Lizard Lassoer

Earyn McGee is a scientist who treks through the desert to study lizards

Earyn McGee shows off a lizard that she caught with her lasso.

From 2016 to 2021, Earyn McGee spent hours hiking through Arizona’s Chiricahua Mountains. She was searching for lizards as part of her Ph.D. project at the University of Arizona. Armed with an extendable pole with a loop of thread at the end, McGee would sneak up on any tiny lizard she came across. Then she’d slip the snare over its head and gently catch it. “It’s kind of like fishing and lassoing lizards at the same time,” says McGee. “It’s very fun, and it’s not as hard as it seems.”

Once she catches one, she notes its species, determines if it’s male or female, measures it, and collects other data. She compares this data with information about the lizard’s habitat. This helps her better understand the lizard population, how healthy it is, and the threats it faces, like droughts or wildfires.

McGee is a herpetologist, a scientist who studies amphibians and reptiles. As a kid, she spent a lot of time outdoors looking for animals. But it wasn’t until college that she learned she could make a career out of it. She enrolled in a research program and chose to study lizards. “I fell in love with them. I got the chance to try to answer questions I’d had since I was a kid, like: What do lizards eat? Where do they sleep? How do they communicate?” McGee says.

From 2016 to 2021, Earyn McGee spent hours looking for lizards. It was part of her research at the University of Arizona. McGee hiked through the Chiricahua Mountains of Arizona. She carried a long pole with a loop of thread at the end. When McGee came across a lizard, she carefully snuck up on it. Then she slipped the loop over its head. She tightened the loop to gently catch the animal. “It’s kind of like fishing and lassoing lizards at the same time,” says McGee. “It’s very fun, and it’s not as hard as it seems.”

Once McGee catches a lizard, she collects some data. First, she writes down what species it is. She also measures it and checks if it’s male or female. Later, she compares her data with information about the lizard’s habitat. This helps her understand the size of lizard populations. It can also tell her whether threats like droughts or wildfires are affecting them.

But she didn’t realize she could make it her job until she was in college. McGee signed up for a research program.

Yarrow’s spiny lizard

To share her love of lizards with the rest of the world, McGee started a game on social media called #FindThatLizard. Every Saturday, she posts a photo of a lizard in its habitat. The camouflaged lizard blends in with its surroundings, and players try to find it. But it can be hard! She also includes fun lizard facts on each post. Her first #FindThatLizard post shared that the Yarrow’s spiny lizard (right) doesn’t lay eggs. It gives birth to live babies!

McGee wants to share her love of lizards with the world. So she started a game on social media called #FindThatLizard. Every Saturday, she posts a photo of a lizard in its habitat. Players try to find the lizard. But lizards are great at camouflage, or blending in with their surroundings. So they can be hard to find! McGee also includes fun lizard facts. For example, the Yarrow’s spiny lizard (right) doesn’t lay eggs like most lizards. It gives birth to live babies instead!

McGee feels strongly that education is a crucial part of conservation. And the game is a fun way to teach people about lizards. “I hope when people learn how cool lizards are, they’ll start to care about them more,” she says.

A. For her Ph.D. research project, McGee counted the number of lizards in two different habitats. On one visit to the habitat with a year-round water source, she caught 15 lizards. On a trip to the habitat with a seasonal water source, she caught 5 lizards. Find the ratio of lizards McGee caught by the year-round water source to the number she caught by the seasonal water source.
