Amelia: This urban pond was a great discovery. Look, the community has even installed nesting boxes on tall poles around the pond. I wonder who’s nesting in them. Oh, a bird’s head popped out of that box- I’ll go check it out.

Tree Swallow: Hello, this nest is taken. You can’t use it. Goodbye.

A: Wait- I’m not interested in taking your nest. I just wanted to meet you. What kind of bird are you?

Ghosts flying around

Patty Rooks

Well, it would not be Halloween in southeastern Alberta if it was not going to be cold and perhaps snowy! As I write this article, the weather is supposed to take a change for the worse on the weekend, but that is OK. If anyone can do it, we can, as we know how to celebrate this holiday even if we have to wear a winter coat over your costume.

I am VERY excited to see all of the ghosts and goblins at my house in just a few days. In order to keep you busy until then, here is a frightful experiment that MUST be done with an adult. Let’s get started!

Lampreys: Terrifying Alien Monsters or Fascinating Ancient Fishes?

Noel Alfonso's avatarCanadian Museum of Nature Blog

Lampreys get a bad rap.Their tooth-filled oral disksdefinitely look scary. Elongate squirmy exoparasites aretrulyfrightening. But here’s the thing:theseancientfishesare ancient survivors thatareakey component of freshwater ecosystems.

Experts disagree, but there areanywherebetween42and48 species,all butfivefoundin northern temperate areas. They occur from Alaska to Newfoundland in North America,and Portugal toSiberia inAsia.Although theymaylook like eels, they are very different from modern bony fishes.These cartilaginous fisheslack jaws, scales,and pectoral and pelvic fins.Most are small, around 15 cm,butone species—the Sea Lamprey—reaches120cmin marine environments. Different species can be identified by tooth pattern.
