The scouts
A 47-minute ornithology doc about migration patterns and pesticide policy sounds like the most conventional Earth Day programming imaginable—which is exactly why I'm surprised Caruso makes it feel like a genuine expedition film, tracking not just hawks but the anxiety of witnessing something irreplaceable slip away.
Caruso situates this work squarely in the lineage of committed nature documentary—the patient observation, the satellite technology as elegant narrative device—while the film's formal restraint (letting the 11,000-kilometre journey speak for itself) recalls the best of NFB's environmental essay tradition.
The decision to follow the hawks via tracking data rather than just field footage creates this haunting abstraction—you're watching a journey you can't see, which somehow makes the threat more visceral than any on-screen dying bird ever could.
