The sound of one swan galumphing across the water, feet windmilling and wings flapping so hard that they whipcrack, in pursuit of another swan even more frantically doing the same in an attempt to escape. This sunny morning in Centennial Park seems to have put quite a few of them into a feisty mood. I seem to be hearing this noise every five minutes or so.
If you,ve never heard it, imagine hoofbeats splashing through a river ford, with an overlay of wind rushing through feathers. Pegasus cantering through a thunderstorm, perhaps?
