Migrants are arriving regularly now as the season progresses. On a large pond there was a flock of Canada geese that numbered well over one hundred; but more interesting were the tundra swans, seven in number.
As a red-tailed hawk circled overhead –
All of the geese took to the air –
Leaving the pond to the swans –
And one lone male ring-necked duck
Back when I was a young naturalist (instead of an old naturalist) tundra swans were known as whistling swans and before that they were called American swans - and then there's the scientific name (Cygnus columbianus). Like many other birds their name has been changed over the years – they must be confused by the fickleness of the humans who name them.
