Ventured down to the Isle of Dogs on the Thames yesterday, hoping for better shots of the Ring-billed Gull. While waiting for the tide to drop I took a walk around Mudchute Park and Farm. I’d heard that Monk Parakeets had been reported here and soon heard them as a flock of six zipped over. Later I was surprised to find some birds adding to/repairing a large nest structure supporting several pairs, regularly flying in with small twigs. After observing these birds for an hour or so I think prefer them to the Ring-necked Parakeets… their calls are much less raucous and at least they are not competing with native hole-nesting species - they are the only parrot species to build an external structure! I’ll be back as it will take a bit of planning/luck to obtain some photos of these mobile exotics. Down on the Thames the Ring-billed Gull appeared late by which time the tide had dropped considerably and there was some nasty, low winter light to contend with - and you don't have much option while viewing from the Thames Pathway.
