Phylloscopus collybita
The Common Chiffchaff (*Phylloscopus collybita*) is a quintessential Old World warbler, small and subtly plumaged, typically measuring 10-12 cm in length with a wingspan of 15-21 cm and weighing 6-9 grams. Its plumage is generally drab, featuring olive-brown upperparts, whitish underparts with a yellowish wash, a pale supercilium, and notably dark legs, a key field mark distinguishing it from the similar Willow Warbler. Belonging to the family Phylloscopidae, it is closely related to other le...
This adaptable warbler primarily inhabits open deciduous or mixed woodlands, scrublands, parks, and gardens, favoring areas with undergrowth. It is found from sea level up to mid-montane elevations, typically below 2,000 meters.
Their diet consists almost exclusively of small insects and spiders, gleaned from foliage or caught in flight. Occasionally, especially in autumn, they may consume small berries or nectar.

They employ a 'gleaning' foraging strategy, picking small insects from leaves and twigs, and also engage in aerial fly-catching with short, quick sallies. Males are highly territorial dur...
The Common Chiffchaff has an extensive breeding range spanning much of Europe and temperate Asia, from the British Isles across Fennoscandia, Central Europe, and Russia, eastward to eastern Siberia and into China. Its wintering grounds are similarly widespread, covering Southern Europe, North Afr...
