The only time in my Swift records (1940-2010) when Western Australia reported more FTS than Central Australia (NT & SA) or Eastern Australia was the 1955/6 season, which was an El Nino year that brought much of WA its highest rainfall ever. (www.bom.gov/climate/ enso/ninacomp).

More recently - like this month we had an El Nino event that brought huge amounts of rain to Toowoomba, Brisbane, North coastal NSW, and Neville Schrader reported 50+ FTS flying very fast and very directly to the North over Parkes the day before Toowoomba had its downpour. Neville suggests that they were heading for this event.

I am wondering if any of you have observations that would support or contradict the concept that FTS are attracted to heavy rainfall events.

Looking forward to your ideas and your evidence.

Cheers & Happy birding
