Dry climates can make life difficult for birds when the soil is parched and there is very little food to be foraged. You can help by putting high-fat seeds or a cup of dry dog food inside your birdfeeder. The rule of thumb, according to the Humane Society, is simple: Never give human food; but dog food is totally fine. It contains ingredients birds crave, and if it gets a little wet, it becomes mushy enough for them to eat. Of course, never leave too much food out in a feeder for too long. Replace, wash and keep clean.
