I had to make a trip up to Horsham today and with an hour to spare I thought I would call into Warnham LNR for a quick look. I wasn't expecting too much and that is exactly what I found. Wanham is a site to visit in the winter if you are looking for birds, although it can be worth a visit in the summer for butterflies and dragonflies.
Fortunately there were two Kingfishers mobile around the site. It was difficult to get a clear shot but I did manage the one below. The bird was mostly in shade which gave me a chance to get the iridescent blue colour along its back. This is usually too bright for the camera to record when it is in direct sunlight.
Actually the feathers are a dull brown rather than blue but the structure of the feathers scatters and reflects the short wavelength blue light much more than the longer wavelength red light thus giving the bright blue effect. So to be correct I should be referring to it as the "Tyndall Effect" rather than iridescence.
And a few shots taken at Pagham North Wall the day before.
