1. Bats are extremely territorial.
They may occasionally permit you on their territory; if you get this rare opportunity, be sure to appreciate it! Remember, though, that just because you have been allowed once, doesn't mean you will be again! You need specific, explicit permission for each time you wish to enter a Bat's territory.
2. Bats are gregarious.
They may sometimes try to convince you they are solitary; don't believe them! Bats, though they sometimes have difficulty interacting with other species, are extremely social animals. As well as having a complex social structure, nearly all hero teams of note have been led by at least one Bat at one time or other (often multiple different Bats).
3. Bats have a rigid dominance heirarchy.
If you see a submissive Bat being treated in what seems to you like an unfair fashion, your hero instincts may impel you to try to get between them. Resist this temptation! This is normal Bat behaviour and is accepted by both parties. If you try to interfere, they will both turn on you!
4. Bats are dominant when relating to other species.
Though a Bat may be submissive to another Bat, never expect one to submit to you. If one is in your group, expect it to be alpha. If a Bat gives you an order, tuck your tail between your legs and obey. If you don't the Bat will feel that it has to exert its dominance. Besides - the Bat is almost guaranteed to be telling you the right thing, anyway.
5. Bats are nocturnal.
Though they will often try to force themselves into diurnal patterns in order to relate to other species, this is not natural for them, and causes them stress. A Bat is at its best in the dark, and if you wish to observe one, this is the best time.
Always remember: Bats are wild animals! No matter how well-trained one might seem (see: subspecies: common name: 'Nightwing') they are still unpredictable. Use caution whenever you are around a Bat.

You are inconceivably lucky that I intercepted this email.
Also, you have approximately 5 minutes before the alpha Bat arrives at your place of residence.
