Morfa Berwig Nest Box project update Wednesday 16th May 2018
I have been monitoring the 44 nest boxes at Morfa Berwig since the beginning of April, there have been signs of activity in 49% of the boxes, however todays update perhaps presents a better idea of the breeding season so far. The cold nights in the past week have taken their toll on one box where all seven well grown Great Tit chicks have perished. It seems that a predator, probably a Weasel, has finished off two clutches of eggs. On the brighter side I did manage to ring three great tit chicks, albeit there were originally eight eggs in the clutch. NEST BOX NUMBER ACTIVITY RECORDED Species 3 Female incubating NB not counted Blue Tit 4 Female incubating NB not counted Great Tit 6 Nest deserted, all seven chicks dead Great Tit 9 Nine eggs warm Great Tit 11 Female incubating NB not counted Blue Tit 16
