REVEW5 Report on Scottish Ornithology in 1920, including Migration. By Evelyn V, Baxter and Leonora J. Rintoul. (Reprinted from The Scottish Naturalist, 1921, pp. 105-120, and 135-158.) THIS report, which is in its usual concise and useful form, contains a great deal of interest and importance. The year 1920, in fact, was quite a notable one for Scottish Ornithology. A large number of occasional visitors was reported, especially from Lerwick, which seems fast becoming a second , but of greater importance was the attempted nesting of the Bee-Eater and the nesting of the Brambling, a new nesting-place of the Gannet and the extension of the Fulmar, all of which have already been reported in our pages. Many occurrences of rare visitors, however, are here reported for the first time and of the most important of them we give brief particulars below. The whole report provides a most excellent summary of observations in in 1920, and. it is very seldom that anything is missed in these reports, so that we may mention for the sake of completeness that occurrences of Blackcaps and Continental Robin at S. Uist and of Great Spotted Woodpeckers in Inverness-shire in 1920, recorded in our pages (Vol. XIV., pp. 117 and 276) appear to have been overlooked. NORTHERN BULLFINCH (Pyrrhula p. pyrrhula).—This bird has been recorded from the northern isles in most autumns or winters during, recent years. It was frequently reported from Lerwick () between January 13th and March 20th, a female is noted on October 21st, and on Fair Isle there were three on October 28th, while one is recorded at Kergord, Weisdale (Shetland) on May 3rd—an unusally late date. ORTOLAN BUNTING (Embenza hortulana).—Single birds are reported from Noss Head (Caithness) on May 3rd and 4th, Fair Isle on the 5th and Lerwick on the 3rd, and on November 16th. RUSTIC BUNTING (E. rustica),—One was obtained near Lerwick on October 6th. RICHARD'S PIPIT (Anthus r. richanli),—One is reported from Fair Isle on October 2nd. TREE-PIPIT (A. t. trivial/is).—Passage-migrants at Fair Isle and Lerwick in April and May. BLUE-HEADED WAGTAIL (Motacilla f. flava).—One at Fair Isle on May 12 th and 15th. SO BRITISH BIRDS. [VOL.

RED-BACKED SHRIKE (Lanius collurio).—-One at Lerwick on August 22nd. RED-BREASTED FLYCATCHER (Muscicapa p. parva).—Several are reported from Lerwick, viz., single birds on September 23rd, October 7H1 and 8th, and two on October 9th, while there were several at North Ness on October 7th.

ICTERINE WARBLER (Hippolais iclerina).—One is reported from Noss Head (Caithness) on May 3rd. Though the bird has occurred several times in the northern islands this is, we believe, the first record for the mainland of Scotland. BARRED WARBLER (Sylvia n. nisoria).—-One at Lerwick on August 29th and another on September 16th. GARDEN-WARBLER (S. borin).—One at Noss Head on May 12th is stated to be the first record of the bird in Caithness, others at Lerwick in May, August, September and October. LESSER WHITETHROAT (S.

RED-NECKED GREBE (Podiceps griseigena).—Two at Loch Ryan (), where there was a great assemblage of Grebes (including many Great Crested, a number of Slavonian, several Little and one Black-necked) on December 4th. STOCK-DOVE (Columba mnas),—One at Fair Isle on April 26th and two on November 6th. BLACK-WINGED STILT (Himantopus himantopus).-—As the Stilt has very rarely occurred in Scotland, it is curious that two should have appeared in one year, one being reported here (p. 108) as seen at Scatfield on the Moray Firth on May 18th, while another was recorded in our pages (Vol. XIV., p. 164) at Loch Ryan, on the other side of Scotland on October 17th. IVORY-GULL (Pagophila eburnea).-—One at () on May 20th.
