This composite is being put together from a series of three shots of a same sequence of multiple shots starting from top to bottom. Crows are known for aggressively harrassing other raptors that are much bigger in size when spotted in their territories and usually these ‘intruders’ simply retreat without much fuss.
However, in this frame the crow did not seem to harrass the bald eagle at such close proximity and neither did the bald eagle seem to mind the crow’s presence invading its personal space. What made it even more bizzare was that the crow even made a brief stop on the back of the eagle as if it was taking a free scenic ride and the eagle simply obliged.
I was once told that this is how some hummingbirds from Costa Rica made their way to the United States by riding on the back of the migrating geese and I simply gave a ‘yeah right..’ nodding as not to offend the person who came out with such theory. After witnessing this behavior, he may actually have solved the mystery.. :)
