Beryl as well as feeding her 2 chicks was seen about 4 days ago standing on the edge of the nest looking down.
Every now and then she would lean in and hammer away at something.
And yes I was right she now has 3 chicks. Congratulations on a personal best.
Today more hammering so we shall see if she is going for 4.
Notice how the adult landing on the nest triggers the automatic “heads up, beak open’ response.
