Didn't know orioles ate nectar too? And purple finches? What do they eat? I found that Goldfinches are happy with Sunflower seed. So much cheaper than thistle! Just saw one hummer! Tried the nectar but then came to the window to stare at the cactus flowers! Did I maybe put water instead of nectar in the feeder - was good enough for them every other day! I'm going to wash and refill, too. Kinda like when we re-thread and re-bobbin out machines when they don't work!
