Willet (or won’t it)
As colder weather begins to descend upon Calgary, it can be nice to reflect a little bit on some birds that we were familiar with during the summer months.
Many species of birds vary greatly from region to region. The Willet is one of these birds that are highly variable with two distinct subspecies, the eastern semipalmata darker, browner and thicker-billed than the western subspecies inornata that we see both in Calgary, and down here on the Gulf Coast.
A large shorebird with a flashy black-and-white wing pattern seen in flight, the willet was given its name thanks to its territorial call: pill-will-willet. A very vocal bird, the Willet, as biologist William Vogt wrote many years ago, has another call, a ringing kaaaty. When William Vogt studied a breeding pair of Willets back in 1938 he couldn’t help but call them Will and Kate, thanks to their calls.
Several years ago, before I was a big birder, I traveled out east for vacation. I observed my first Willet out there and now I have the chance to compare photographs of eastern and western Willets.
While the shots of the Western Willets are winter plumaged birds, you can still see the smaller size, darker color and stouter bill in the eastern Willet pictured above.
I always find regional variations in birds intriguing and the Willet is a bird with an easily visible difference, making it a good subject to view and compare from the east to the west.

Bird-brained
Who ever said birds were stupid? They were quite wrong. Many birds are quite intelligent and we get a fine chance to observe this intelligence in the migration of geese.
Everybody can associate geese flying in a ‘V’ formation with fall; the geese head south for the winter and are most often seen flying this way. Down here in Texas, we can often see Cattle Egrets flying this way, demonstrating their often overlooked wisdom. There is actually an intelligent method behind this flight, showing us that birds are smarter than we think.
Birds fly in a ‘V’ to save energy; by traveling this way, they render themselves as a group, more aerodynamic. If these birds were to fly in an unorganized group, flying would be a lot harder. Picture it this way; which car is more aerodynamic, a sports car or a dump truck? The sports car is by far the more aerodynamic of the two, its sleek form enabling it to reduce drag, therefore allowing it to go faster. When the geese and the egrets fly this way, they render themselves more aerodynamic, reducing the wind they have going against themselves and therefore applying less energy into flying. The bird flying at the point of the V though, has all the wind going against him, however this is not permanent. Studies have shown that after flying at the point for some time, upon becoming tired, the lead bird will drop to the back where flying is the easiest, and take a well-deserved break. This just goes to show that birds are a lot smarter than we think.
