"For days we stayed there waiting for the entire company to gather. At length on one of the blue October days we flew southward.
"There were hundreds of birds in the flock. We looked like a small cloud, as we skimmed and darted through the air. As we flew, the flock was a half mile long.
"We spent the winter in South America. There are delicious insects there. But for all that we love the north country best.
"By and bye Mother Nature whispered to us. She said that it was nest-building time in the northland. Such a twittering and fluttering there was when this news came.
"That very afternoon we started north. Day after day we flew. We met other great flocks as we travelled, who joined us.
"Day after day we flew northward. We did not stop to eat, but caught our food on the wing.
"Now we lunched on moths and flies. Again we dined on grasshoppers. Any insect foolish enough to trust itself in the air at the time we passed served as food.
"We arrived here only a few days ago. It is not yet very warm, but here under the eaves on the sunny side of the barn it is quite comfortable.
"We are so busy with this nest-building and settling for the summer. You see we swallows do not live alone. There are always flocks of us together.
"We should be lonely if we lived only in pairs. That is the reason that we build a whole little village of nests under your eaves."
