Fork-tailed Swifts & storm fronts/heavy rain events.

Yes I am getting old; of course it is La Nina and not El Nino. Thanks Mike Carter for waking me up. I well remember measuring and weighing swiftlet nestlings six days a week throughout the dry heat of the 1986/7 El Nino season at Chillagoe. It was so dry that some of the nests came unstuck and fell off the cave roof and parent s got so little food that many nestlings died.
