Helinaia chrysoptera, Linn. 
PLATE CVII. — Male and Female. 
Although I have met with this species entering the United States from 
* the Texas in the month of April, and have procured several specimens in 
Kentucky and Louisiana, as well as a single one in New Jersey, I never had 
the good fortune to find its nest. When it first makes its appearance in 
Louisiana or Kentucky, it usually resorts to the higher branches of trees, 
where, amid the opening leaflets and blossoms, it actively searches for its 
insect food, occasionally following its prey on wing to some distance, and 
moving by short leaps among the twigs, in the manner of Helinaia 
carbonata, which, in its elongated and slender shape, it in some measure 
resembles. The flight of this species is, unlike that of the Cape May 
Warbler, Sylvicola maritima, elevated, swift, and irregularly undulated, 
until it is about to alight, when it dives towards the spot selected by it, as most 
Warblers are wont to do. I never saw a bird of this species in autumn, and 
therefore infer that its southward journey must be accomplished in a very 
•secret and careful manner, or by night. A male and a female are figured in 
their perfect spring plumage.
