Take a wire and stretch it between two posts and see how many birds land on it. The correct answer is: A Bunch of Birds On a Wire. I don’t know about you, but I never understood this one. Electricity scares me, but for some reason I am enchanted by this plaque.
No worries though. As long as the birds are touching only one power line, they aren’t forming a complete circuit and they aren’t electrocuted.
When birds begin their migration, you might see this behavior called staging. That’s when they huddle close together on a telephone wire or another higher perch. The power lines are a safe, high place where smaller birds can see their surroundings easily and look for possible predators.
Scott Craven (hey that rhymes with raven), a wildlife specialist from the University of Wisconsin, says another possible reason for this behavior might be food. A barn, railroad or highway where grain is handled or shipped are spots where birds like to congregate.
