Although the sun was shining, it was a very cold day and I had frozen fingers after a few hours in the park. Here are some of the waterbirds I saw that day.
A couple of white Ross's geese on the bank stand out from the mega-crowd of Coots on the lake.
Here two Shelducks stand on the bank with a pigeon ball (it was washing) and Moorhen in the background.
This is another view of a Shelduck.
Here a Red-crested Pochard is liaising with a female Tufted duck.
The sun shone brightly on this Ruddy Shelduck, showing off it's white and green secondary feathers and black tail.
This Ruddy Shelduck was marching along the small stones at the edge of the lake.
A Barnacle goose was hoping for some food from the park's visitors.
These two Bahama Pintails were preening and cosying-up together.
This photograph shows the amazing difference in size between the tiny Hooded Merganser and a huge Greylag goose.
For me, no walk in the park would be complete without a sighting of at least a few of the eight black swans that now live there. I think that this is one of the original residents.
These three black swans are definitely part of the five that flew in from Hyde Park some time ago and have made St. James's Park their home. Note: the swan on the right is trying to bite the neck of the central swan - what a bad bird!
