They're still here as of yesterday when I saw two of those awesome little creatures! I do worry about them...Texas is not the best place to migrate through this year. By the end of the summer, insects were practically nonexistent. But some returned in fall...I know the hummers need the protein from small insects to fortify them for the rest of their migration. And of course, I kept my hummer plants going the best I could. Fortunately, the Flame Acanthus is still blooming pretty good...that surprised me, thought it would be done by now. Thanks for the article...excellent! BTW, I notice that Texas is tied for number of hummingbird species with Arizona...at 18!
