Rh Wherever it may happen to be placed, the nest is large and well secured. It is composed of dry leaves, grass, and moss, which are con- nected internally with a thick layer of mud and roots, lined with pieces of straw and fine grass, and occasionally a few feathers. The eggs are from four to six, of a beautiful bluish-green, without spots. Two broods are usually raised in a season.

The young are fed with anxious care by their tender parents, who, should one intrude upon them, boldly remonstrate, pass and repass by rapid divings, or, if moving along the branches, jerk their wings and tail violently, and sound a peculiar shrill note, evincing their anxiety and displeasure. Should you carry off their young, they follow you to a Con- siderable distance, and are joined by other individuals of the species. The young, before they are fully fledged, often leave the nest to meet their parents, when coming home with a supply of food. The family of Robins which I have grouped in the plate exhibits such an occurrence. During the pairing season, the male pays his addresses to the female of his choice frequently on the ground, and with a fervour evincing the strongest attachment. I have often seen him, at the earliest dawn of a May morning, strutting around her with all the pomposity of a pigeon. Sometimes along a space of ten or twelve yards, he is seen with his tail fully spread, his wings shaking, and his throat inflated, running over the grass and brushing it, as it were, until he has neared his mate, when he moves round her several times without once rising from the ground. She then receives his caresses.

Many of these birds shew a marked partiality to the places they have chosen to breed in, and I have no doubt that many who escape death in the winter, return to those loved spots each succeeding spring.

The flight of the Robin is swift, at times greatly elevated and capable of being long sustained. During the periods of its migrations, which are irregular, depending upon the want of food or the severity of the weather, it moves in loose flocks over a space of several hundred miles at once, and at a considerable height. From time to time a few shrill notes are heard from different individuals in the flock. Should the weather be calm, their movements are continued during the night, and at such periods the whistling noise of their wings is often heard. During heavy falls of snow and severe gales, they pitch towards the earth, or throw themselves into the woods, where they remain until the weather becomes more favourable. They not unfrequently disappear for several days from a place where they have
