“Crow Scientist” coaches young scientists to head out into the real world and observe crows the way a scientist does. In this free app, real-life crow scientists Colleen & John Marzluff share their knowledge, their photo archives, and their love of crows. Young scientists learn about crow behavior and how to make sense of the crows they observe. The app tracks which observations the young scientist has made—by day, by year, and by lifetime.

Most observations are behaviors, such as “foraging,” and some are calls. The app includes photos of behaviors and audio recordings of crow calls to help the young scientist identify them. Checking all 18 items earns the young scientist a certificate to share or to print out.

Another list describes observations associated with the breeding season, such as juvenile crows or their distinctive begging call. Young scientists love to learn about animal families, and they love to learn to identify crow families. They also learn that in the cycle of life most young crows don’t survive. Again, if the player checks all the items, they earn a certificate to share and print.

Another list identifies rare observations. Can you catch a crow sunbathing? What about a crow with white feathers? it If you can complete this list, you get a certificate that most players will never earn.

The young scientist can even be part of the app. Players can upload images to the app, adding them to the photos that are already there.
“Field Notes” in the app offer some advice for meeting crows “in the wild.”
Players are invited to share their drawings and photos with the Lead Crow Scientist on Instagram.
