Because the mating calls of city birds often compete with traffic’s din, many have to raise their pitch in order to be heard. This is not only true for city birds, but also for urban
“crickets, frogs and other animals.”
The trouble is, “females often judge a male’s virility and worthiness as a mate by the deepness of his voice.” Higher-pitched voices might therefore deter otherwise-eager mates. The species as a whole may eventually diminish in strength and numbers.
Which just goes to show: “City life isn’t for everyone.”
