In the desert can there be anything more important than a water source? Probably not. When we bought our house one of our first tasks was dismantling a rather unattractive fountain in our backyard, part of which I re-purposed as a bird bath.
It didn't take long for word to get out that there was a new bar in the neighbourhood and for all the local 'chicks' to start hanging out there! I think the Cactus Wren would be a punk rocker :)
Then there is a bit of local colour provided by the finches
An occasional visit from the impeccably groomed but rather shy White-crowned Sparrow
But you better keep on the right side of the local bouncer, he makes sure that no ones behaviour gets too rowdy!
