(Again) another factoid I remember hearing is that birds have different "accents" in the cities and country. They sing in a slightly higher pitch in the city because it bounces off buildings better, but the deeper pitch travels better in open spaces and the woods.



I have never came across that before , did it take into consideration volume ?
Eugene Morton came up with the "ranging hypothesis "in the 70's which suggested that distance and degradation of song was important in responses to songs in the same species i.e.clear loud songs evoke more violent repsonses than fuzzier degraded and hence more distant ones .
