Slavonian Grebe - sun-flower


Slavonian Grebe (Podiceps auritus), Wilstone Reservoir, Nr Tring, Hertfordshire, 27/10/2012. The white of the cheeks extends round towards the back of the head and up into a notch at the top. Viewed in "original" size, you can see curve of the gape as it extends from the base of the bill up to the eye - on a Black-necked Grebe, this feature is straight rather than curved.
