Who is missing?

We are still searching our colonies of Yellow-eyed penguins and checking the nests. We are not expecting to find new nests unless they are in weird places (hope springs eternal). Now we are trying to work out who is missing by identifying the penguins still alive. This is not easy because they tend to run away when you approach them unless they are sitting on a nest. We will persevere and hope to find them in a box so we can read their transponder number. So far we have found only non-breeding males - which is to be expected. One of our colonies had 8 sitting round during the day. Their hope springs eternal as well. Maybe next year.....
Not sure who these two in the picture are. They came home after fishing and sat in the evening sun. In the background you can see some of our 17 "girls" - our mobile mowing machines courtesy of our neighbour farmer! We love them and thank you!
