I have been much interested this spring at witnessing in two or three instances the tenacity with which the Marsh Titmouse sits on its nest. Being in a wood near my own house, I perceived a pair of these birds in one of the trees, and having seen them in the same place several times before, and being desirous of finding the nest, I sat down to watch their motions. After examining me on all sides with much chattering and many gesticulations, indicative of dislike and suspicion, the female flew to the root of a tree, three or four yards off, and disappeared, as she had gone to the opposite side of the tree to that on which I sat; and as there were several holes about the root I was at a loss to know in which the nest was built, and began to strike the root with a stick, expecting her to fly out, but nothing appeared. I then examined the holes one by one, and whilst doing so heard her hissing and puffing from within, in such a way that if I had not known she was there I should have thought it was a snake rather than a bird. However, as she would not come out, and the hole was so small that I could not get my hand in, I was obliged to raise the siege until next morning, when I returned armed with a hammer and chisel with which to storm her citadel. As the wood was sound, the hole small, and the nest six or eight inches within the tree, I was five or ten minutes before I could get to it, during which I gave her repeated opportunities of escaping if she chose; but she still sat on her nest, puffing and pecking at the stick that I thrust in in order to drive her off. She at last crept to the further edge of the nest, which I then took out, as I wanted it for one of my friends who is a collector of eggs, but on attempting to blow one I found they had been sat upon too long, and I then felt desirous of seeing whether the old bird would hatch them after having her nest torn from under her, and I turned back to the tree whence I had taken them, and found her still sitting in the hole where I had left her. I regret to add that the humane part of my experiment did not succeed, for although she remained after I had returned the nest to its place, she left it immediately after, and did not return to it again.
Another instance which I witnessed was in a nest containing young ones. This was also at the root of a tree, but the situation did not appear to be so well chosen as is usually the case with the Titmouse tribe; for in this instance the hole went quite through the tree, and on one side was large enough to admit the hand. As the young ones were exposed to the weather, and were also liable to be seen by anyone going along the adjoining footpath, I attempted to remedy this defect by covering the larger hole with a sod, which to a casual observer would appear to have grown there. On taking the sod off one day, to see how the nestlings were going on, I perceived that a clod of earth had fallen from the sod upon them, and I took a stick and hooked it out, lest it should smother them. Whilst I was doing this I perceived the old one sat on the further side of the nest, so still and quiet that until I perceived her eye I fancied she was dead; and she also endured several pokings with the stick before she would move, although the hole on the opposite side of the tree enabled her to escape whenever she thought proper.
Perhaps Mr. Rennie, in his next edition of Montagu's Dictionary, will give us a new name for this bird, as the one it has at present is no more applicable to this species than it is to the _Parus caeruleus_, or the _Parus major_, and not half so much so as it would be to the _Parus biarnicus_; and he has changed good names into bad ones with far less reason, witness _Corvus frugilegus_ into _Corvus predatorius_. The former name is strictly applicable to that species, and to that alone; and so useful a bird does not deserve the name of a thief. The Chaffinch (which received its name of _Coelebs_ from Linnaeus on account of the males alone remaining in Sweden in the winter, which fact is corroborated by White, who found scarcely any but females in Hampshire during that season) has had its name changed by Mr. Rennie into _Spiza_. The old name is characteristic of a remarkable fact in the habits of this bird; why the new one is more appropriate (neither understanding Greek, nor having read Aristotle), I cannot say. Will Mr. Rennie condescend to enlighten me?
Once for all--if we are to have a new nomenclature, let a committee of able naturalists decide upon it, or let us submit to the authority of a master (for instance Linnaeus or Temminck), but don't let every bookmaker who publishes a work on Natural History, rejecting names long established and universally received, give new ones in such a way as serves only to show his own presumption and to confuse what it ought to be his business to elucidate.

CREEPER.
The Nuthatch does not occur in this, and I doubt if in any part of Lancashire, but the Creeper is very common, and is a bird with the habits and peculiar call of which I have been acquainted from my childhood. Mr. Bree, who combines with accurate and extensive information, an amiable and pleasant manner of communicating it, has not, I perceive, witnessed the Creepers associating with the Titmice in winter, at which I am rather surprised, and think if they are numerous in his neighbourhood, he will hereafter not fail to perceive them among the small flocks of Titmice which associate through the winter.
