Harris — Birds of the Kansas City Region. 317 



marked birds but are difficult to see as they feed among the 

 dense foliage of the highest tree tops. 



They breed in the Missouri and Blue Valleys and may be 

 commonly found in Swope Park during summer. 



One form of the song of this species is similar to that of the 

 Cerulean Warbler but may be distinguished by a difference in 

 the opening notes, which are more drawled in the song of the 

 Parula. 



Dendeoica tigbina (Gmelin). Cape May Warbler. 

 Very rare migrant. 



The only known records of the occurrence of this warbler in 

 this vicinity are May 22, 1909, May 11, 1911, May 11, 1912 and 

 April 26, 1915. The record for May 11, 1912, was made over 

 the state line in Johnson County, Kansas. ' 



Dendroica aestiva aestipa (Grmelin). Yellow Warbler. 

 Very common migrant and common summer resident. 



The Yellow Warbler arrives regularly during the last five or 

 six days of April. During early May when the bulk of the 

 migrants are present, they are distributed over the entire county. 

 This species is most numerous in the Missouri bottomis between 

 May 2nd and 7th when it may be said to fairly swarm in the 

 wiUow thickets. It also prefers to nest in the bottom lands and 

 in the wide valleys leading into these regions. It has never 

 been found in Swope Park in summer but there is one breeding 

 record for the lower Brush Creek region not far to the west. 



It is not seen in this county after the first week or ten days 

 in September. 



[Dendeoica caerulescens caerulescens (Gmelin). Black- 

 throated Blue Warbler.] 

 Probable migrant. 



This warbler has been reported several times to the east and 

 west of this district but there is no known instance of its oc- 

 currence in the immediate vicinity. Students should be on the 

 lookout for this distinctively marked species during migration 

 times. 



Dendeoica coronata (Linn.). Myrtle Warbler. 

 Very common migrant and rather rare winter resident. 



During favorable winters when there is an abundant supply
