Wilstone Reservoir - 21.4.15

Just after 10am news broke of 2 Little Gulls on Marsworth followed an hour or so later of 2 Black Tern and 10 Little Gull on Wilstone. I left work and headed straight there and immediately picked out the 2 Black Tern and 8 adult summer plumaged Little Gulls. I walked to the jetty for better views but they had taken off and then spent the next 10 minutes flying over the water before heading off to Marsworth! Also seen were 3 Egyptian Geese, Oystercatcher and my first female Blackcap of the year.
