I notice that in Dallas, TX a great deal of birds sit at very specific intersections such as Plano Rd and Beltline in Richardson. Not being a native of Texas, I can't recall seeing this type of activity (perhaps the birds are just larger here like everything else!). They sit on the wires, atop trees but only on certain corners. And of course they sing like crazy. Anybody know why?
Birds like to be in high places. They have a better view up there and are safer from grounded predators. As for being in certian places, I think it has to do with territory. ) I just love to hear their song.
Birds don't only sit on wires, but on almost everything . But on the electricity wire, we see them very clearly and that seems very unusual to us, but it isn't. For them it's just another (handy!) place to sit on.
Many animals, birds among them, are sensitive to magnetic fields, and it's possible the lines you're talking about have just the right amount or kind of field they like. It's also possible there was a grove at that intersection in the past, and their racial memory is respondng to that. Or it could be that there is a large amount fo food in the area, and not enough tree branches nearby.
Birds have adapted to many of the contraptions created by man, they are simply taking advantage of man-made structures as a perch on which to rest and watch for predators. Groups of birds are often seen perching together , especially during the winter when species leave breeding territories and congregate for safety or to migrate.
They are social creatures and likely to hang out where everyone else does - like people! They tend to gather in flocks too. If it's near intersections my guess would be that's because it's between two clear fly zones, where there are not tall trees or buildings to get in their way as they fly. They like to stay relatively close to the ground for warmth, water, food, actionand wires are everywhere so they are used to hanging out there. Another thoughtPeople are not going to bother them or threaten them if they are sitting on electrical or telephone wires - those birds who sat there learned that, and the birds who chose the buildings and windowsills didn't fare as well. The survivors spread the wisdom to their offspring (a Darwinian explanation, but makes sense even if you're not a Darwinian).
