Birds sense speed limits on roads: Study
OTTAWA, Province of Ontario (AFP) - Birds sense posted speed limits on roads and react to avoid collisions, according to a study out on Wednesday.
Researchers said birds appear to have adapted to the local speed limits as a feature of their environment, such as the risk of predators.
Strict enforcement of speed limits could therefore significantly help with conservation, especially for endangered species in populated areas, Mr Pierre Legagneux, a behavioural ecologist at the University of Quebec in Rimouski, told AFP.
"I realised that the birds were not reacting to the actual speed of my car, but to the average speed of cars on these roads, to the posted speed limits," the lead researcher said in a telephone interview.
