Pulborough Brooks today; full of bird song.

A mallard had already hatched her chicks on Pulborough Brooks today.

A grey heron might pose a threat to young ducklings. 

It was the bird song that was so memorable on this 9 miles walk though; chiffchaffs, greenfinches, tits, nuthatch, various woodpeckers, dunnocks, blackcaps, skylarks and above all robins.
There were scores of Canadian geese and lots of Shelducks plus some remnants of winter visiting ducks.
As I was leading the walk from the Mid Sussex Ramblers programme, there was limited time to pause to photograph more.  We saw a kestral hovering but not the falcon that was here the last time we were here in January.
