@florymonde, a person who knows the weight of a bat to the nearest gram is someone I can trust. Are you a chiropterologist by trade, or just a keen hobbyist? Anyhow I thought that the wingspan of a bat would be too wide to be swallowed, but it's possible that at the last moment he/she curled up in a sort of panicked…

@TexasTroy and @rodneyderrick - thanks for the advice. This sounds about right to me too, so I have added "Random Insect" to the public food database with 80 calories and 10g of protein.

@klpleet2011: 250 kcal sounds like a lot. I mean it probably only had 2-3 thimble-fulls of "meat". Is the exo-skeleton mostly protein? I don't know. Since you say "guesstimate" I assume you're not a professional in this area but I thank you for your attempt.
