CURWOOD: Starting April 26th, thousands of people in hundreds of cities around the world will be participating in the City Nature Challenge, organized by the California Academy of Sciences. The event is what’s known as a bioblitz - a brief, intensive survey of biodiversity over a set area and time. Participants use their mobile devices to photograph the nature in their neighborhoods. The photos are then uploaded to an app called iNaturalist, where experts help identify every observation made. The data collected is available to any scientist for research. To practice their observational skills before the challenge, the Boston BioBlitz Initiative for Girls took some girls aged 12 to 15 to Thompson Island in Boston Harbor where they found some surprising evidence of local animals.

VOICE #1: Poop. Coyote poop.

VOICE #2: Scat. Look at that scat, guys.

VOICE #1: Do you all see that?

VOICE #3: Someone should photograph that!

VOICE #2: Who’s going to iNat that?

VOICE #4: Do you want me to take a picture?

VOICE #5: Yeah, take a picture.

VOICE #2: Alright, so remember with iNaturalist, we not only can document things that are
alive, we can document things that are dead, and we can document evidence of species. And so, taking a picture of this scat is a great thing to add.

VOICE #3: And I know this is poop, but it’s mostly hair of animals, so I’m going to touch it with the sticks. I’m just trying to show that there’s bones in here, which’ll make it clear that it’s probably not a dog.

VOICE #6: Coyote?

VOICE #4: Bone in the poopy?

VOICE #3: Bone in the poopy! And look at the photo she was able to take using the
magnifying lens.

VOICE #5: Bone in the poopy?

VOICE #4: Bone in the poopy.

VOICE #5: Whoa, there’s a bone in the poopy.

VOICE #7: So you have coyotes on the island?

VOICE #1: We do.

VOICE #7: That’s so interesting!

VOICE #1: They appeared here just a few years ago, just a male and female adult that came over, so we have a land bridge that opens up at low tide. So they made their way over, and then they had pups, so they had pups here. And so now we have a family, a grown-up family, that lives somewhere around here. They stay pretty much to themselves.

CUROOD: The City Nature Challenge will take place around the world from April 26 to 29 and it’s not too late to get involved. Anyone with a smartphone has the needed equipment, and you can find out how to participate on the Living on Earth website, loe.org.
