This Hawk Figured Out Traffic Signals to Ambush Its Prey

Birds continue to be amazing. Crows can use tools and To keep a grudge against special people. Magpies can know themselves in mirrors. And now, according to the hawks, use traffic signals to hunt predator learn Today was published in the magazine Borders in ethology.

The story is a zoologist and New Jersey at the University of Vladimir Dinets, University of Knoxville, University of Knoxville and a research university in New Jersey. As a zoologist, it has been a long-standing for the prospects of animals and the urban environment and birds, especially in their relations with cars. Scientists observed Ravens Patrol Highway roads, which used cars and songbirds to hide from predators.

When a young Cooper Sahin was relocated to the neighborhood, Dinets had this interesting interaction.

The intersection was not particularly busy, even in a hurry time typed the dinets to the guest editorial for Borders in the ethology. But sometimes, a pedestrian will pass through the street, causing them to collect all the small, shrub, until all of the cars. The signal of the pedestrian can also take a sound that shows the time to walk.

One morning, the dishes saw that the tree was formed, and flew down the car line, passed the street between the cars, and then diving to get something near one of the houses.

Then the same thing happened again. And again.

It turns out that this house liked dinner in the front yard of the family near this house. In response to this, the birds similar to birds and pigeons – they will be dragged there to claim the remaining crumbs.

Designed for easy choices for hawk, dragging the yard and pigeons for the hawk. However, eagerly, Sahin did only when cars flatten along the blocks of the tree.

In the end, Dinets realized that the car line was covered by the road to the hawk and recognize the sound of the “walk” signal. After pressing a pedestrian button, Sahin, hanging and small, flew into the sleeve tree. Then he would wait for cars to hide the protection of cars before using the cover.

Sahin probably learned the pedestrian signal to use the pedestrian signal as a replica to start starting the house.

“This was the vote and as a result of the rest of the car’s turn, he said,” Dinets said. Hawk also had a good mental map of the neighborhood.

Hawk (or thinks that Dinets are the same hawk) returned next year and used the same strategy to hunt. Finally, the family walked away and the signal stopped working, so he did not see any super smart hawk in the nearest house.

Life for birds in cities is difficult – they have to prevent windows, pass cars and do noise. However, this work shows that at least one road adapts to the city.

“I think my observations show that Cooper’s hawks are able to live and develop there, in least partially very smart,” he said.
