If you see this man with binoculars looking towards the roof of your house, all is well, he's not casing the joint!
This is Chris Orsman from the RSPB on his now weekly survey of House Sparrows in the Cliffview Road area. Chris is a key member of the London House Sparrow Project team which, until recently, surveyed 66 sites across London on a roughly monthly basis. The number of sites has now been reduced to permit weekly visits to the more active sites - including ours.
Chris will be in Hilly Fields park peering into our gardens and also in one or two gardens in Cliffview Road.
Some of his visits may be quite early in the morning but most surveys in our area will be on Wednesdays.
