A phoebe soon built in my shed, and a robin for protection in a pine which grew against the house. In June the partridge, which is so shy a bird, led her brood past my windows, from the woods in the rear to the front of my house, clucking and calling to them like a hen, and in all her behavior proving herself the hen of the woods.—Walden
[A]nd even the sepals from which the birds have picked the berries are a brilliant lake-red, with crimson flame-like reflections, equal to anything of the kind,—all on fire with ripeness—"Autumnal Tints"
As Anacreon says "the works of men shine," so the sounds of men and birds are musical.—Journal, 8 March 1853
As we stood on the pile of chips by the door, fish hawks were sailing overhead; and here, over Shad Pond, might daily be witnessed the tyranny of the bald eagle over that bird.—The Maine Woods
Books of natural history make the most cheerful winter reading. I read in Audubon with a thrill of delight, when the snow covers the ground, of the magnolia, and the Florida keys, and their warm sea breezes; of the fence-rail, and the cotton-tree, and the migrations of the rice-bird; of the breaking up of winter in Labrador, and the melting of the snow on the forks of the Missouri; and owe an accession of health to these reminiscences of luxuriant nature.—"Natural History of Massachusetts"
Dense flocks of blackbirds were winging their way along the river's course, as if on a short evening pilgrimage to some shrine of theirs, or to celebrate so fair a sunset.—A Week on the Concord and Merrimack Rivers
Even as the birds sing tumultuously and glance by with fresh and brilliant plumage, so now is Nature's grandest voice heard, and her sharpest flashes seen.—Journal, 19 May 1856
How often are we wise as serpents without being harmless as doves!—Journal, 9 February 1851
I also heard the sound of bullfrogs from a swamp on the opposite side, thinking at first that they were a moose; a duck paddled swiftly by; and sitting in that dusky wilderness, under that dark mountain, by the bright river which was full of reflected light, still I heard the wood thrush sing, as if no higher civilization could be attained.—The Maine Woods
I am no more lonely than the loon in the pond that laughs so loud, or than Walden Pond itself. What company has that lonely lake, I pray? And yet it has not the blue devils, but the blue angels in it, in the azure tint of its waters. The sun is alone, except in thick weather, when there sometimes appear to be two, but one is a mock sun. God is alone,—but the devil, he is far from being alone; he sees a great deal of company; he is legion. I am no more lonely than a single mullein or dandelion in a pasture, or a bean leaf, or a sorrel, or a horse-fly, or a humble-bee. I am no more lonely than the Mill Brook, or a weathercock, or the northstar, or the south wind, or an April shower, or a January thaw, or the first spider in a new house.—Walden
