One of the places we stoped during our last travel was the Oregon Dunes National Recreation Area to spend some time with our friend Glenn. I spent an afternoon with him during his volunteer time on the Oregon Dunes Overlook Loop Trail. He showed me a place along the trail where the Rufus Hummingbirds could be seen everyday. The above photo is a female Rufus at that very location. We saw three birds there twice during our hike. What they come to pick up on the trail there is a mystery. You can see small pieces in her bill. Is it grains of sand? If it is, what would be the purpose? I don't think it would be used in nest construction, nor can I imagine its use in their diet. Is is small seeds? Glen sees them every day and only in this location. If any readers out there have an idea, please leave a comment.
