178 Bird- Lore Warbler, - and 'What Can We Call the Incubation Period,' by Ora W. Knight; Migration Reports for 1895, reports on the status of the Bluebird in Maine during the past spring, from which it appears "that in most places Bluebirds are as plentiful as they were last year, while in some localities they are reported scarce," and ' Notes ' from various parts of the state. We read with pleasure the editor's state- ment that "the progress of bird study in Maine'during the past two years has been great. Everywhere there has been an awakened interest in ornithology, and there are now ten times as many bird students as formerly." For the September issue, W. H. Brown- son supplies a graphic description of a visit to 'The Tern Colony of Bluff Island, ' which in June he estimated to contain over one thousand birds. Frank T. Noble describes his experience with a wounded Pintail, which "was discovered on the bottom, grasping with its bill the tough stem of a cowslip." There are migration reports from members and a very interesting sketch, by Walter H. Rich, of a captive White- winged Scoter, whose portrait serves as a frontis- piece to this number. O. W. Knight writes on 'Some Birds of Pleasant Ridge,' Ruthven Deane sends 'Notes from Scarboro Beach,' and items follow on various birds. Notice is given that the annual meeting of the Maine Orni- thological Society will be held in Portland, at the rooms of the Portland Society of Natural History, on Friday and Saturday following Thanksgiving Day. — F. M. C. The Warbler. — The second number of the second volume of 'The Warbler,' pub- lished May 1, 1906, contains colored figures of the eggs of ' 'Empidonax griseus canes- cens" and of "Empidonax insulicola" but since Mr. Grinnell has shown that this alleged island form is inseparable from Empidonax difficilis (Condor, VIII, 1906, 74), we may accept the figures as represent- ing a Santa Barbara Island set of eggs of that Flycatcher. Mr. Grinnell writes on the nesting habits of the first-named Empidonax, which he found to be "fairly common in July on the higher portions of the San Gabriel Moun- tains in the vicinity of Mount Waterman," but we are assured that this careful student is not responsible for the slip which, both on the plate and in the heading to his text, makes Empidonax canescens read "Empi- donax griseus canescens." P. B. Peabody writes of the breeding habits of the Pifion Jay as he found it in Wyoming, and accompanies his article with three photographs, one of which shows this Jay brooding. The third number of this volume of ' The Warbler,' published August 20, figures in color the eggs of Bicknell's Thrush and of the Salt Marsh Yellow-throat, and contains an illustrated study of the Rocky Mountain Nuthatch, by P. B. Peabody ; ' Long Island Bird Notes,' by John Lewis Childs; the ' Nesting of the Roseate Spoonbill in Flo- rida,' by R. D. Hoyt; the ' Gnatcatchers of Southern California,' by Harry H.Dunn, and ' The Chuck-Wills-Widow,' by Anne E. Wilson. The Wilson Bulletin. — The Wilson Bulletin for June, the second number of the eighteenth volume of this standard publica- tion, contains a capital article on the habits of the Common and Roseate Terns, which we can commend to field workers, not only for its contents, but as an object-lesson in methods of field study. The Common Tern has been studied by many ornithologists in a more or less desultory fashion, but Mr. Jones' additions to our knowledge of the habits of this species show the importance of concentration of effort. Other articles are ' A Preliminary List of the Birds of ,Seneca County, Ohio,' by W. F. Heninger, which enumerates 203 native and 2 introduced species; ' Remarks on the Summer Birds of Lake Muskoka, Ontario,' by B. H. Swales and P. A. Taver- ner; 'Two All-Day Records in Northern Ohio,' by Lynds Jones, Notices of Recent Literature, etc.
