In the United States, raven populations are reportedly building their nests on electrical poles, which has made them a larger threat to some endangered species.

Experts say that in western states, raven populations have gone up by an estimated 300 percent in the last 40 years.

Ravens prey on sage grouse eggs, along with endangered species like the desert tortoise, and a species of bird known as the San Clemente loggerhead shrike.

According to data from a study by researchers at Idaho State University, 58 percent of the ravens involved in the study made their nests on top of electrical poles.

The study focused on an area that is mostly sage brush, and found that generations of ravens are making their nests on the electrical poles.

Kristy Howe, co-author of the study from Idaho State University said: “Power lines are dangerous and electrocute many species of birds, the ravens are running that same risk as well. The benefits to them outweigh the risks.”

From the high vantage point, the ravens can see further which also makes for an easier take off and allows them to have a higher speed of attack.
