Skylark (Alauda arvensis)
Savi's Warbler (Locustella luscinioides)
Short foldable crest. Pale eye-ring and supercilium. Long primary projection (primaries extend well beyond tertials), white trailing edge to wing and white outer tail feathers. Tail much longer than in Wood Lark.
Sound:Song a pleasing energetic stream of chirping, merry trills, interspersed with mimicry. Trills quite resonant with fairly full tone. Song usually given in flight high in the air. Less characteristic, shorter, weaker and more varied song when given from ground. Most typical flight call a short trilling "chirrup", with the end note noticeably lower pitched than the start. Also several other more cryptic calls.

CCReedbed-living, dull coloured warbler with fan-shaped tail. Under tail coverts lacking pale fringes or markings. Vague and short supercilium. Differs from other locustella by unstreaked chest, back and under tail coverts. From Reed Warbler and Marsh Warbler by very long and buff under tail coverts, smaller head and pinkish legs.
Sound:Song insect-like and high-pitched. A monotonous stream of even clicks similar to the whirring of a sewing machine. Song most similar to Grasshopper Warbler but faster (each click hard to distinguish), and lower pitched with less, ringing quality, due to less prominent high frequencies. At closer range a Robin-like, accelerating ticking is heard, introducing the actual song.
