of their favorite food, the fruit of the poison ivy, at least a 

 few flocks of Myrtle Warblers are present in the thick timbered 

 sections of the bluff regions and bottom lands. In some win- 

 ters, as in 1914-15 and 1915-16, these birds are to be found in 

 noticeable numbers during the most severe weather conditions. 



The migrants begin arriving from the 16th to 25th of March 

 and by the middle of April are present in large numbers 

 throughout the entire county. Very few are seen after the 

 first week in May though an occasional straggler lingers until 

 rather late in the month (May 20, 1916, latest). 



The earliest fall birds reach here from September 27th (1908, 

 earliest) to late in the first week of October, and by the last of 

 the month the migrants are gone and only winter numbers are 

 present. 



These warblers may be looked for during migration in any 

 wooded place. They pass through Swope Park in great num- 

 bers and are found along the boulevards and about lawn shade 

 trees. They are restless birds but often feed low down in the 

 trees and in bushes and are easy of approach. 



DENDROICA MAGNOLIA (Wilson). Magnolia Warbler. 

 Regular but rather uncommon migrant. 



The Magnolia Warblers pass through at the height of the 

 spring migration between the llth and 16th of May. No fall 

 records are available but the returning migrants should be 

 looked for during the second and third, and possibly fourth, 

 weeks of September. They may be found in the tall trees along 

 the rivers and creeks, and even in the hawthorn and crab 

 thickets of the outer residence districts. 



The greatest number ever noticed in one year was on May 

 14, 1917, when more than ten birds were seen between Inde- 

 pendence and Courtney (Tindall). 



DENDROICA CERULEA (Wilson). Cerulean Warbler. 

 Common migrant and not uncommon .summer resident. 



The first Cerulean Warblers are usually heard on May 1st, 

 rarely before (April 29, 1900, earliest), and sometimes not un- 

 til the last days of the first week of May. They leave early for 

 the south, not being seen usually after late August. As they 

 haunt the tops of the highest trees they are more often heard
