General behavior: Semi Social. A single Night Stalker will have a large range that it patrols. However, with the volatile nature of Enigma Prime, and the constant need to move away from volcanically affected areas have left the species very tolerant when one or more other Night Stalkers enter its territory. Thus although generally you will only see a single one in a given area. It is not uncommon for areas closer to seismically active areas to contain several as the interlopers move through trying to scratch out a new territory for themselves.
As hunters, they are extremely aggressive. Using the cover off night to hide their massive bodies, they rely on echo location to hone in on their targets. So beware the clicks and cherps at night! Although nocturnal, lights do not affect them as much as one might think. Though a spotlight right into its face in an otherwise blackened night, will temporarily stun the creature. But even that will only work for so long till it gets used to the new light source.
Night Stalkers tend to sleep during the day, and usually can be found roosting along the many massive cliff sides that dominate the planets landscape. Using the sheer height and drop offs as protection while they rest.
Unlike many winged animals, they do not have a set breeding ground. Being reptilian in nature, they give birth to clutches of 3-5 eggs which hatch within 30-35 local days. Within 90 days, the hatchlings have grown large enough to leave the nest. At which point the parents no longer care for them. In fact, if the little Night Stalkers don't beat a hasty retreat, they might find themselves on the menu.
Also because they are reptiles, they can be found more along the equatorial regions of the planet where it is warmer. Their black coloring also helps them to absorb the heat from the stars and thus help them stay active even during colder periods. A particularly cold snap will push them into an almost hibernation like state until they are able to warm up again. In this state, their bodies slow almost to a stop so as to use very low amounts of resources to stay alive.
