Alternative name: Eurasian Chiffchaff
- Phylloscopus collybita
Includes: Siberian Chiffchaff
10-12 cm (4-4¾ in)
- Greenish olive-brown upperparts
- Off-white underpart
- Yellowish flanks
- Short white supercilium
- Fine dark bill and legs - but beware of recording willow warbler's legs as dark when they are in shadow.
- Constantly dips tail when moving around in foliage.
Six subspecies are recognized:
- P. c. abietinus:
- P. c. collybita:
- P. c. brevirostris:
- Highlands of western Turkey and Black Sea coastlands of northern Turkey
- P. c. caucasicus:
- East of range of brevirostris at lower elevations south to Armenia
- P. c. menzbieri:
- P. c. tristis:
Tristis is sometimes accepted as full species, called Siberian Chiffchaff.
Open woodlands, tall trees are required for singing in the breeding season. Low shrubs, brambles etc for nesting.
Flicks tail, downwards (this habit is not seen in Willow Warbler).
The female builds a domed nest with a side entrance, made from dead leaves and grass. Two to seven cream eggs with reddish-purple or blackish spots, are laid and incubated by the female for 13–14 days; the female cares for the young for about two weeks until they fledge.
The diet includes insects.
Song: the most reliable way to distinguish from Willow Warbler. It sings its name chiff chaff, chiff chaff, though sometimes mixes up to chiff chiff, chaff, chaff.
Call: a soft wheett
It sounds at first like a tristis but is much too downslurred and not flat enough.
