Derby Peregrines: 25 days old















In their fourth week of life, the chicks undergo significant changes almost daily. Around day 25, the brown tips to the secondaries become clearly visible, and the number of coloured feathers visible on the breast increases noticeably. Behaviourally, they are rarely resting on their tarsi anymore at this age.
