Ted et al,
The existence of this Worm-eating Warbler is mentioned twice in the original "Two days left..." post, so the total remains a robust 15, yes?
What I want to know is why the Worm-eating is sitting in the midst of honeylocust pods. It might be getting adult Honeylocust Seed Weevils (Amblycerus robiniae). Note the emergence hole of one of these weevils in a pod at right in the photo. These "pea weevils" are not true weevils but are in the family Bruchidae. The members of this family are noted for their feeding on various legume seeds (aka "beans" or "peas"). While I don't know the Honeylocust Seed Weevil's life cycle, nor can I find reference to it on-line, I do know adults sometimes come inside houses during winter. I have observed this both in Fort Collins and Lamar. This would lead one to assume they emerge outdoors sometime in autumn or early winter, prior to seeking overwintering sites in protected locations. If adult emergence is on-going in Grand Junction, perhaps the warbler will persist, and be "gettable" by local birders, if they search concentrations of honeylocust pods in the area of the report. Just a guess. If anyone sees the warbler getting a seed weevil, or sees seed weevils among the pods, we'd all like to hear about it. Email me in private if you get a sample of same (or something else) that could be verified. Thanks.
Even though Black Friday shouldn't count as a real day, except for birders brave/sane enough to use it properly, there is now only 1 day left to add the remaining 41 species of NA warblers not yet seen in CO in November.
