his song while perching; but on calm sunny days he rises 

 from his perch to sing, singing as he rises, and then drops 

 back to his favorite rock still singing. Often a pair of 

 males appear to engage in competitive antiphonal concert, 

 and then the mountain-side rings with ecstatic melody. 



Along in August, when the midnight sun no longer 

 glorifies the North, the snow-buntings don their warmer 

 buff and brown plumage, and begin to assemble in consid- 

 erable flocks on the grassier slopes for the journey south- 

 ward. Quiet and still, as if sad to leave their northern 

 home, they feed about tlie rocks, lingering even until No- 

 vember, when the night comes on, and the sun no longer 

 shines even at noonday. Then the North is silent until 

 they come again.

Family MNIOTILTI DAE— Wood Warblers. 

 This family lives upon foliage insects; a few, however, have 

 flycatcher habits. They come late and 'leave early. Field observa- 

 tion is rarely dependable because there are so many kinds, and 

 these kinds have many variations; the immature ones differinj:;', 

 in many cases, from the mature in plumage. Then, too, for most 

 part, they keep to the tree tops. The data for most species is 

 based on museum records. Many seen in field but positive iden- 

 tification not possible for above reasons. 



636. Mniotilta varia — Black and White Warbler. 



A fairly common summer resident. Field and museum records 

 give May 1, 3, 5, 9. Lane County, September 14, one specimen. 



637. Prothonofaria citrca — Prothonotary Warbler. 



This warbler is a common summer resident in eastern Kan- 

 sas wherever swamps are found. Field observation May 1. It is 

 quite likely that they arrive considerably earlier. They probably 

 return south in July and a few, if any, remain till September. 

 Last museum records August 6, 11, 13. 

 639. Helmitheros vcrynivorus — Worm-eating Warbler. 



A rare migrant. One museum record May 6.
