I don't think we could be in a city without thinking about pigeons.

And for many people, it's one of the few daily interactions that they have with wildlife.

Elizabeth Carlin, a graduate student at Fordham University in the Bronx.

As an evolutionary biologist, Carlin was curious about whether pigeons in one city are closely related, genetically speaking, to those from cities nearby.

So she did a research-inspired road trip, making stops from Boston to D.C.

I would drive to a city and then start talking to people at Starbucks.

Anybody that I could chat with, I would start asking them questions about

where they saw pigeons and kind of start to gather until that way. Once she'd found a flock,
