Warbler Nation
October 4, 2025
It’s really fall out there with leaves crunching underfoot, and that welcome autumn fragrance in the air. There are still plenty of great invertebrates out there, and the spiders seem to be especially busy.
Marbled Orb Weaver
A caterpillar that I see every October, the Laugher Moth caterpillar. I find the face intriguing, and the hair, well, it’s a “do” and a don’t together. They are somewhat non-touch. It won’t sting you like a Saddleback caterpillar, but the long hairs can irritate the skin.
Northern Parula (summer resident) just hasn’t moved on yet.
Chestnut-sided Warbler. (migrant) I love the color they take on in winter. The back is a gorgeous shade of chartreuse
I checked the pantone chart just to be sure, and it is indeed bright chartreuse
Here’s a male Chestnut-sided in spring breeding color. They undergo a dramatic transformation as the seasons change.

Cape May Warbler (migrant)
Cape May
It takes some courage to visit a bathing spot, where a bird is vulnerable to predation. Cape May on left, and Bay-breasted Warbler on the right. Warblers often arrive in mixed flocks.
Philadelphia Vireo (migrating). Most years, we are surprised and delighted to see a rare Philadelphia passing through, but this year, we have good numbers of Philadelphias stopping by in the Piedmont. When you see these common names, you might think the Philadelphia Vireo breeds in Philadelphia, but that never seems to be the case. Some naturalist from way back just saw the bird for the first time somewhere, and attached the name. The Philadelphia Vireo breeds in southern Canada, and northern New England.
Nashville Warbler (migrant). Nashvilles breed in Canada and the Northeastern US, and have another breeding ground in the Pacific Northwest. Again, someone saw one passing through Nashville, and there you have the name.
Blackburnian Warbler, named for Anna Blackburne,(English) who was the sister of the naturalist (Ashton Blackburne) who found one of these warblers in NY, sent it home to the UK, where naturalist Thomas Pennant assigned the name. Anna herself was a well known naturalist, but had no particular interest in New World birds. How could you not have any particular interest in New World birds, especially our eastern warblers?
A curious reaction. This Blackburnian (fall plumage) was gleaning for caterpillars. He had eyes on the green and cream caterpillar in the lower right corner, dug around a bit, and then simply backed off. I wonder if the spider web was too thick in the same area as the caterpillar, but after a long bit of attention, the warbler flew off sans caterpillar and gleaned for other insects and caterpillars.
Right now, there are plenty of Magnolia Warblers passing through
and I never tire of photographing them.
I’ll keep looking up, as fall migration continues. Special thanks go out to Birdman Bart M, who located the beautiful mixed flock of warblers featured in much of this post.
So long from Brumley and Jordan Lake.
Love,
