Lake Vyrnwy

Had a great day at the Centenary hide yesterday. The pair of Little Grebes have successfully hatched two chicks who rode on the back of the adults. What was interesting to see was one of adults built a platform in the middle of the lake, away from the nest, for the chicks to go on to so they didn't get wet, which allowed both adults to dive under water and hunt for food. The Pied Flycatchers were busy building their nest with excellent views of both birds. The male Pied Flycatcher was singing all day long, but occasionally would add an extra four notes at the end (video below - might have to turn the volume up as its a bit quiet). I've not heard this before, so if anyone could shed some light on what it means that would be great. Also seen: Grey Wagtail, Mandarin, and Redstart.
