Phylloscopus collybita collybita
“By far the most numerous of our summer visitors, and is greatly in excess of the Willow Warbler” – Mathew, who quotes Dix as saying that in the north-east of the county it is “about equal in number to the willow warbler”. Dix is right; but for the rest of the county the Chiffchaff predominates. Mathew says a few remain throughout the winter, and this is the case to-day, in mild winters. On passage through the islands, this species is much less numerous than the Willow-Warblers. Usually arrives first week in March.
