Welcome to Weirdbeautiful!

Today's links are definitely weird, rather than beautiful.

In recent days there have been 3 separate incidents of mass wildlife deaths that are as yet not fully explained.

The first was [this story] about the mysterious death of more than 1000 Red-winged blackbirds(Agelaius phoeniceus) on New Year's Eve in Beebe, Arkansas. The birds apparently fell, dead, from the sky over the small town in White County.

The second was a similar, also unexplained, instance of around 500 birds- mostly blackbirds and other small to medium sized birds- falling from the sky in Louisiana, around 30 miles from Baton Rouge and around 300 miles from Beebe, Arkinsas.

The third was the finding of two million (mostly juvenile) dead fish off the coast of Maryland. The most likely explanation for this event is currently considered to be that the fish were killed by "heat shock" caused by the rapid and large temperature changes over the past few weeks.
