Anyone come across similar incidents in our southern climes?

Re: Bird deaths in the far far north
It's hardly surprising that birds in places with extreme climates should have higher weather-related mortality than birds in more temperate climes. This survey covers 33 years of field work and there's no indication in this report that these causes of death are becoming more frequent.
Global weather is largely driven by the temperature differences between the poles and the equator, and since the Arctic has been warming more than the rest of the world in recent decades the models predict that if anything storminess should decline in the northern hemisphere (the South Pole on the other hand has cooled slightly in the last 50 years, so things may be different down this way). A warmer Arctic may adversely affect the birds in other ways, such as changing patterns of food availability, but it's unlikely to lead directly to more weather-related deaths.
