NOTES ON THE BIRDS OF LEON COUNTY, FLORIDA — 

 THIRD SUPPLEMENT. 



BY R. W. WILLIAMS. 



In ' The Auk' for October, 1904 (XXI, p. 449) I published a pre- 

 liminary list of the birds of Leon County, Florida. This included 

 156 species, all then positively known to occur in the county. In 

 April, 1906, 17 species were added bringing the total up to 173 

 (Auk, XXIII, p. 153). The list was still further extended by 

 the addition of 9 species in my article of April, 1907 (Auk, XXIV, 

 p. 158), increasing the total to 182. 



During the seven years since the publication of the last article^ 

 10 species have been added to the list. These are Horned Grebe 

 {Colymbus auritus), Herring Gull {Larus argentatus), Bonaparte's 

 Gull {Larus Philadelphia), Buffle-head Duck {Charitonetta albeola). 

 Pectoral Sandpiper {Pisobia maculata), Duck Hawk (Falco pere- 

 grinus anatum), Short-eared Owl {Asio flammeus), Purple Finch 

 {Carpodacus purpureus purpurcus), and Junco {J unco hyemalisy 

 subspecies?) 



These additions bring the list of species now known to occur in 

 the county up to 192. 



Some further observations of interest have been made upon a few 

 of the species included in former articles. These observations, to- 

 gether with the data respecting the 10 additions above stated, are 

 here recorded. 



The species now added to the list are numbered serially begin- 

 ning with the number following the last in the preceding article. 

 The last number, therefore, is the total of species so far recorded 

 in the county. 



List of Species. 



183. Colymbus auritus. Horned Grebe.— Probably a regular 

 winter resident bmt not abundant. I identified two on December 7, 1908,. 

 in the possession of a negro who had killed them on Lake Jackson and was 

 peddling them along with some wild ducks. 



184. Larus argentatus. Herring Gull. — I have never seen this 

 species in the county and believe its occurrence to be sporadic, if not.
