E. The sight of small but entire fish excites the newly hatched 

 skimmer much more than does macerated fish. Terns are not so 

 excited until after the first week. 



F. The action of pecking is instinctive to a certain extent, 

 but is acquired very slowly in this way. By imitation it is learned 

 quickly and is performed successfully within a few minutes. 



G. Flight is wholly instinctive, the terns learning the use of 

 their wings as soon as the primaries are large enough to support 

 them. 



BACHMAN'S WARBLER BREEDING IN LOGAN 

 COUNTY, KENTUCKY. 



BY G. C. EMBODY. 



Bachman's Warbler (Helminthophila bachmani) first came 

 to my notice April 26, 1905, when two birds, from their song, were 

 mistaken for Worm-eating Warblers. They were feeding in a 

 maple tree situated in a high, dry wood about ten miles northeast 

 of Russellville, Ky., quite an unusual place for bachmani, but of 

 the right sort for vermivorus. 



Although the surrounding country was searched for a likely 

 breeding ground, none was found nor were more warblers seen. 



My field work was continued the following spring (1906) and 

 on May 14, I came upon a swamp fairly swarming with warblers, 

 if one were to judge from the great confusion of songs. 



These, one by one, disentangled themselves to my ear into the 

 songs of the Cerulean, Parula, Kentucky, Hooded, Black and 

 White, and Blue-winged Warblers and Redstart. But at frequent 

 intervals there were faint trills which in the open might have 

 passed by as coming from the Chipping Sparrow. I counted 

 several of these coming from as many directions and decided that 

 there were Bachman's Warblers about. 



The first song was traced to its source only a short distance away
