It appears as though the chicks hatched either the night of the 13th or early on the 14th of April. I observed two feeding occasions on the afternoon of the 14th and a friend who lives close by observed the same earlier in the morning. I did not see prey flown into the nest on two visits by the male and a nest duty swap., so whatever they were using as a food source had been brought in previously. The female also fed herself in the nest which the first time I've observed this. Hopefully, it wasn't an eaglet?
