He was having a little sing, first time I've heard one make a noise, I did a bit of a Google for Jay sounds, though none sounded like what I'd heard, but apparently they also mimic other bird noises. The sound I heard was closer to wood pigeons cooing.
I've been watching this Black-headed Gull on the river at Whalley, it seems to prefer this method of fishing - and very successful too. There's a little tell tale sign, a twitch of it's tail, just before it launches upwards, but obviously totally random to get it with it's beak just touching the water. It also has the ability to swim backwards, another thing it does is to waggle it's feet, you can see the ripples but it's not moving, so I'm assuming it's maybe trying to disturb the fish that are motionless.
nice photos, I always miss the Reed Warblers a case the time I have focus there gone lol. Although I have just got the software to my lens and has an option to increase the speed of it. so who knows tomorrow.
