Thoreau's Journal: 2-Feb-1854
This from Greg's The Blog of Henry David Thoreau
The scream of the jay is a true winter sound. It is wholly without sentiment, and in harmony with winter. I stole up within five or six feet of a pitch pine behind which a downy woodpecker was pecking. From time to time he hopped round to the side and observed me without fear. They are confident birds, not easily scared, but incline to keep the other side of the bough to you, perhaps.
Already we begin to anticipate spring, and this is an important difference between this time and a month ago. We begin to say that the day is springlike.
Is not January the hardest month to get through? When you have weathered that, you get into the gulfstream of winter, nearer the shores of Spring.
