Thanks to Lorenzo for suggesting the northern gannet this week! We'll also learn about an extinct ancestor of the gannet, called plotopterids! Don't forget to enter our book giveaway! Details here. The northern gannet is the assassin of the bird world, probably: DIVING! It's what they do: Northern gannets hanging out on their nesting grounds: An artist's rendition of a plotopterid, with the silhouette of a modern emperor penguin for comparison. Picture from March of the Fossil Penguins. Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. This week let’s learn about two interesting birds! Thanks to Lorenzo for the suggestion! But first, an announcement! I’m doing a giveaway of my books Skytown and Skyway! The giveaway runs through October 31, 2020 and is open to anyone in the world. To enter, just let me know you’d like to enter. You can email me at strangeanimalspodcast@gmail.com, leave me a message on Twitter or Facebook, or anything else. All I ask is that you make it clear that you want to enter and let me know how to contact you if you win. On Halloween night at midnight I’ll choose one name at random from everyone who enters and that person will win one paperback copy of each book, and I’ll also throw in some stickers, bookmarks, a pencil that says “I bite mean people,” and probably some other stuff. I’ll also sign the books if you like. If you want to take a look at the books to see if they sound interesting, I made a new page on the strangenanimalspodcast.blubrry.net website with links. Please enter. It will be embarrassing if no one does. Anyway, Lorenzo wants to hear about the northern gannet, a sea bird that sort of looks like a gull who mastered the blade and is probably an assassin. Its bill is large, silvery-blue, and dagger-like, outlined with black at the base that makes a dramatic mask. This mask is actually bare of feathers, showing the bird’s black skin. Otherwise it’s mostly white, with a wash of pale golden on the head and neck, black-tipped wings, and gray legs with webbed toes. But it’s also really big, almost the size of a pelican. Its wingspan can be over six feet, or 184 cm. It can weigh almost 8 lbs, or 3.6 kg, too. Like many sea birds, the northern gannet breeds in colonies that can number in the thousands, and it only breeds on oceanside cliffs, mostly on islands off the coast of eastern Canada, Iceland, and western Europe. It’s especially common around the British Isles. So many birds may be nesting at once that the cliffs appear white from a distance, like snow fell on the clifftops, but instead of snowflakes, it’s gannets! While the northern gannet will sit on the water after diving, the only time it actually sets foot on land is when it breeds. It doesn’t walk very well, which is why it nests on cliffs. It’s easier for it to get airborne from a cliff. It can only take off from the water by facing into the wind and flapping hard, but if it’s not windy enough it can’t get airborne and it just has to float there until the wind picks up, probably feeling pretty foolish. But it swims well so if it is stuck on the water, it can swim along with its head under water, looking for fish it can grab. But most of the time the northern gannet is in the air, and it is built for speed and efficiency. Its long, narrow wings allow it to reach high speeds, up to 40 mph, or 65 km/h. It’s not very maneuverable, though, except for one specific move. The northern gannet is a diver. It’s a diver extraordinaire! It can reach incredible speeds while diving, up to 62 mph, or 100 km/h. When it dives, it holds its body rigid and angles its wings back, then folds the wings tight against its body just before it hits the water. It can dive up to 36 feet deep, or 11 m, and then it will swim farther down, sometimes over 80 feet deep, or 25 m. Its eyes are sharp and adapted to seeing both underwater and above water,
