I have been watching the falcons this morning and Mum spent a lot of time trying to herd the chicks into the nest so she could shade them with her wings. The chicks kept trying to escape down to the other end of the ledge so they could get into some actual shade. Eventually all three managed to get away, but she stubbornly stayed keeping the empty nest as shaded as she could. She’s finally given up and flown off now and the chicks are all enjoying the shade.
