipit A. pratensis, but Tree has stealthier gait and more prominent supercilium, Tree contrasts more below (having a buffish breast and whiter belly), Tree has flank streaks that are obviously narrower than its breast streaks, and Tree is more likely to be found in forests. BARE PARTS Bill brown above, pink below; feet pink. VOICE Highly variable song includes rapid, finch-like trills; call a short, high-pitched, single-note tseep, distinctly harsher than Meadow Pipit and very much like Olive-backed Pipit, but call of latter slightly thinner, higher-pitched, and less slurry. — Craig Brelsford
