He has assigned himself the job of watching over the Swan nest. He is always there.
His mate is there also, often just out of the picture.
His work comes first, she knew that when she got involved with him.
He chases the interlopers away. Who did they think they were?
It won't be for a few of weeks.
We can wait easier knowing the duck is on duty.
Here is a whole set of pictures of the Swan nest in the city http://www.flickr.com/photos/chloe-and-ivan/sets/72157629250352920/ ♥Chloe
