The ringing of the Nest 1 chick took place nearly a week ago now, and it won’t be long before she flies. Our ornithologist takes measurements which allow him to form a view on the gender. The chick weighed a very substantial 1730g; analyses show the average female at ringing is 1500-1600g, the male 1200-1400g. The Nest 1 chick was a little older at ringing – nearly 7 weeks – than the 6 week norm, but even so it seems probable she is a pretty heavy girl! Females legs are thicker than those of the male bird, and although she had no siblings remaining for comparison, her legs are sturdy. Her wing length too was longer than an average male.
The Kielder Water and Forest Park’s Facebook page sought ideas for a name for her and Olympia proved the most popular.
