In the total absence of the tent caterpillar or apple-tree worm, which is their favorite food, cuckoos seem to succeed in finding a large green worm here in the orchard. In the beech woods they can find a forest worm that is riddling the leaves of the beeches. The robins are there in force and I hope the cuckoos will join them in the destruction of the worms. It is interesting to see the cuckoo fly by several times a day with a big green worm in its beak. Inefficient as it seems, here it is doing things. It is like seeing a monk at the plough-handle. It is a solemn creature; its note is almost funereal.
Our indigo bunting is as artful and secretive about its nesting-habits as any of the sparrows. The male bird seems to know that his brilliant color makes him a shining mark, and he keeps far away from the nest, singing at all hours of the day in a circle around it, the radius of which must be more than fifty yards. In one instance the nest was near the house, almost under the clothes-line, in a low blackberry-bush, partly masked by tall-growing daisies and timothy. I chanced to pass near it, when off went the little brown bird with her sharp, chiding manners. She is a very emphatic creature. It is yea and nay with her every time.
The male seems like a bit of the tropics. He is not a very pleasing singer, but an all-day one and an all-summer one. He is one of our rarer birds. In a neighborhood where you see scores of sparrows and goldfinches you will see only one pair of indigobirds. Their range of food is probably very limited. I have never chanced to see them taking food of any kind.
How crowded with life every square rod of the fields and woods is, if we look closely enough! Beneath my leafy canopy on the edge of the beech woods where I now and then seek refuge from a hot wave, reclining on a cushion of dry leaves or sitting with my back against a cool, smooth exposure of the outcropping place rock, I am in a mood to give myself up to a day of little things. And the little things soon come trooping or looping along.
I see a green measuring-worm taking the dimensions of the rim of my straw hat which lies on the dry leaves beside me. It humps around it in an aimless sort of way, stopping now and then and rearing up on its hind legs and feeling the vacant space around it as a blind man might hunt for a lost trail. I know what it wants: it is on its travels looking for a place in which to go through that wonderful transformation of creeping worm into a winged creature. In its higher stage of being it is a little silvery moth, barely an inch across, and, like other moths, has a brief season of life and love, the female depositing its eggs in some suitable place and then dying or falling a victim to the wood pewee or some other bird. After some minutes of groping and humping about on my hat and on dry twigs and leaves, it is lost to my sight.
