Young broods of swallows began to appear this year on July the eleventh, and young martins (hirundines urbicae) were then fledged in their nests. Both species will breed again once. For I see by my Fauna of last year, that young broods come forth so late as September the eighteenth. Are not these late hatchings more in favour of hiding than migration? Nay, some young martins remained in their nests last year so late as September the twenty- ninth; and yet they totally disappeared with us by the fifth of October.
How strange is it that the swift, which seems to live exactly the same life with the swallow and house-martin, should leave us before the middle of August invariably! while the latter stay often till the middle of October; and once I saw numbers of house- martins on the seventh of November. The martins and red-wing fieldfares were flying in sight together; an uncommon assemblage of summer and winter birds.
A little bird (it is either a species of the alauda trivialis, or rather perhaps of the motacilla trochilus) still continues to make a sibilous shivering noise in the tops of tall woods. The stoparola of Ray (for which we have as yet no name in these parts) is called, in your Zoology, the fly-catcher. There is one circumstance characteristic of this bird, which seems to have escaped observation, and that is, that it takes its stand on the top of some stake or post, from whence it springs forth on its prey, catching a fly in the air, and hardly ever touching the ground, but returning still to the same stand for many times together.
I perceive there are more than one species of the motacilla trochilus: Mr. Derham supposes, in Ray's Philos. Letters, that he has discovered three. In these there is again an instance of some very common birds that have as yet no English name.
