Hilfield Reservoir - 15.4.18

I was going to head up to Wilstone for a pair of Black-necked Grebe and some Little Gulls but with a possible Glaucous Gull at Hilfield I decided to pay a visit there instead. I arrived to find Steve Murray and Tony Blake on the dam but the possible Glauc had flown soon after it arrived. The visit wasn't a total loss as there were 6 Little Gulls showing nicely and the same number of Black-necked Grebe. 3 House Martins were also a year tick.
