Birds that change colours AND wear snowshoes

I find ptarmigan quite fascinating. They live in alpine and tundra areas. These areas are not typically bird habitat, but ptarmigan like grouse primarily live on the ground. They walk around foraging for plants and occasional insects. They will live in these barren areas all year round, so it isn’t surprising that they are well … Continue reading

The benefits of hoarding

It seems like you can’t walk through Edmonton’s river valley without being yelled at by a red squirrel. It’s pretty obvious that the squirrel is unimpressed by your presence but what exactly is it freaking out about? Chances are, the squirrel is worried you are going to raid its larder and its telling you to … Continue reading

The social networks of trees

Canoeing through Edmonton’s river valley this fall reminded me of the connections between some plants. Trembling aspen trees do produce seeds but their main means of reproduction is through runners. These runners result in colonies of genetically identical trees. The fall emphasizes this as entire patches of trees will all change colour at the same … Continue reading

Why is there green foam on the lake?

I’ve been canoeing a lot this summer, so I’ve also seen a lot of notices about blue-green algal blooms, but this past weekend took it to a whole other level with piles of green foam on the beach and beautifully, but disturbingly coloured banks. While these blooms are relatively common regardless of conditions, warming climates … Continue reading

Save our brains!

I’ve heard about the challenges of indoor air quality a few times. I’ve worked in buildings that had reputations as sick buildings. And oh my word, I’ve been questioning the quality of my home air since moving to working from home. While there are factors that impact our indoor air quality that are independent of … Continue reading

Can geese change when they lay their eggs?

It is later in March and it is currently snowing. Sure, we get late snowstorms, but there’s still several feet of snow, the river is still frozen, and the daily temperatures still sit below freezing regularly. This is definitely a late spring. But the Canada geese are back from their yearly migration, searching for food … Continue reading

To tell a story or not to tell a story

A story is a pretty powerful thing. I’ve had day campers come back to me a year later and repeat some of the stories I’ve told and I’ve watched adults debate the truth of a particular legend told on a canoe trip. The stories we tell ourselves can greatly influence how we respond to trauma … Continue reading

Allergies, climate change, and sinus rinses

I’m an allergy sufferer. I always have been but they seem to have been getting worse in the last number of years. I’m allergic to peanuts but that one is pretty manageable, even with its life threatening-ness. It’s the environmental allergies that are really getting to me. The hay fever for weeks or more in … Continue reading

A Dilemma: Get Outside or Reduce My Footprint?

When I did my PhD research, I worked with outdoor educators on how they connect to climate change in their local environment. One of the things that came out of it was the dilemma of getting outside to be active and connect with natural spaces versus the environmental (and arguably potential social and economic) costs. … Continue reading

The poor snowshoe hare

These two snowshoe hares were on my way into work this morning and it was pretty hard not to stop and take a photo of the difference in their coat colours. Admittedly, neither is especially camouflaged on the manicured greenway they were hanging out on, although the white one could be mistaken for a plastic … Continue reading
