OMG--those nests are incredible!!
Eagles are quite the architects. And it's fascinating to see where they build their nests, especially up on that high tower--lots of perching areas and unobstructed views! Meanwhile--
I saw a pigeon yesterday, sitting on top of a jersey barrier, (with flashing lights on, in the middle of a busy street intersection, with road crews). Unlike eagles, city birds don't exert themselves into making homes--they're happy to just freeload on whatever construction project, the humans put out there!
