I wish our whole yard, back and front, was xeriscaped. It's so dry here in Northern Colorado this spring that it will take way more water to green things up than we should be using. Hopefully we'll get a little more rain in the next couple of months.
The birds are suffering. Our robins are having trouble getting to the worms that sustain them. If I water one of the trees or a patch of flower garden, the birds will flock to that wet spot and cock their heads, listening for the sound of movement underground. Even the mourning dove was cruising the ground under the finch feeder this week, looking for stray bits of thistle seed.
Xeriscaping wouldn't solve the birds' problems but at least the yard would look good without wasting water.
