“At this time, when the young birds are able to care for themselves, the pairs no longer keep alone together, but, leaving their nesting-haunts, travel about either in a family party or in larger friendly flocks, and, although some birds, like the Song Sparrow and Meadowlark, sing throughout the season, the general morning chorus and the nesting season end together, in early or middle July. “It is quite difficult to name the birds when young and old travel in flocks, for when a male is bright-coloured and the female dull, the first coat of the young is often such a mixture of both that it is easily mistaken for a wholly different and strange bird. “In August or September almost all of our birds change their spring feathers. This is called moulting. And the brightly coloured birds often drop their wedding finery for dull-coloured travelling cloaks, so that they may not be seen when they fly southward through the falling leaves. “After this season Father Tanager, of the scarlet wedding coat with black sleeves, appears in yellowish-green, like his wife, and the little Tanagers sometimes have mixed green, yellow, and red garments, for all the world like patchwork bedquilts pieced without regard to pattern.

But in early spring he will change again, and, before the nesting time, reappear among us with every black feather polished free from rusty edges and glistening as of old. “When Father Tanager comes back, he is brave and red again, though it takes little Tommy Tanager two moultings to grow an equally red coat. “Even with the more quietly marked birds their colours are less distinct after the summer moult, so that what is known as the bird’s perfect or typical plumage is in many species that of the nesting season alone.” “I didn’t think that there was so much to know about birds; they seem to have ways of doing things just like people. I’d love to know all about them every Friday, but I suppose that’s too nice to happen,” said Sarah Barnes, as Gray Lady paused and moved her chair back from the bright light that was now shining through the door directly in her face, for the clouds had rolled away down behind the hills, leaving one of the clear, bright, early September afternoons when the sun lends its colour to the field of early goldenrod, until sunset seems to reach to one’s very feet.
