This is meadow buttercup. It made me think of when we used to hold buttercups underneath the chin to see if it reflected yellow, if it did it meant you liked butter. A scientist has revealed that it's something about the pigment and surface of the flower that always reflects yellow on people's skin but I think that's just spoiling the game.
We went to the RSPB reserve at Burton Mere today, there was so much wildlife to see and photograph we were there for hours. We saw 3 spoonbill, 9 little egrets, avocets and their chicks (the warden counted 76 of them yesterday), a sedge warbler (spotted with a bit of assistance from some really helpful guys who pointed it out to us) shoveller ducks and 9 ducklings, 2 families of canada geese, one with 3 goslings and the other with 5, swans and 4 cygnets, lots of black tailed godwits, black headed gulls and chicks, lapwings and chicks, oyster catcher, red damselfly, blue tail damselfly and a toad which I nearly stood on when it hopped out onto the path in front of me! Lots of wild flowers as well, so often buttercups are in full sunshine and difficult to photograph (probably because of what that scientist discovered) but I thought these looked lovely in the shade.
