I'm pretty sure that this the "Nature" documentary that they showed a week or two ago on PBS. From Jeff's comments about the "lazy" male, I'm actually quite sure that it's the same video (with the straying female wolf?).
I loved the footage, but was also annoyed by the nararration. They spoke of the nest failing the previous year and I'd love to know if the "observation" of the pair that year was overzealous and perhaps contributed to the failure. But who knows.
Still really cool footage of the gyrs taking the hares.
Thanks for posting it here Fred.
