It will be seen that the Mourning Dove and Mocking- 

 bird were found on practically every single census. The 

 former were missing on two trips, the tirst at noon in Mc- 

 Clain County where they were seen a weelc later on re- 

 peating the trip and the second on the noon census of 

 July 3rd which has made so nuiny exce])tions. ^Locking- 

 birds were recorded on all but two censuses; one in the 

 Wichita Mountains and the other in the Arbuckles. Tliese 

 two are the most ada]>tabk^ of all our native bii-ds here; 

 ^Mockingbirds are found about farmhouses on tl'.e ])rairies 

 and cabins in the woods, wliile tlu' Mourning I )ov( is even 

 more universal in its tastes for it will live in dee]) woods, 



* In central and western Oklahoma the Mockingbirds and Lark 

 Sparrows were the western forms but near the Arkansas border 

 the birds were probably the eastern forms, according to informa- 

 tion kindly given me by Dr. H. C. Oberholser. The Horned Larkp 

 were " Desert " in central Oklahoma but may have been "Prairie " 

 in the east. The Meadowlarks were all eastern except those in 

 Kingfisher County on the second census which were western.
