THE OOLOGIST 



take poultry and game birds, but tbeir 

 usefulness is so great that the good 

 work they do far overbalances the 

 harm. The following species are more 

 or less plentiful in this region: Red- 

 tailed hawk, red-shouldered hawk, 

 broad-winged hawk, and sparrow 

 hawk. Two of these, the red-shoulder- 

 ed and broad-winged hawks are less 

 common than the others and will not 

 here be described. 



The red-tail is the largest and best 

 known species. It may often be seen 

 sailing gracefully over the fields and 

 woods in search of its favorite prey. 

 Its food consists to a great extent of 

 harmful animals, particularly field 

 mice and groundmoles. Every farm- 

 er knows the work of these mammals, 

 and a bird which destroys them should 

 surely receive his protection. 



The little slender-winged, long-tail- 

 ed sparrow hawk is also abundant and 

 is doubtless well known to most farm- 

 ers. It does no harm and is particular- 

 ly valuable in destroying mice, moles; 

 harmful insects and great numbers of 

 that pest the English sparrow. 



We regret confusion in the number- 

 ing of the issues of this volume of

O. C. C. Nicolls, Capt. R. G. A. at St. 

 Georges, Bermuda, wishes his corres- 

 pondents to note the fact that the 

 postage on a letter to Bermuda is five 1 

 cents instead of two. That he is under 

 orders to leave there, and unless cor- 

 respondents see that the proper 

 amount of postage is attached, there' 

 will be delay and annoyance in hav- 

 ing the mail forwarded.

A Correction. 



"Nesting of the Western Horned 

 Owl in Central Alberta" is the heading 

 given to my article in the January is- 

 sue of THE OOLOGIST. This is wrong- 

 as anyone will see by reading few lines 

 of the episode. The heading ought to 

 be "Nesting of the Western Horned 

 Owl in Northern Manitoba."
