If occurrance is a criteria, then we'd have to go with 1) Starling, 2) Crow,
3) House Sparrow, 4) Robin, 5) Rock Dove, 6) Glaucous-winged Gull, or
impact,(watch where you step) 7) Canada Goose. Maybe I'm spending to much
time around the refuse containers at the zoo. Actually my vote goes to the
Peregrine as well.
