Uneasy neighbours: red foxes and arctic foxes in the north

It’s tough out there in the arctic. It’s a real fox-eat-fox world. Literally! Take a virtual trip up to the Yukon’s arctic coast and learn about the complex and, at times, tenuous co-existence of two northern icons: the red and arctic fox.

The Dangerous and the Benign: distinguishing between big scary bugs

Some participants of the 2020 Bioblitz got a bit of a scare when they discovered a large insect with what appeared to be a massive stinger. Since Asian giant hornets aka “murder hornets” had recently made headlines with their unwelcome appearance on the west coast of North America, it was reasonable to worry that they may have traveled north to our territory. But we are here to squash that fear! The big scary bug you may be spotting in your backyard is neither murderous nor a hornet. It also doesn’t actually have a stinger! Learn about the harmless wood-loving horntail and how it couldn’t be more different than the dangerous hornet it was mistaken for.

Bear Poo and You: learning about Yukon Bears with the OURS research project

People say there’s more than one way to skin a cat but there’s also more than one way to survey a bear. One of those ways is through their scat! Operation Ursus Research using Scat is doing exactly this and you can be a part of it. Learn how these surveys are conducted, why they’re important, and how you can help improve our knowledge of Yukon bears by collecting their poo.

Rusty Blackbird: the mysterious decline of a common boreal bird

The aptly named Rusty Blackbird is regular fixture in the boreal forest and can often be spotted in wetlands and hanging out by slow moving streams. Until recently, very little was known about this opportunistic water-loving bird but as we learn more about them, we’ve also learned that their populations are in decline. What’s causing this drop in Rusty Blackbird numbers? We’re not entirely sure. Read on to learn how scientists are using modern
technology and recent discoveries to help unravel this mystery. Written by Pam Sinclair in conjunction with Joelle Ingram

Love for the Lynx

While the ungulates have already gone through their languages of love the carnivores are just getting started!
It’s a great time to hear the courtship calls from the lynx, arctic fox and red foxes.
