The first sighting of some Swallows happened this morning at Bottisham Lock! Two of them were chasing one another at such speed - and after a long trip to get here too. I expect they are thinking of nesting behind the grill on Bottisham Sluice.
I had first sightings too of a Whitethroat and a Blackcap, affirming the beginning of Spring. Both lovely birds, full of song. Cherry Blossom, near the car, also heralds Springtime.
