Started the day with a walk round the Caldecote patch. The stubble and winter wheat held large numbers of Skylarks and Thrushes with a few Reed Buntings and Linnets in the hedges. The highlight though was a Merlin being mobbed by a crow before getting bored with the attention and disappearing in the direction of Woodford Lane. Near the river there were even more Thrushes, 4 species in fact and a 50+ flock of Linnets. On the return leg along the flood plain was a Stonechat.
