Another post work visit this evening and another migrant in the shape of two Sand Martins found by Marco Johnson, which is as far as I can ascertain, the earliest date for this species in the lower Lea; these birds are almost certainly one of the breeding pairs from last year or their offspring, as at least one of them went to roost in the breeding pipe in the lock wall (LVRP has provided a multi-storey purpose-built des-res Sand Martin wall at Bow Creek but these idiotic creatures prefer to raise their children in an overflow pipe how ungrateful is that?). The two Little Ringed Plovers were still on the basin, six Shelduck were scattered throughout the site with single Redshank and Common Sandpiper at Bow Creek; Teal numbers seem to have dropped dramatically overnight with an extensive search producing just 27 birds.
