On the hard, frozen surface of winter wetlands it looks like all is calm, all is bright.
But if you could plunge beneath that icy crust as if a pond or marsh were an aquatic Creme Brule, you’d see a slow, but still-living world where mammals fish, insects and amphibians might not thrive, but they survive. They’re hunkered down to wait out that season that makes our brave Canadian hearts swell with pride.
Jacques Bourgeois is the communications and marketing coordinator of Oak Hammock Marsh Interpretive Centre in Manitoba. He explains how dragonflies turn into snowbirds, frogs freeze and thaw like Butterballs and fish chemistry to their advantage. Oh, and turtles? They breathe from an unexpected orifice.
In Charles Dickens' A Christmas Carol Mrs. Cratchit makes a small goose into a family feast. And she renders it delicious and delicate. But, how, many Canadians -- who think of goose as a greasy nightmare before Christmas -- "How did she pull off that Christmas miracle?" To find out I spoke with Pat Kehoe with DUC and a game roaster of renown. If the Great British Bake-off had Goose Week, Pat would win hands down. He shares secrets for goose goodness.
In this episode we explore the intertwingled intersection of conservation and hunting. Can you both care about wildlife and its habitat and take an animal’s life?
Next, rain, snow and sleet show up on meterologists’ radar screen. But sometimes weather boffins spot something else on their glowing monitors. Something else that has nothing to do with clouds, forecasts or humidex reports.
We start with the fine art of bird banding. Researchers find a bird they want to track and, as Beyoncé might say, “put a ring on it.” We’ll discover the history, purpose and process of avian bling.
Then, we travel to Cape May, New Jersey where we chat with a birding expert and author who wants to help us identify birds in their habitats. Richard Crossley has created a series of books, including one on ducks, to help us do just that.
Eider feathers, or down, aren't just for duvets. In fact, a hormone in those feathers called corticosterone, can indicate the stress eider ducks have been under as they molt. Yukon-based eider researcher Jane Harms explains that stress can be due to nearby predators or sometimes changes in their environment. So, not only can the stress hormone indicate eiders' health and their ability to reproduce, it may also be an indicator of climate change. Get undercover and tune into the tale.
Wetlands are delicate ecosystems. So the last thing researchers really want to do is churn up those wetland waters just to sample them. But what if a flying robot could do that for them? How? We do a flyby visit with a young inventor, Nathan Hoyt, who worked with a small team of high school students to figure it out. Plus, they're making a business out of it. Listen in. We promise we won't drone on.
