On the night of the 8th we had a few migrants on the lantern, ten blackbirds--three only of which were males--and three fieldfares. Several of them appeared much fatigued, and after a few preliminary hops round the lantern, settled down on the lee side to have a nap. A fresh breeze blowing at the time, those still on the move were frequently hustled by the wind against the sleepers, who, thus rudely awakened, vigorously resented what they no doubt considered a deliberate attempt to assault, with the result that all hands were at times engaged in a battle royal; the hen “blackies” only engaging with those of their own sex, while the cocks and fieldfares tackled all comers indiscriminately. It was rather amusing to witness the finish between a pair thus engaged. Edging round the narrow pathway in their struggle, they gradually came under the influence of the wind sweeping round the lantern, when suddenly one of them would be wheeled off its feet away into the darkness, its opponent peering after it in evident astonishment, and probably congratulating itself on its prowess. The haze, responsible for their appearance here, clearing after midnight, before 3 a.m. they had all resumed their journey shoreward. On the 20th, a pair of grey crows passed, going east, and on the 22nd a heron was seen travelling in the same direction. Again, on the night of the 27th, three hen blackbirds and a starling had the lantern all to themselves. The white whelks have now gone into winter quarters, and only a few are to be seen lingering among patches of immature mussels. The black edible whelk, or periwinkle, whose vegetarian habits demand a more inshore life, is here conspicuous by its absence. Occasionally, during the summer months, a very close search reveals a few solitary specimens. Two different varieties of slugs have been much in evidence among the rocks here of late. One of them (_Doris coccinea_), resembling in shape and colour a section of an orange, I have already described; the other somewhat resembles the common snail. Furnished with anterior horns and fleshy spines, ranged along the back, it curls itself up when out of water like a hedgehog. Earlier in the season they were mostly of a beautiful bluish colour, now they appear quite red. Without any visible means of defence, one can fancy these shell-less molluscs furnishing a delectable tit-bit for a hungry cod.
