When I saw this pic I knew it had to be saved for today :)
I think the boring correct name is Tapetum lucidum, the reflective layer on the back of eye.
Sometimes we have to let the mystery of life become part of our lives
A lot of coot families at The Groynes at the moment ranging from adults still on eggs (like this one) through to birds with several week old chicks in tow. In the picture the bird had built a nest in the middle of the pond right out in the open, no cover from aerial predators at all.
A small group of warou (welcome swallow) were hawking over the 'kayak pond' at the groynes and using a harakeke stalk as a resting spot. A lot of busy preening going on. I expected to perhaps see fledged youngsters already but all of the birds seen were mature adults in "fresh" basic plumage for breeding.
