Red-tailed hawks soar in the Bitterroot Valley
I am amazed how often film producers display wildlife, especially birds in one of their movies and improperly add the call of a bird other than the one pictured.
One classic that comes to mind is Dances with Wolves. The scene shows Sandhill cranes migrating but the sound you hear is Canada geese honking away! Probably the most common misrepresentation is found in westerns where a Bald eagle, raven, or Turkey vulture is pictured with the call of a Red-tailed hawk sounding out loudly. TV producers should consult with a wildlife biologist prior to final edits, as they often go to such troubles to ensure authenticity only to have their wildlife sounds mismatched with the species they are highlighting.
