Every once in a while we will see a gila monster, a desert kingsnake, a western diamondback rattlesnake, a bobcat, a coyote, a javelina etc. There are birds we expect to see every day: mourning & white winged doves, gambel's quail, curved bill thrasher, cactus wren, goldfinch, house finch, cardinals, pyrrhuloxia, phainopepla, gila woodpecker, and a wide variety of LBBs. Every once in a while we will see a hooded oriole, a brown crested flycatcher, a black tail gnatcatcher, a ladderback woodpecker, a gilded flicker, etc. Yesterday, was not every day --- nor was it a "once in a while" day. Yesterday, there were a pair of Mallard Ducks! Yes, sitting by the pool wondering why there wasn't plant food in the pool to eat. After a while they were content to just sit and sleep. At some point -- didn't see it -- they must have flown away. It was a special day.
