Greylag Geese

I drove over to Leighton Moss this morning with the idea of visiting the outlying hides to see the avocets however, on arrival, I found the access closed off as the very high spring tide was expected to inundate the car park.  I returned to the main car park and walked to the Causeway Hide instead.  A Bittern was booming in the distance and a Cetti's Warbler was singing very loudly from a bush at one end of the hide but my blip today is these two Greylag Geese flying very low and in tight formation.
