Great spotted woodpecker: usually out of sight amidst the leaves so green;
Sanderlings, chasing the breaking ripples on the shore, pouncing on tasty morsels. See the RSPB site: http://www.rspb.org.uk/discoverandenjoynature/discoverandlearn/birdguide/name/s/sanderling/index.aspx .
I cherish the time I introduced these little creatures to a class of tough 10 and 11 year olds, who filled up with joyful laughter at their performance, dashing in and out of the water on Broadstairs beach. Thank you, Andrew,for setting us all off!
