I figure with the winter rain we got, everywhere is an oasis so migrants aren't dependent on the oasis. Which is good. But they would still come in to water, so probably the south winds have encouraged them to keep moving. And possibly we're getting a late migration and more migrant waves will appear. Hummingbirds are coming in more often since the ocotillo finished blooming.
I've only got 2½' of water left in the tank so hopefully it'll rain before July, or at least enough showers so I won't have to haul water to keep things alive. I think I'm good to go, but do get nervous this time of year when the tank gets low. Water is my security.
