We observed the first lizards to emerge—including whiptails, zebra-tailed and spiny lizards. And now we’re seeing plants blossom and birds nest! A beautiful male Costa’s Hummingbird is coming to our feeders and doing its whirring territorial song and dizzying display flight.
Curve-billed thrashers are nesting in a big cholla cactus. Baby birds can be heard in a Lesser Goldfinch nest high in a palo verde. And a House Finch pair has a nest with three eggs in it, all hidden deftly in another cholla.
