A May Day Horizon. 31 



A MAY-DAY HORIZON. 



Readers of the Bulletin are only too familiar with the 

 editor's and Dawson's "All Day with the Birds." They 

 come with annual regularity. It has been a perpetual dis- 

 appointment that no one else seemed interested to "go and 

 do likewise." Each locality has its own peculiar conditions 

 more or less favorable to the birds during their migrations. 

 Would it not be worth the effort to know what the maximum 

 of bird life in one day is in your locality.'' For most localities 

 that maximum comes between the 25th of April and the 

 15th of May, for a series of years, depending, of course, 

 upon the latitude of the place. For northern Ohio it seems 

 to fall close to May 8th. The editor would be greatly 

 pleased to receive so-called May-day horizons from every 

 reader of this notice. Let it be understood that such a 

 horizon may be taken at any time during the warbler migra- 

 tions in late April or early May, and let it be an all day 

 horizon. The birds are too numerous during that time to 

 make a census of them; besides that would waste valuable 

 time. Plan well in advance to devote one whole day to the 

 birds during the coming spring migration, and report your 

 success. A number of such pieces of field work would prove 

 interesting and instructive to readers of the Bulletin. Plan 

 the territory to be covered, and work over such parts of it as 

 may be necessary to learn in advance where some of the less 

 common breeding species may certainly be found. The ed- 

 itor would be glad to give whatever of his experience might 

 be helpful in making this special effort. It is a long time 

 before May, but a resolve made now will carry that far. Ex- 

 perience has proved to me that such a supreme effort is 

 worth more than can be communicated in words.
