turn flight from the 10th to 25th of September. They are never 

 numerous. They are to be looked for in wooded places beloved 

 of the warblers. Several records have been made in Swope 

 Park. 



DENDROICA DOMINICA ALBILORA. Sycamore Warbler. 

 Not common migrant; probable summer resident. 



This region is on the western edge of the range of the Syca- 

 more "Warbler, and though it is a regular migrant and very 

 possibly a more or less regular summer resident, it has not been 

 often noted. 



This warbler is one of the first to appear in spring, being 

 preceeded only by the Myrtle Warbler. The earliest available 

 record is April 7, 1918 (mouth of Indian Creek). 



The Syeamore Warbler is a frequenter of tall trees in bottom 

 land along water courses. It is difficult to see in the tree tops, 

 but is distinctively marked and has a very characteristic song, 

 the manner of delivery of which recalls the Indigo Bunting. 



DENDROICA VIRENS (Gmelin). Black-throated Green Warbler. 

 Not common migrant. 



The Black-throated Green Warbler is present during the first 

 three weeks of May and during all of September. It is never 

 present in very great numbers. 



It may be looked for in the wilder parts of Swope Park, in 

 the Dodson region and in the timber of the Missouri and Blue 

 Valleys. 



DENDROICA VIGORSI (Audubon). Pine Warbler. 

 Regular but not common fall migrant. 



The Pine Warbler is regularly seen here between September 

 3rd and October 16th, during which time it is often in full song. 

 It is given as a fall migrant only as it has never been observed 

 here in spring. This is perhaps merely an oversight as it mi- 

 grates north through /eastern Kansas and eastern Missouri. 

 Students should be on the lookout for this bird in the spring in 

 the hope of establishing a new record. 



Some recent records are: Sept. 3, 9 and 10, 1914 (singing), 

 Sept. 9, 14, and 15, 1915 (singing), Sept. 10, 1916, and Oct. 

 16, 1916.
