The chicks are getting so big!! They have started to destroy the nest slightly as they are wiggling about and stretching their wings.
Lady and Old Blue are doing an excellent job of bringing them lots of food, especially caterpillars. Although the one that Old Blue has brought back in the clip below is so big it hardly fits in their mouths. He has quite a bit of difficulty getting them to take it.
To tell the difference between the two, Old Blue always feeds from the bottom of the nest nearest to the camera. Lady goes to the far side of the nest; she also has a wider band across her eyes and feeds the chicks much quicker.
