Common Sandpiper

This Sandpiper is another busy little bird with a permanently bobbing tail & as for camouflage, surely one of the best? This is definitely one of my better efforts in terms of sharpness and clarity. Still handheld, but the bird was very obliging and was almost full frame at 500mm, which obviously makes all the difference! Still no 2x teleconverter, but it's arrival is imminent according to FotoMagic! I'm using my iPhone again but it thinks headphones are connected-when they aren't & the screen is displaying nasty water marks. May improve hopefully with time?
