Paper on crows by Postdoc David Toews

David mentored the first author, a UBC undergraduate, on this project that used remote field recordings near an urban roost in Vancouver to estimate roost departure time. They found that northwestern crows seemed to maintain a semi-natural circadian rhythm in their roost departures, even with strong variation between days in the timing of anthropogenic noise due to automobile traffic.
