Dryoptera

Blue tit nest part 3

In the header photograph, the blue tit’s eggs are lying in a cup shaped nest lined with soft feathers that are obviously intended to keep the eggs warm. But around the edge of the cup there are larger feathers; their purpose is not so clear.

Blue tit nest part 2

After yesterday’s video post, a reader asked what triggered the blue tit female (it is always the female blue tit that builds the nest) to stop collecting moss and to begin collecting what he called fluffy stuff. While failing entirely to find an answer to his question, I found a treasure trove of research into blue tit nests and the materials they use to build them.
