The Mad Ratters Tea Party  - Work on the largest (ever) programme to eradicate rats and mice from South Georgia is falling behind the planned schedule as continued windy weather in target areas towards the northern end of the Island is preventing the helicopters from baiting.    Throughout March 2013 unrelenting winds have kept the baiters waiting, sometimes as long as ten days, for a chance to work.     Despite the poor weather, the baiters have already completed three complete Baiting Zones, and almost exactly half of the rat infested land area targeted for this season.      In just three hours of baiting, with all three helicopters working, they can remove rats from 28 square miles of land.     The helicopters cannot spread bait safely and accurately with more than a moderate wind speed, so weather forecast charts and weather reports from the field parties put out to watch for breaks in the weather are eagerly analysed in search of elusive patches of slow-moving air.
