Goldeneye - Ogston Reservoir

Very windy and heavily overcast all day making it difficult to stand, never mind look through binoculars particularly on the moor, so made another visit to Ogston. 
Nothing new on the reservoir but a Goldeneye came reasonably close inshore and a second bird flew past. I put them both in the log as female/ immature but looking at the photos the top bird is an immature with all dark bill and largely grey wing coverts whilst the inset photo of the second bird is an adult female with yellow tipped bill, brighter yellow iris and white wing coverts.
