I visited Martin Mere twice in March and in the resident collection of birds from around the world there is a pair of Coscoroba Swans, a species native to South America. It is the smallest variety of swan although is larger than most geese, and I think it is a very good looking bird. The female was (as you can see) on the nest, and the male was dutifully patrolling the perimeter warding off any potential threats. He was quite aggressive and I definitely didn't want to get too close. He seemed quite grumpy and bad tempered but I guess you could argue that he was taking his role very seriously and doing his best to protect his future family.
Although unrelated I have included an extra image below, this time of a Moorhen also sat on its nest. It is that time of year and I look forward to seeing lots of new life as spring really gets under way.
