247. Sialia sialis. Bluebird. — Resident in portions of Concho Coun- 

 ty. Very common in spring and fall. They wander considerably after 

 January 1, in search of berries, which are very scarce. Associates fre- 

 quently with the two next. A nest was found in a hole in an old stump 

 in July, 18S2, with four eggs. Young in spotted plumage shot through- 

 out August. 



24S. Sialia mexicana. Western Bluebird. — Rare winter visitant. 

 Shot in flocks of the common Bluebird in Concho County. 



249. Sialia arctica. Mountain Bluebird. — Rare until the fall of 

 1SS6, when it appeared in immense flocks, and was very unwary, feeding 

 with Cedarbirds and other species on the numerous wild berries in Octo- 

 ber and November. Some of the males were nearly ultramarine; others 

 in the same flock were various shades of blue. None seen since January 

 10, 18S7. 



Addenda. — 250. Rallus elegans. King Rail. — One seen in South 

 Concho, in the spring of 18S6, by Mr. Cope, who tried to catch it with a 

 dog. 



251. Pandion haliaetus carolinensis. Osprey. — Several pairs breed 

 on South Brady, according to Mr. Cope. 



252. Chordeiles virginianus henryi. Western Nighthawk. — Rare 

 on the Plains ; probably breeds. 



253. Spizella monticola ochracea. Western Tree Sparrow. — Com- 

 mon in small flocks, winter of 1884-S5.

ADDITIONS TO THE AVI-FAUNA OF BAYOU 

 SARA, LA. 



BY CHARLES WICKLIFFE BECKHAM. 



In the 'Bulletin of the Nuttall Ornithological Club' for July, 

 1SS2, I gave an annotated list of the birds of Bayou Sara, Louis- 

 iana, the result of five days' work during the month of April of 

 that year. Eighty-six species were enumerated. Since then I 

 have had an opportunity of making further observations at the 

 same place ; extending over a much longer period, from April 1 

 to April 28, and am able to add twenty-seven species to the fauna 

 as heretofore given. 



The weather during the period mentioned was exceptionally 

 dry, both for the season and the locality, which fact doubtless
