June is the time of winsor blue skies.
A time of summer migrants
like cuckoos and sedge warblers . . .
. . . and the house martins.
At low tide they dive down to pick up beakfuls of oozingly sticky mud for nest building.
It is not just the mud they come for . . .
. . . there is the dazzlingly green algae growing on the lock walls.
They approach at speed
grab onto the vertical face
like some superhero defying gravity
and pick off algae
to bind into their mud nests.
