The Asian Rosy Finch flock I saw at the end of last year was still on the coast but its numbers had greatly thinned. At first we could only find one (the above male) so I took a walk on the nearby grassland (changing from the 500 f/4 used above to the 600 f/11)…
There was the grand total of ONE Common Redpoll (plus a few gulls and crows). Luckily the redpoll was tame.
The 600 f/11 is a viable lens in such bright conditions.
