Carnivorous Canaries

Habitat
Normally found in abandoned mine shafts but they have been encountered in some forests near empty homes. Possibly ones that once belonged to mages who practiced summoning.

Biology
Have the appearance of a canary with bright yellow feathers but often with spots that are stained and darkened by blood. Their beaks are filled with razor sharp teeth and have the strength to bite through leather and living beings - sometimes even portions of wood. While they can sometimes appear partially decomposed, they are incredibly determined and swift flyers. They have been known to attack and chew their way through a target whenever possible but will leave it behind as soon as it is dead, leaving behind much of the corpse. The reason why is unknown, but perhaps the gruesome little creatures just enjoy the sound of other beings in pain. Thankfully, their bodies are still weak and easy to destroy with most weapons - as long as one can manage a hit on them. Strangely, once this devil is killed its remains will revert back to that of an ordinary canary - often rotten and partially decomposed but ordinary and lacking the typical pool of black blood.

Sociology
They are extremely hostile little beings that will attack any living being that gets its attention. When one of these devils is around, there’s a high chance others of its kind will follow. The smallest flock of these that has been encountered was a group of three, but they have been seen with much, much larger groups.

Trivia
Some to believe they are reanimated remains of canaries that were once used to warn miners of toxic air.
