Beaver Valley (1950)

Another of Walt Disney's True-Life Adventures features a glimpse of nature's own engineer hard at work in the wild. A young male beaver finds himself the head of his own family after successfully wooing a female and her kit, then quickly goes to work building a suitable home before winter arrives. Pressure mounts as a hungry coyote sets his sights on the young family, and a rollicking bevy of playful river otters threatens to derail construction. This 1950 Academy Award-winning short also includes the ill-fated journey of salmon returning to lay their eggs and a musical interlude featuring the soulful serenade of the lovelorn frogs.
