watch live Peregrines are cliff nesters, and the water tower on the UND campus makes a suitable substitute. Passing birds were lured to stop by placing a nest box, first on Smiley, the water tower that stood just southeast of the Washington Street underpass. When that tower was replaced, the birds were lured to the UND site. The local falcon effort is part of a larger undertaking going on around the world. As a result, peregrine falcons may be as abundant as they have ever been, and they are surely more widespread. The birds were endangered, and even doomed, within my lifetime. I made a number of trips in search of peregrines, and found them at Assateague Island, Va., and along the Gulf Coast near Galveston, Texas. As I mentioned earlier this year, I had an encounter with a peregrine while having lunch at the top of the Prudential Tower in downtown Boston.
