| 説明 | This one bank of the Missouri River in North Dakota is loaded with sand martins (aka bank swallows), Riparia riparia, and their holes in the bank. However, I didn't notice until I uploaded the photos that there is a single cliff swallow, Petrochelidon pyrrhonota, among them. I can't explain it. Is he mistaking them for his own kind? Is he there for the safety in numbers? You'd think he'd be off with some other cliff swallows or something. As for the martins, if you think they're blurry now you should see me trying to get shots of them flitting over the water catching insects. It's impossible, I swear. |
