New strains were continually introduced. So loud 

 and full were some of his notes that " the blue air 

 trembled with his song," and the woods fairly woke

 less vocalization. It was bird opera music of the 

 highest style, improvised for the occasion, and formed 

 a fitting conclusion to this rare birds' gala-day.
