Note: Both Chiffchaff and Blackcap birds present from early January 2016. It is difficult to ascertain whether singing birds are freshly returned migrants or just over-wintering birds stirred into performing by favourable weather conditions. One incidence of a ‘pollinated’ Chiffchaff has been recorded – which may be a more reliable sign of a recently returned migrant from the Mediterranean basin.
