Willow warbler bird is a small, slim warbler, restless and active. Most similar to the Chiffchaff, but at all ages can be told by its pinkish-brown legs. It is greyish-green with a hint of brown on the upperparts, the underparts are whitish with a pale yellow wash on the throat and breast. The face is well marked, with a long, pale yellow supercilium and a well-defined dark eyestripe. The wings show quite a long primary projection, giving it a slightly elongated shape. Immatures in autumn are suffused with a brighter yellow on the whole of the underparts and face.
Willow warbler bird is a common summer visitor, found in a wide variety of bushy habitats. It can be found in open woodland, both deciduous and coniferous, birch forest, willow scrub, heaths, commons, plantations, parks, large gardens, indeed virtually anywhere with shrubs and small trees. Its range extends right up to the higher latitudes and beyond the Arctic Circle.
The call of willow warbler bird is a rather soft, plaintive, enquiring, disyllabic and upslurred "hoo-eet", the second syllable higher than the first. It can also give a more monotone "hwuu" version of the call when anxious, and a repeated nasal scolding "chwherr" when alarmed near the nest, not unlike a Sylvia warbler. The song is a pleasing cadence of simple whistles descending through the scales, such as "svi'svi'svi'svi tue-tue-tue-tuee hweh-hweh-hweeo-hweo-hweo hi'hi-hiwe'oo". The initial 3-4 notes are slightly faster, sharper and higher, followed by 8-10 notes which are given quite strongly and descend the scale in steps. The final notes sound weaker and more stifled, tailing off at the end (although this is variable). The song generally lasts for 2-3 seconds or in longer phrases of up to 4.5 seconds.
