Since Saturday’s weather was lousy for photos, and I didn’t get any decent ones Sunday, I’ll go with field notes from the weekend concerning Nashville Warbler Underside pattern.
I have previously covered this topic and with migration getting into swing, now is a good time to review. Especially since I personally haven’t done it lately…
Saturday morning while out with Mike, I spotted a small bird that never gave a good overall look. The view was from below and not for long. I’ll make a disclaimer I did see one other ID which I’ll discuss later.
First off, I was pretty sure it was a warbler with an outside shot at being a vireo.
The underside pattern from head to tail:
- Bright Yellow throat and onto the breast.
- White Belly.
- Bright Yellow undertail coverts.
With an unique pattern I thought the ID would have been straight forward. On to Sibleys – Eastern North America for a quick look to confirm. Or so I thought.
A quick look through the vireos didn’t produce a match. And a quick run through the warblers didn’t either. So a slower look was in order.
What we missed was Nashville Warbler underside matches that description but the drawing doesn’t show as much white as I saw on the belly. We simple overlooked it. But as far as I can tell it is the only Eastern Warbler matching that pattern.
Now back to the disclaimer. I had the advantage of seeing a bright eye ring. But I didn’t want to use until I was sure from the underside pattern.
Review Warbler Underside Patterns
Now is the time. I’ll once again reference the chart shown in the first sentence post. It’s from Dunn and Garrett’s Warblers. Taking 15 minutes with it will pay dividends in the field. The other thing is to go through your favorite field guide and look for the underside patterns. There are a few unique patterns that are distinguishable but knowing which are yellow or white, or darker tail colors, will help eliminate species in the field.
