研究表明，在一个系统中，多达8只雌性可以产卵，一个系统可能有长达24米的相互连接的地下隧道，这些地下隧道有多个通往地表的开口，深度可达一米。其中两个系统比其他系统更复杂，尽管它们没有包含更多的卵窝。这些系统可能代表不止一个季节的使用。每只使用多个洞穴系统的雌性似乎和独自筑巢的雌性一样多地挖掘，但公共洞穴系统中的巢穴更深，可能受到更好的保护。
showed that up to 8 females may lay eggs in one system and that a system may have up to 24 meters of interconnected underground tunnels with multiple openings to the surface and reach depths of a meter. Two of the systems were more complicated than the others though they did not contain more clutches of eggs. These systems probably represent more than a single season of use. Each female using a multiple burrow system seems to do as much digging as does a female nesting by herself but the nests in a communal burrow system are deeper and probably better protected.
