When I chanced upon and illustrated this ballet clip, I was already thinking about courtship through dance. In late April I observed the final act of the ritual between a pair of mating grebes, but looking at the birding websites, I think the dancing had gone on through March.
A couple of weeks ago, I found myself opposite a grebe nest with two chicks and remaining eggs unhatched.
The male returned periodically and fed the chicks with feathers. In so far as I can tell, this serves as a stomach lining, protecting against the sharp chitinous exoskeletons in the infant diet. The chicks took frequent outings on the mother’s back or struggled to hide beneath her wings when she was sitting.
The following week, they had all moved on.
I have illustrated grebes previously.
