in Thoreau’s Journal:

To Walden

The seringo, too, has long been silent like other birds. The red prinos berries ripe in sunny places. Rose hips begin to be handsome. Small flocks of pigeons are seen these days. Distinguished from doves by their sharper wings and bodies. August has been a month of berries and melons, small fruits. First in the descent from summer’s culminating-point. There is a stillness in nature for want of singing birds, commenced a month or more ago; only the crickets’ louder creak to supply their place. I have not heard a bullfrog this long time. The small cornel, or bunch-berry, is in bloom now (!!) near the pond. What great tuft-like masses the cow-wheat makes now in sprout-lands!
