How many species of penguin are there?
When I first became obsessed with penguins about 20 years ago, after an expedition to Antarctica and then volunteering for a penguin census in Argentina, there were 17 species of penguin, according to this Penguin Bible. And, because you must know this, here they are, divided by group:
Large penguins: King penguin, emperor penguin
Brush-tailed penguins: Adélie penguin, chinstrap penguin, gentoo penguin
Yellow-Eyed penguins: yellow-eyed penguin
Crested penguins: southern rockhopper penguin, northern rockhopper penguin, penguin erect-crested penguin, Fiordland penguin (Tawaki), Snares penguin, macaroni/royal penguin
Banded penguins: African penguin, Magellanic penguin, Humboldt penguin, Galápagos penguin
Little (or Blue) penguins: Little penguin

Around the time I was getting to know penguins, the rockhoppers began to be recognized as two different species — and while Penguins lists the macaroni and the royal penguins as one species, some ornithologists consider them to be two species, which brings the number to 18.

In addition, some research advocates splitting the southern rockhopper penguin into two species (eastern and western). Other evidence indicates the little penguin should be considered two species as well.
And, most recently, research suggests that the gentoo species be split into four species. (This article also has background about penguins’ 22-million-year history. Check it out.)

It’s all quite fascinating … and even with my penguin obsession I’m having a hard time keeping track. I hope one day to meet all the species of the penguin world … and this new information definitely makes my plans a bit more interesting.
But for now, the official number is 18. And counting.
And if you want to meet some penguins without getting on a plane, here’s where you can find them in my novels!
For Adélie, chinstrap, gentoo, and Magellanic penguins — and a lone emperor:

For Galápagos penguins:

And stay tuned! While I didn’t plan to be a penguin novelist, I just can’t seem to escape them. Since writing My Last Continent and Floreana, I’ve been fortunate to meet little/blue penguins, Tawaki, yellow-eyed penguins, and most recently, the shy and elusive Humboldts.
