Thanks to Wednesday's raptor success, I decided to revisit Argal again in the evening from 7-9pm for a short break. The birding was as expected, the usual 5 Great Crested Grebes, flock of Swallows, including the one Sand Martin and a fly-around Kingfisher. A Swift also flew through and as the light faded a bat sp. made a brief appearance. To round the evening off, a male Tawny Owl began calling around Chynoweth (a small hamlet north of Argal Reservoir).
