The Hummingbird Festival in Sedona

I just got back from the Hummingbird Festival in Sedona, Arizona. It was an honour to be invited there to present our work on flight.

The audience at the festival had a ton of great questions and I learned a lot. For example, the Anna’s hummingbirds are a fairly recent arrival in Sedona, just as they are in Vancouver, because urbanization has also allowed the species to gradually expand its range east into the desert (as well as north). I wonder how that has affected the hummingbird community there? I also learned that it is pretty easy to set up an outdoor Drosophila colony as a protein source for breeding hummingbirds.

We saw the Grand Canyon and more bats, hummingbirds, and aura photographers than ever before in one place. Arizona has great insects, too. My favourite? The “pleasing fungus beetle” we spotted at Starbucks.

Flight school

Our research on hummingbird flight is featured in the July 2017 National Geographic!

The article is all about hummingbird science, and how new techniques are allowing us to see aspects of their behaviour that aren’t available to the unaided eye. You can read the print article here, see a beautiful video summary here, and another one here. Here’s one of an Anna’s hummingbird in a wind tunnel. He’s remarkably good at keeping his head steady as the wind ramps up:

The photographer, Anand Varma, took a great shot of my vision experiments at UBC that shows a bird perching in a strange, Tron-like environment of glowing green stripes:

Between getting the scene right, adjusting the lighting, and then waiting for the bird to act in just the right way, this one photograph took an entire week of work (hands on work that is, no photoshop!). Given all the other complex shorts in the article, it’s easy to see how the whole endeavour took a couple of years – much like a scientific study. Working with Anand that week, it was interesting to see how many other parallels there are between what he does and our research. A lot of trial and error, a lot of patience, and a lot of coping with the quirks and surprises of animal behaviour.

The article ends with a scene from the summer when the writer, Brendan Borrell, spent a couple of days with me in the lab. I have the honour of being described as emerging from the lab with a “sheen of sweat” on my forehead. It is embarrassing, but true! It was a hot day and we were working hard in that room.

There is also a nice editorial about the project here.
