There is doubtless just as much "charming" in this case as in any other, or when a fish hawk falls through the air and seizes a fish near the surface in perfectly clear water—what hinders the fish from seeing and avoiding its enemy? Apparently nothing; apparently it allows itself to be seized. Every fisherman knows how alert most fish are, how quickly they discover him and dart away, even when he is immediately above them. All I contend for is that the snake, the cat, the hawk, does not exert some mysterious power over its prey, but that its prey in many cases loses its power to escape through fear. It is said that a stuffed snake's skin will charm a bird as well as the live snake. I came near reaching a hasty conclusion the other day with regard to a chickadee's nest. The nest is in a small cavity in the limb of a pear-tree near my study, and the birds and I are on very friendly terms. As the nest of a pair of chickadees had been broken up here a few seasons ago by a mouse or squirrel, I was apprehensive lest this nest share the same fate. Hence when, one morning, the birds were missing, and I found on inspection what appeared to be the hair of some small animal adhering to the edges of the hole that leads to the nest, I concluded that the birds had been cleaned out again. Later in the day I examined the supposed hair with my pocket glass, and found it was not hair, but some vegetable fibre. My next conclusion was that the birds had not been molested, but that they were furnishing their apartment, and some of the material had stuck to the door jambs. This proved to be the correct inference. The chickadee makes a little felt-like mat or carpet with which it covers the bottom of the nest-cavity. A day or two later, in my vineyard near by, I found where a piece of heavy twine that held a young grapevine to a stake had been pulled down to the ground and picked and beaten, and parts of it reduced to its original tow. Here, doubtless, the birds had got some of their carpeting material. I recently read in a work on ornithology that the rings of small holes which we see in the trunks and limbs of perfectly sound apple-trees are made by woodpeckers in search of grubs and insects. This is a hasty inference. These holes are made by woodpeckers, but the food they obtain at the bottom of them is not the flesh of worm or insect, but the flesh of the apple-tree—the soft, milky inner bark. The same writer says these holes are not hurtful to the tree, but conducive to its health. Yet I have seen the limbs of large apple-trees nearly killed by being encompassed by numerous rings of large, deep holes made by the yellow-bellied woodpecker. This bird drills holes in the sugar maple in the spring for the sap. I have known him to spend the greater part of a bright March day on the sunny side of a maple, indulging in a tipple of maple sap every four or five minutes. As fast as his well holes filled up he would sip them dry.
