Emily S. Rueb in The New York Times:
Mr. Harinarain, a heating and air-conditioner repairman from Brooklyn, joined a procession of middle-aged men in fedoras and flat caps, cradling wood poles and cages the size of large shoe boxes, streaming into a pocket-size park in Richmond Hill, Queens, on a recent Sunday morning. The cages were blanketed in white coverlets, some trimmed with lace. Inside each one was a delicate songbird: a chestnut-bellied seed finch native to the northern parts of South America and the Caribbean.
Sundays are race days, though the events are not really races but speed-singing contests. Two cages each containing a male finch, whose fierce calls are triggered by an instinctive desire to woo females and defend turf, are hung on a pole about an inch apart.
