To this I append a note from Mr. Stevenson, giving an account of a similar migration of the bird to the coast of Norfolk :-— oe : “The Golden-crested Wren is very common in Norfolk throughout the year, nesting in the fir-plantations and shrubberies. That these fairy-like little creatures brave the perils of a sea-voyage in autumn, and, leav- ing more northern countries, swell the numbers of our usual visitants, there can no See be any doubt, oe their frequent appearance on the coasts at such seasons in an exhausted state, and the fact oo specimens being picked up dead at the foot of our lighthouses, having flown, with other nocturnal migrants, oo Hee oped wns dows,‘dazzled and attracted by the glare of the lamps. The most striking instance, however, of ‘luce migration in large numbers was witnessed by my friend Captian Longe, of Great Yarmouth, on the morning of the 2nd of November 1862. He says, in a letter to me, ‘As I was walking to Hemsby, about 7.30, when it was just daylight, about half a mile out of Yarmouth, on the Caister road, my attention wea attracted toa sure bush overhanging the marsh-dyke which borders the pathway, by the continuous twittering of a small bird. On looking closely, I found the bush, small as it was, literally covered with Golden-crested Wiens: There was hardly an inch of twig that had not a bird on it; and even from my rough attempt at calculation at the time, I feel sure there were at least between 200 and 300. Most of them were either females or young birds, having a /emon-coloured crest. They were perfectly tame; and although I sat down on the other side of the ditch within six feet and watched them for some time, they did not attempt to fly away; but one (or more) would occasionally rise off its perch and hover like a Butterfly, and settle again in some other position. I went the next morning to look for them, but they were all gone: the wind had been easterly, with much fog.’ Ihave lately seen the spot where this flight had settled themselves before proceeding inland, and found it close to the sandhills which run parallel with the coast, and not more than two or three hundred yards from the sea-beach.” It would be highly interesting to ascertain whether these migrants return again in the spring to the countries whence they came, like the Redwing and Fieldfare ; or whether these vast accessions are due to some extra- neous cause, such as an unusual severity in the season prompting them to seek a more genial clime, or an undue increase in the number of individuals, rendering the removal of a portion of them necessary for the general welfare. It is surely due to one or other of these causes; for how ill-adapted is this little bird for the performance of so long a journey without the chance of a rest by the way! The subject is indeed a mystery, and most puzzling to us all. Independently of England, this bird inhabits Europe generally, the northern portions of Africa, probably the Himalayas, China, and Japan ; at least Golden Crests which closely resemble our own birds inhabit those countries. The nest of the Golden-crested Wren is as beautiful as the bird that makes it. A fine example, taken by myself at Loudwater, on the 2nd of May 1858, from the sunny side of a silver spruce, was formed of green moss, masses of cobwebs, and little patches of wool, warmly lined with soft feathers; it was sus- pended to the underside of a branch by numerous filaments, apparently composed of spiders’ webs and fibres of wool; in form it was nearly spherical, but much flattened at the top, the upper edge being pressed inwards, as it were, so that the aperture was considerably smaller than the interior, which measured 34 inches, while the opening was barely 13. This nest contained eight eggs, of a delicate pearly salmon-colour, minutely freckled at the larger end with ochre-brown in the form of a zone. The young birds, when they leave the nest, have no trace whatever of the golden crown ; at the second moult, however, these feathers begin to appear, and are fully assumed by the end of the ensuing autumn, when the crown of the female becomes lemon-, and that of the male rich yellow. To give a description of so common a bird would be superfluous when it is accurately portrayed on the opposite Plate, and I shall have to point out wherein it differs from the Fire-crested Wren (Regulus igni- capillus) in my account of that species. The Plate represents two males, a female, and a nest on a branch of the Silver Fir, all of the natural size.
