Small Peculiar

I love the dance with which male pigeons try to get their hens in the mood. How many things can be described as bold and dainty? But Columba livia‘s courtship display is both. Per Wikipedia, “Alighted males inflate their crops, puffing up the feathers on his neck to appear larger and thereby impress or attract attention. … [The male] approaches the female at a rapid walking pace while emitting repetitive quiet notes, often bowing and turning as he comes closer. At first, the female invariably walks or flies a short distance away and the male follows her until she stops. At this point, he continues the bowing motion and very often makes full- or half-pirouettes in front of the female.” How do they all know to do this same dance? Do they teach each other? Or is it instinctive?
