It’s a familiar sight this time of year: enormous flocks of snow geese, covering a field, then all taking flight at once, whirling and swirling in unison. It’s almost like they’re all under the control of a single mind, but of course they aren’t. In fact, they’re under the control of a multitude of minds, all of them, literally, bird brains. So how do they move in synchronicity?
Despite years of study, the phenomenon, well-known though it is, has remained a puzzle to researchers. Explanations have included telepathy (no, seriously, that was a suggestion floated in the 1930s). But it appears the actual explanation is more mundane, though ...

Here’s another column drawn from one of the chapters of my new book
Disease-Hunting Scientist (Enslow Publishers):
Every spring, an estimated six million birds arrive in Alaska to breed. Some spent the winter in Southeast Asia, home to a strain of avian influenza called H5N1.
Although swine flu is getting all the attention right now, bird flu hasn’t gone away: many scientists fear it could someday become more readily transmissible between humans, and produce a deadly global pandemic.
Even in its current form, it has already sickened 433 people worldwide, killing 262 of those. At the back of everyone’s mind is the 1918 pandemic that killed an estimated 50 million people, many of them healthy young adults—a pandemic caused by a ...

...is how
this story about Madagascarian insect life is headlined, but never mind the science: doesn't "Moths drink the tears of sleeping birds..." sound like the start to a wonderfully evocative poem by some terribly sensitive poet? Something like:Moths drink the tearsOf sleeping birds;I drink up beersAnd slur my words.*Sniff.* Brings a lump to your throat, doesn' it?**Why, yes, I am procrastinating this morning. How could you tell?

Canada Geese are among the most identifiable birds on the prairies, but we tend to have a love-hate relationship with them. We love to see and hear them honking overhead on a quiet autumn evening--but we hate what they do to our parks, lawns and golf courses.
But if you think today's geese are a nuisance, consider: last week Australian scientists reported the discovery of a prehistoric goose that weighed 500 kilograms. Before we get to the details, some background on the Canada goose of today.
There are several subspecies of Canada goose, characterized by variations in size and shading, ranging from the Giant Canada Goose (the kind we have in Wascana Park), which can have ...
