Our first proper team outing of the year saw us dropping in to a couple of our sewage works sites: Carnon Downs and Gwennap. The day saw us catch just 38 birds, but this did include 17 Chiffchaffs and a scattering of Pied Wagtails, Meadow Pipits and 'others'. One of the others was a juvenile Robin that showed quite nicely how easy they can be to age sometimes.
Apologies for yet another poor iPhone photo
On this bird, note how the retained juvenile greater coverts (yellow in colour) show obvious 'thorns' that are longer towards to bird's body, whereas the moulted adult-type greater coverts (more orange in colour) have more limited 'thorns' which are more obvious on the outside of the feather tract. Simples!
Unfortunately we didn't catch the three Siberian Chiffchaffs on the two sites nor the Yellow-browed Warbler at Gwennap. Next time...
