Grebe ID Mix-up on Life

On Sunday Discovery Channel “premiered” the documentary Life; or rather the American edition of it which is narrated by Oprah Winfrey. I had already watched the version narrated by David Attenborough, which Discover Channel Canada aired in November of last year, but I enjoyed the series so much that I wanted a second look at it. Much to my surprise I noticed that they had incorrectly identified two Clark’s Grebes as Western Grebes in the series first episode.

Here is a clip from the version narrated by David Attenborough showing the courtship display of two Clark’s Grebes. Note that they are correctly identified as Clark’s Grebe.

I was unable to find a video from the American version showing this scene but it is pretty much the same footage, just edited differently. Does anyone happen to have a link to this version’s scene of the Grebes?

I did, however, notice that on Discovery Channel Canada’s website for the show they also incorrectly mention Western Grebes as being featured in the documentary.

It’s a bit disappointing to see this in a show with footage of such high quality, and seeing as how the original script had the correct ID I don’t know how this could have been messed up. It kinda throws into doubt all of the information in the narration; if they messed one thing up could there be anymore errors?

Always be Prepared! A walk down The Pier at Lonsdale Quay

Last week Tuesday I was out running some errands in the Lower Lonsdale neighbourhood and I decided to have a stroll down the Burrard Dry Dock Pier. I wasn’t “prepared” per say for birding but I always carry a small pair of Bushnell Powerview 10×25’s in my jacket pocket; arguably horrible binoculars but better than nothing.

It was a good thing I had those binoculars because there was about 49 Barrow’s Goldeneye and 13 Western Grebe among other birds in the vicinity of the pier.

The Barrow’s Goldeneye were diving in and amongst some wood pylons close to shore. Initially some of them appeared a bit nervous of my presence on the pier, which was only a few meters away from where they were diving but they soon returned to feeding. Insects, molluscs, and crustaceans form a major part of this species diet and food is most often taken in shallow water along the shoreline (1,2). The water was clear enough for me to watch some of them foraging underwater; with their tails spread out and wings clamped close to their bodies they make for agile swimmers (3).

As I walked towards the end of the pier I spotted thirteen Western Grebe; most of which were preening and resting while one or two cruised along the water’s surface.

Always having a pair of binoculars on hand, even when the purpose of one’s outing isn’t birding, has paid off for me on several occasions and I’m sure many of you who are reading this keep a spare pair in some convenient location. After all there are birds everywhere and one always has to be ready for action!
