_Fall migration._--In the British Isles from mid September to end November (early dates, August 12, 1910, Norfolk; August 20, 1910, Essex; August 1, Norfolk). Heligoland (September and October); also met with in practically all European countries, reaching south Spain (November, end October, or early November). In Asia recorded from Asia Minor, Transjordania (October), arriving Sind (early October) and India (September-October).
_Casual records._--Once recorded from the Faeroes (1910); also on Madeira (March 15, 1889); Andaman Isles (once), as well as on the Pribilof Isles.
_Egg dates._--June 4 to 12 (2 records); 14 to 21 (8 records); 22 to 30 (2 records); July 1 to 14 (3 records); 15 to 28 (4 records); 29 to August 2 (2 records).
The dowitcher, or, as I should prefer to see it called, the red-breasted snipe, occurs as a species entirely across the American continent. The long-billed dowitcher, the western form, was originally described as a distinct, full species; it has since been reduced to the rank of a subspecies, because of very evident intergradation; and now some very good ornithologists are in doubt as to the propriety of recognizing the two varieties in nomenclature at all, because no distinctly different breeding ranges for the two forms have been established, and typical (so-called) eastern birds have never been found breeding anywhere. What few breeding birds have come from Alaska and northern Mackenzie all seem to be _scolopaceus_, but _griseus_ may still be found breeding there when we have larger series. I have had considerable correspondence with Prof. William Rowan about the breeding dowitchers of Alberta, including interchange of specimens. He seems to think that the Alberta birds are constantly distinct from either _griseus_ or _scolopaceus_ and perhaps worthy of a name. It seems to me that they are strictly intermediate and should not be named. In a letter recently received from P. A. Taverner he seems inclined to recognize the Alberta bird as a "short-billed bird resembling the eastern most, but intermediate, and with spotting characters different from either."
On migrations, and in winter, both forms are found entirely across the continent. The best that can be said is that _griseus_ is more common on the Atlantic and _scolopaceus_ is more common on the Pacific coast. Dr. Louis B. Bishop, with whom I have discussed this question, is inclined to call one a mutant of the other; he has some 200 dowitchers in his collection, from all parts of the country, those from the Atlantic and Pacific coasts being about equally divided and the two forms being about equally represented. In analyzing his series, taking into account length of bill, length of wing and brightness of color, he finds that: of _griseus_, 86 per cent are from the Atlantic coast, 2 per cent from the interior, and 12 per cent from the Pacific coast; and of _scolopaceus_, 14 per cent are from the Atlantic coast, 30 per cent from the interior, and 56 per cent from the Pacific coast. While collecting near Pasadena, California, on April 25, 1923, he shot into a large flock of dowitchers and picked up nine birds, all but one of which were typical _griseus,_ in bill, wing, and color.
