So what ornithological event marks the arrival of Spring? Cuckoo, first Swallow? Apparently the Hoopoe is also an advanced messenger. Well, they're all here.
But nobody told the Redstart who has decided to squat belligerently in one of the Swallows' nests in the wood shed. She is just sitting in there, fluffing up the hard edges of the old nest while the Swallows, fly in, flutter round screaming. A definite look on her face which says "go on, make me".
