Kingfisher (possibly one of two) earlier today. It has recently been seen quite often in the wetland area in Compton Park.
The bird has a habit of perching on the fencing or the decking of the footbridge over the pond (as in the two smaller pictures) and seems fairly relaxed about the joggers, walkers and their dogs frequently passing by. It will fly off when a dog (main picture) or human gets too close, retreating to the reeds or a nearby tree.
To avoid disturbing the bird, I kept my distance, so it only shows as a tiny patch of blue and orange even in these cropped pictures.
