Ecology of the Basilisk lair

I’m writing an short adventure for 5e, and need to know what other types of creatures would live near a wild basilisk lair, and why?

I’m looking for D&D-specific ecology content. Dragon magazine had an Ecology Of… series. Otherwise, relevant 1e/2e/3e/3.5e content would be great.

Another option could be wild basilisk lairs in existing D&D products, so I can get a feel for how these creatures are handled.
