Thanks Merv,
I am a doom- monger so I nearly posted the pic of dead pied fly in great tit box with dead newly hatched young great tits! I have often found 'double-decked' nests in this wood with tits eggs, young and even adult skeletons trapped underneath the pied nest so perhaps the alpha pied male got his in the end tho' it was lose/lose as the great tit lost its young also. Ironically this year there are empty boxes nearby.
6pm today my last unmated male pied sung his last phrase; he has sung all day since 18th April and just this morning was on top of the box he was 'saving' for the female who has never showed up. Coming to a wood near you, one very fed-up boy.
Moorhen with large chick on boardwalk pond Cors Caron this morning, amazing considering the predator pressure...and the un-leashed dogs. Elsewhere on the bog, 8 adult Canadas with 15 chicks of varying sizes. Other years no Canada has been seen to keep a chick!
