Odd Gyrations of Hummingbirds
Odd Gyrations of Hummingbirds.
I would like to ask if anyone has observed a sort of dance or gymnastic exercise of the hummingbird similar to that which I once witnessed? It was just after sunset of a clear, bright day in San Mateo, Cal., when I noticed a male Anna hummingbird making great circles in the air at a very rapid rate. The plane of the circle was perpendicular and I should judge it was fifteen feet in diameter. He rose somewhat more slowly than he swung down again, hut the whole movement reminded me of a stone whirled at the end of a very long string. Was this to impress the female or merely for the joy of motion?
