Black Stork juv

Spurn August 4th -- often standing where you are told means you are a long way off and other people get closer shots but hey ho that's the problem with doing the right thing -- 500 with 2x on 7D2 -- noise is still a problem with this camera even at 800 ISO -- its habit of putting its bill in its neck feathers was a bit odd looking; people with long memories may remember an ongoing debate in British Birds about Black Storks with white tails, which was of course people seeing displaying birds with white undertail coverts overlapping the upper tail -- not sure why this one had these white feathers raised up over its back when it was walking in the juncus?
