No rare migrants have been noticed, but this was scarcely to be expected. In this respect the budget of notes supplied by that veteran ornithologist Herr Gätke bears a striking contrast to our east coast reports. On that small island, so favourably situated for observation, Mr. Gätke has trained up quite a host of practical observers, and any rare visitant will have to be very sharp if it succeeds in escaping detection. Quoting from Mr. Gätke's letter dated Dec. 22nd, we have, on Sept. 17th, _Sylvia fuscata_, though not got; _Anthus Richardi_ on the 18th; _A. cervinus_ on the 20th; _Picus leuconotus_ on the 21st; then some days S.W. with rain and no birds; 26th, calm and clear, _Emberiza pusilla_; 27th, E.N.E., _Anthus Richardi_, _Emberiza pusilla_ (two shot), _E. aureola_ (seen); 28th, _E. pusilla_ (two seen), _E. rustica_ (one shot); 29th, _Sylvia superciliosus_ (one); 30th, _Emberiza pusilla_ (one); Oct. 1st, _E. pusilla_ (one); Nov. 2nd, 3rd and 4th, westerly winds and nothing, but daily some _Parus ater_; on the 5th, again, _Anthus cervinus_ (seen and heard); northerly winds, sometimes N.E. on the 8th, a Leaf Warbler seen at close quarters, but not procured by Aeuckens, the Heligoland birdstuffer, which Mr. Gätke feels tolerably certain was a very rare visitant; the same day there were two or three _E. rustica_, and one each of _A. pusilla_ and _A. cervinus_. The rare Leaf Warbler was again seen on the 9th, but could not be obtained; an _Emberiza rustica_ was also seen. On the 10th, _E. pusilla_ shot and _E. rustica_ seen. On the 12th, _Muscicapa parva_ and _Motacilla lugubris_, which latter comes there rarely in autumn. On the 14th, _Sylvia superciliosus_ was shot by Mr. Gätke's eldest son, and two more were seen by Aeuckens in a garden where shooting was not permitted. On the 18th, one very fine _E. pusilla_ shot. On the 20th _Lestris affinis_ was seen close by, but not shot, as it would have fallen in the sea and drifted away. This is the third, if not the fourth, known occurrence of the Siberian Herring Gull at Heligoland. On the 24th a large Redpoll was shot, which Mr. Gätke thinks can only be the Greenland bird, _Linota Hornemanni_. A summary of the various returns show that four species, Larks, Starlings, Rooks and Hooded Crows, in the order given respectively, far outnumber any other, and of these four the Lark far exceeds the rest in migratory numbers. As a rule, the lines of migration followed have been from E. to W., or S.E. to N.W. direct on to the English coast. To the middle of October we find birds rarely coming from points north of east; after this date they appear to come occasionally from directions north of east, between east and due north. The line of migration of the _Anatidæ_ has been from north to south, crossing the line of the _Insessores_ at right angles.
