Heron colony vanishes into thin air
www.king5.com...
POINT ROBERTS, Wash. � Biologists checking in on one of the region's largest heron colonies discovered it was gone.
KING 5 captured video and showed it to Ann Eissinger, the foremost expert on the Point Roberts heron colony.
"The last time I went into the colony, it was quiet. Just the feeling I had was there was something seriously wrong here," she said.
To add to the mystery, Eissinger said just a few weeks earlier, the colony was its loud, active self.
"There were at least a hundred active pairs with young. We don't know what happened to them. The birds just disappeared," she said.
"Migratory birds have long been known to possess a magnetic compass that helps them find the correct direction during their migratory flights," said lead author of the study Thorsten Ritz, a physicist at the University of California, Irvine, in a press release.

You could be right, on the other hand the current shifting of the magnetic poles, I think, could be largely to blame.

No environmental cotastrophe about to happen. Environmental hazards take time. To put things into perspective "Day After Tommorow" could take several hundred years... and the buildup would be slow, not sudden...
The collapse of the Earth's magnetic field, which both guards the planet and guides many of its creatures, appears to have started in earnest about 150 years ago. The field's strength has waned 10 to 15 percent, and the deterioration has accelerated of late, increasing debate over whether it portends a reversal of the lines of magnetic force that normally envelop the Earth.
A reversal could knock out power grids, hurt astronauts and satellites, widen atmospheric ozone holes, send polar auroras flashing to the equator and confuse birds, fish and migratory animals that rely on the steadiness of the magnetic field as a navigation aid.
Although a total flip may be hundreds or thousands of years away, the rapid decline in magnetic strength is already damaging satellites.

I think your pelicans are splattered across asphalt roads in the Arizona desert there is another thread on here about that cuz they had mistaken the roads for lakes
