THERE is something distinct and well-bred about this demure exquisite, 
and the day which discovers one searching the willow tops with genteel 
aloofness is sure to be underscored in the note-book. The marks of the 
spring male are as unmistakable as they are regal: a bright yellow breast 
and throat contrasting with the ashy of cheeks ad head, the latter shade 
relieved by a white eye-ring, and surmounted by a chestnut crown-patch.
