General Notes. 93 



The editor spent four days — May 9 to 12 — in company with Mr. 

 George L. Fordyce, of Youngstown, Ohio, studying the birds. The 

 first two days were spent at Youngstown, where 116 species were 

 recorded on the 9th, and 113 on the 10th. An overland automobile 

 ride to Vermilion on the 11th and a study of the birds along the 

 shore of Lake Erie on the 12th. completed the pleasant studies. 

 The warbler migrations were at their height at Youngstown on 

 the two days spent there, but did not reach the lake shore until 

 more than a week later. 



It has been suggested that the publication of May Day horizons 

 would be valuable as showing the progress of the migrations the 

 country over, as well as indicating the distribution of the birds. 

 The editor would be pleased to receive expressions of opinion 

 upon this point. He is entirely ready to give space in the Bul- 

 letin to such lists which give evidence of careful work, and be- 

 lieves that such a movement is worth while. 



This is the time of year when breeding habit studies ought to 

 be undertaken more generally. It is not difficult to find a nest, 

 and it is not a serious task to give the whole of several days in 

 the study of the feeding habits of many species of birds. Most 

 of the sparrows, the wrens, and many others, permit so close an 

 approach that even a blind is not necessary for close observation. 

 One may sit in comfort while observing the feeding habits of the 

 Field or Song Sparrow, for instance. Try it and prove or dis- 

 prove this assertion.

WINTER BIRDS OF NORTHERN McKENZIE COUNTY, 

 NORTH DAKOTA. 



These notes are from November, 1912, to March, 1913. The 

 north line of McKenzie county is the Missouri River and south 

 from the river is a collection of breaks, hills, cut-banks, gulches, 

 ravines, creeks and coulees, which extend for about six miles, ex- 

 cept along the larger creeks, where the adjacent land is more or 

 less undulating. Between the creeks are broad stretches of level 

 farming land. On the prairies there are no trees except what has 

 been planted by the settler from about eight years ago. 



On the Missouri River bottom are to be found groves of Cotton- 

 wood, Elm, Ash, Box-alder and Willow, with a mixture of Buffalo- 

 berry, Plum and Choke-cherry trees. In the breaks and gulches
