NXJMBEE OP SPECIES. 13 



In the spring of 1910 Mr. Walter G. Savage moved to Delight, 

 Pike County, and at once began to make observations on the birds 

 of that region. His notes, based in many cases on specimens which 

 he collected, have added much to our knowledge of the birds of the 

 southwestern part of the State. In the winter of 1910-11 Mr. 

 G. Dallas Hanna spent about six weeks at Van Buren collecting 

 birds, chiefly the smaller land birds. His specimens have been 

 examined and identified by the Biological Survey, and these records, 

 together with his notes on 65 species, have added 11 forms to the 

 State list and many new facts on the distribution of winter birds. 



Most of the information on breeding ranges contained in the 

 present report was gained by the writer during a collecting trip 

 extending from April 28 to July 7, 1910. The principal localities at 

 which observations were made are as follows: Mammoth Spring, 

 Cotter, Lake City, Walker Lake (Mississippi County), Turrell (Big 

 Creek Station), Stuttgart, McGehee, Wilmot, Camden, Delight, 

 Womble, Mena, Rich Mountain (Polk County), Pettigrew, and 

 Conway. 



Several other members of the Biological Survey staff have visited 

 the State for short periods. Edward A. Preble collected at Fort 

 Smith and Fayetteville from September 15 to October 1, 1892. 

 B. H. Dutcher worked at Hardy, BatesvUle, Beebe, and Benton in 

 April, 1894. C. E. Brewster visited Big Lake for a few days in No- 

 vember, 1909, and December, 1910, and Wappanocka Lake (Turrell) 

 on December 20, 1910. W. L. McAtee collected from November 12 

 to 24, 1910, at Mud Lake (St. Francis County), Wappanocka Lake, 

 and Menasha Lake and made observations at Big Lake from June 

 20 to 23, 1911. 



NUMBER OF SPECIES. 



In the list which follows 255 species and subspecies are accredited 

 to the State. No bird is admitted to the list unless there is an 

 actual record of its occurrence, based on a specimen, a published 

 record, or a report by a competent observer. 



On account of the very limited number of observers many species 

 have escaped detection which, by reason of their known range in 

 adjacent regions, must certainly occur in the State. These species, 

 35 in number, are included in a hypothetical list, distinguished from 

 the species actually recorded by being printed in smaller type. 



Dividing the list of birds actually and probably occurring in the 

 State into several categories, we find that 67 species or subspecies 

 may be considered as permanent residents, either nomnigratory 

 birds breeding within its limits or migratory species that occur 

 in both summer and winter; 75 are summer resident breeding spe- 

 cies; 60 are winter residents; 69 are transients — that is, migrating 

 species occurring in either spring or fall; and 19 occur irregularly as
