It has been a chuckle watching all of the airports efforts to keep these birds from roosting, including raptor recordings and maintenance staff clapping wood together loudly. To be honest, it is amazing to see how many of them perch on the overhangs, which in themselves are a neat looking feature.
Too bad we cant get some of the regional peregrin falcons from nesting nearby - they have done a great job of reducing the pigeon population culled downtown and in my neighborhood in Lakewood (including a couple surprises in my backyard!).
