After an underground car park was converted into a bike centre at a British Columbia campus, there was worry that nesting swallows who used the space as their home wouldn’t be able to get in and out. After all, a pair of automatic doors were installed. And birds didn’t know how to use those doors, right? Wrong!
Watch this video and see just how smart these swallows are. Not only do they figure out how to make the doors open for them to fly outside, but they also hover around the doors on the other side to trigger the outdoor motion detectors.
We always knew corvids were pretty smart, but now we can add swallows to that intelligence list.
