Day 24: Facial pattern more evident

June 5, 2017 in In the Nest Box

2017.0605-001By day 24 the facial pattern behind the eyes is becoming increasingly evident, and some colouration is becoming visible on the upper breast as juvenile feathers develop beneath the down.   The legs are now just about fully developed, and thus banding takes place now or a few days before.  

It is fascinating to have this awesome opportunity to watch the growth and development of the chicks inside the nest box.  Here the female has brought back prey and grips it tight with her oversized left leg talons!
