We have spent the last 4 days working in the Sunbury and Kempton Park areas of Middlesex. As we travelled along the motorway near High Wycombe on the M40, the sky became crowded with good numbers of Red Kite. Apart from the thousands of Gulls on the local reservoirs and flooded fields, the other birds you can't help seeing are dozens, if not hundreds of Rose-ringed Parakeets.
These charismatic birds are not difficult to find; you just have to listen and follow the raucous call to locate them.
