Yes, the Merlin was in hot pursuit but at the last turn the BT turned right and the Merlin turned left and just kept going. I was kind of suprised the merlin did not go after the chicks.Did the Black Tern survived?

A herring gull in flight, I think the feathers look so soft. Super happy with my R5ii, shots come out super crisp with the 100-500

I mean soft as in mendable and soft to the touch (not stiff) - I don't mean soft as in not sharpIt's not always easy with white feathers But it's still a lovely shot.

My first thought is a shadow.What is the blue band on its right wing?
Nope, it's not a shadow. Looks like a plastic(?) band to me: check it at magnification, especially at the edge of the wing!My first thought is a shadow.





It is a shadow. Camera white balance pulls brightest details to be white. Those are in direct sun so contain red part of sun spectrum. White feathers in shade receive only diffuse light from sky that is predominantly blue.Nope, it's not a shadow.

Are you sure it is a shadow? The edges are very well-defined and you can see a triangular region of white at the bottom left of the blue band which you would think would also be in shadow.

Any shade on white or gray is of opposite colour balance to the light source. Just look at old school watercolour masters, J.W.M. Turner conveyed the warmth of the scene by fooling our eyes by cool blue tones in shades.

I am thinking of the Blue Riband of the Atlantic for the fastes gull.My mind then jumps to kinesio tape for hard working gulls.
