One of my all-time favorite novels, Anansi Boys by Neil Gaiman, includes an anecdote: a crow's call wakes up someone who's sleeping outdoors, just as a large cat (a tiger, perhaps) is sneaking up on him. One character suggests the crow was trying to warn the man. Another posits the bird was bringing the sleeper to the tiger's attention so it could enjoy the scraps after the meal. |

But also, on a tangent, there is a bird that does this kind of non-conspecific alarm calling the time as part of its food-gathering strategy: the African fork-tailed drongo.
The drongo gives true alarm calls to food-rival species nearby, to tell them when it has spotted a mutual predator. This leads to these food-rival species coming to rely on these signals. But then, every once in a while, it gives a false alarm, to get the food-rivals to run away for a bit, so it can nab the bugs/berries/etc that the rival would have been eating.
