silent. Immediately after twelve the light improved, and the "tack tack" of a Ring Ouzel was heard. The influence of continuous daylight upon the routine of bird-life in the far north is worthy of further study. On July 25th we noted the Ring Ouzel on the top of a rocky bluff near Svolvaer.
Phylloscopus trochilus.—We share Mr. Aplin's view as to the Willow Wren being the most numerous bird at Tromsö. In mid-July many pairs were feeding young which had just left the nest. But the song was to be heard daily all through the month, while in this country the bird is silent for about three weeks before recommencing with its quiet summer song early in August. Thus I noted that the Willow Wren was still singing at Svolvaer on July 25th, and again at Bergen on the 30th.
Sylvia atricapilla.—On July 13th a Blackcap was singing in a sheltered gully on the lower slopes of Flöifjeld. Its presence seemed in keeping with the luxuriant vegetation of this favoured spot. Birch and mountain-ash hung from the steep banks of the little ravine, where water from the melting snow-patches above trickled over sheets of moss, amongst which grew Parnassia, Geum rivale, and quantities of that delicate and beautiful fern, Cystopteris montana. There were patches of a tall white-flowered umbellifer, and the rest was a rank jungle of meadow-sweet, wood-cranesbill, great valerian, and the blue alpine sow-thistle. The only sound beside the Blackcap's song was the note of a Northern Marsh Tit, which was busily investigating the rotten birch-stumps, some of which showed the marks of its bill. And all this in the latitude of Disco Island, and far north of Iceland! On the morning of the 17th I heard another Blackcap at Lyngseidet.
Parus borealis.—The Northern Marsh Tit was ranging the woods in family parties. The usual call is the familiar "chee chee chee" of our own bird, but on Grindö one puzzled me for a time by making use of a fresh note. In many places this species had been pecking and digging into the old birch-stumps.
Muscicapa atricapilla.—I saw a male Pied Flycatcher perched on a rail at Lyngseidet early on the morning of the 17th.
M. grisola.—Its note called my attention to a Spotted Flycatcher at the same time and place as the last. Lyngseidet would appear to be a favourite locality with the smaller birds.
