The Conscience of a Birder

By

Well, rats.

As the breathless tone of yesterday’s entry reveals, I was excited yesterday morning at Jericho Park to find the bird above, which I gleefully ticked off as a Western Gull–or something very, very close to it.

As I pondered, though, the pale eye and, especially, the orange tint to the orbital ring started to worry me. I sent the photos off to a couple of friends with massively more expertise and experience than I’ll ever have with these birds, and the answers came in: Steve said he would have called it a hybrid “but who can really tell,” and Guy agreed, noting among other things that the mantle was too pale even for northern occidentalis.

So this one goes down as a dark hybrid or introgressant, and my search for a pure Western Gull in British Columbia continues.

I now read a different meaning into the bird’s posture.

Good for you, Rick. Adhering to your own rules shows great integrity.

You mean there’s such a thing as a pure Western Gull? ;) This isn’t a great time of year to find anything that one would be confident in calling a pure Western here, but I’m sure you’ll find one next winter if not before. Interestingly (well to me anyway), one of the few “good” Western Gulls I’ve seen during the summer months on Vancouver Island was a bird that appeared to be wymani!
