Here's the ravine at the beginning of the week: Blackthorn in flower; fresh, bright new leaves on the Hawthorn; Sallow in flower etc. More to the point what's skulking in there? Well today, at least 3 Blackcaps (one of which was singing). Overhead Sand Martin and Swallow and cruising for a bruising Sproghawk and Kestrel (a very infrequent visitor here) as well as Magpie and Carrion Crow.
No sooner do I proclaim the Shags have gone and the Kittiwakes are everywhere and there are Shags everywhere and Kittiwakes are absent (but for 2). Let's try "There's no hope of a Greenish Warbler and Bluethroat is a mythical beast".
