>>...so it is not uncommon to see several colonies in rocky areas together where natural cavaties are with water nearby, while the flats with just grasses and few trees have few bees as few nesting areas available... Do you find any colonies nesting in abondoned ground burrows in the flat areas? I assume there is some forage/water in the flats.
