Here is what A. C. Bent wrote about the Northern Parula in “Life Histories of North American Wood Warblers” (1953).
It creeps along the branches and hops from twig to twig, often clinging to the underside of a cluster like a chickadee, an action that led some of the early writers to refer to it as a small titmouse.
In fact, the name Parula means little titmouse or chickadee.
I was able to take these photographs of one at Col. Sam Smith Park showing the bird in fall plumage.
This is a tough one as the photo does not show the complete head. I will identify it at the end of the post.
The white wing bars, yellow belly and black stripes identify a Magnolia Warbler.
Sweet melody amidst the moving spheres
Breaks forth, a solemn and entrancing sound,
A harmony whereof the earth’s green hills
Give but the faintest echo; yet is there. – Bessie Parkes
