There is a common notion that animals are better meteorologists than men, and I have little doubt that in immediate weather-wisdom they have the advantage of our sophisticated senses (though I suspect a sailor or shepherd would be their match), but I have seen nothing that leads me to believe their minds capable of erecting the horoscope of a whole season, and letting us know beforehand whether the winter will be severe or the summer rainless. I more than suspect that the clerk of the weather himself does not always know very long in advance whether he is to draw an order for hot or cold, dry or moist, and the musquash is scarce likely to be wiser. I have noted but two days' difference in the coming of the song-sparrow between a very early and a very backward spring. This very year I saw the linnets at work thatching, just before a snow-storm which covered the ground several inches deep for a number of days. They struck work and left us for a while, no doubt in search of food. Birds frequently perish from sudden changes in our whimsical spring weather of which they had no foreboding. More than thirty years ago, a cherry-tree, then in full bloom, near my window, was covered with humming-birds benumbed by a fall of mingled rain and snow, which probably killed many of them. It should seem that their coming was dated by the height of the sun, which betrays them into unthrifty matrimony; "So priketh hem Nature in hir corages;"(1) but their going is another matter. The chimney swallows leave us early, for example, apparently so soon as their latest fledglings are firm enough of wing to attempt the long rowing-match that is before them. On the other hand the wild-geese probably do not leave the North till they are frozen out, for I have heard their bugles sounding southward so late as the middle of December. What may be called local migrations are doubtless dictated by the chances of food. I have once been visited by large flights of cross-bills; and whenever the snow lies long and deep on the ground, a flock of cedar-birds comes in mid-winter to eat the berries on my hawthorns. I have never been quite able to fathom the local, or rather geographical partialities of birds. Never before this summer (1870) have the king-birds, handsomest of flycatchers, built in my orchard; though I always know where to find them within half a mile. The rose-breasted grosbeak has been a familiar bird in Brookline (three miles away), yet I never saw one here till last July, when I found a female busy among my raspberries and surprisingly bold. I hope she was _prospecting_ with a view to settlement in our garden. She seemed, on the whole, to think well of my fruit, and I would gladly plant another bed if it would help to win over so delightful a neighbor. (1) Chaucer's _Canterbury Tales, Prologue,_ line 11.
