The wolf-birds

the long version

"In a story set deep in the wild winter wood, two hungry ravens fly in search of their next meal. A pack of wolves is on the hunt, too. Food is scarce, but, if they team up, the ravens and wolves just might be able to help each other. The ravens follow a pack of starving wolves on the hunt. The wolves come up empty handed and even lose one of their own in the chase but the ravens have better luck. The wolves hear the ravens cawing and investigate only to find an injured deer, the perfect meal! The wolves make the kill; the opportunistic ravens benefit, feasting alongside and after the wolves."--Provided by publisher.
