I tend to think of Pine Warblers as the most likely warbler candidate at a feeder. Last week, a migrating Pine Warbler enjoyed eating the Bark Butter middle out of a Stackables sandwich at a feeder not 10 feet from my house. I've also had them in my yard eating at a seed tray and eating suet.
The Pine Warbler that visited last week seemed intent on seeking out high fat suet. Besides the Bark Butter, it also tried to access suet in the suet log feeder. It was probably working hard to add weight for its migratory journey by feasting on high fat foods like suet.
Jim's Birdacious Bark Butter has been eaten by 7 species of warblers across the country.
- Orange-crowned Warbler (rare in NY)
- Northern Parula (common in NY)
- Yellow-rumped Warbler (common in NY)
- Townsend's Warbler (not found in NY)
- Yellow-throated Warbler (rare in NY)
- Pine Warbler (common in NY)
- Ovenbird (common in NY)
I guess I'm lucky because I've had both the Pine Warbler and an Ovenbird eat Bark Butter in my yard. Ovenbirds are somewhat common visitors to the wooded side of my yard, where they'll come up the gentle slope to within feet of the house. I occasionally put Bark Butter at the base of a few trees in that area - low to the ground where Ovenbirds forage for food.
