Crows attacking students became such a big occupation at Langara College inwards Vancouver that GIS instructors Jim O’Leary in addition to Rick Davidson decided to arrive at an interactive map that enables people to study locations where crows arrive at got attacked.
The CrowTrax map allows anyone to add together a place where they arrive at got been attacked past times a crow. So far the map has had thousands of locations added to the map. And non only inwards Vancouver. Crowtrax has been inwards functioning for 3 years now. You tin thought the locations added to the map inwards previous years past times selecting a yr from the map menu.
This isn't the showtime fourth dimension that has had to study on aggressive birds.

The map too allows y'all to thought the locations where geese arrive at got been known to nest inwards previous years.
The middle of the Goose Watch interactive map is the Brooding Goose Problem routing engine which helps students avoid the brooding (and sometimes aggressive) geese.
