In Montagu's "Ornithological Dictionary," under the article "Song of Birds," there is the following remark: "Regarding the note of alarm which birds utter on the approach of their natural enemies, whether a Hawk, an Owl, or a Cat, we consider it to be a general language perfectly understood by all small birds, though each species has a note peculiar to itself." I was last April very much pleased at witnessing an illustration of the truth of this opinion. I found a nest of young Throstles at the root of a hazel, and although they could scarcely fly, yet as they were near a footpath, and the next day was Sunday, when many idle and mischievous lads would be rambling about, I thought they would be safer out of their nest than in it; and as I knew that when so far fledged, if they were once disturbed they would not continue in the nest, I took one from the nest and made it cry out, and then put it back again; but in one minute, not only it but its three companions had disappeared in the long dry grass which was round about. On hearing the cry of their young one, the parent bird set up such shrieks of alarm as brought all the birds in the wood to see what was the matter. I noticed the Blackbird, the Chaffinch, the Titlark, the Robin, the Oxeye (greater Titmouse), the Blue and Marsh Titmouse, and the Wren all uttering their cries of alarm and apprehension; even the golden-crested Wren, which usually seems to care for nothing, was as forward and persevering as any of them in expressing its fears on this occasion; indeed, the only bird which seemed indifferent to all these manifestations of alarm was the Creeper, which continued its anxious and incessant search for food, as it flitted from one tree to another, examining them from root to branch without ever seeming to understand or to care for what seemed to have so much frightened the others. (June 30th, 1832.) * * * * * DATES OF THE APPEARANCE OF SOME SPRING BIRDS IN 1832, AT CLITHEROE. Young Rooks heard, 5th April; House Martin seen, 14th; Sandpiper, 14th; Willow Wren, Spring Wagtail, and Redstart, 17th; Wheatear, 19th (this is generally the first spring bird seen); Sand Martin and Swallow, 22nd; Cuckoo heard, 26th; Wood Wren, Blackcap, and Whinchat, 28th; Mocking-bird and Whitethroat, 4th May; Swift, 7th; Flycatcher, 11th; and Fieldfares were not seen until the 2nd of May, which is later than I ever observed them before. (In the parish of Allesby, near Coventry, Fieldfares were observed as late as the 14th of May.) No doubt many of these birds were in the neighbourhood earlier than the dates I have attached to them, but they are the periods at which I saw or heard them.
