WS of trees in woods, pulls back, music plays. Cut to shot of bushes, bunny hops out from in them. Cut to shot of branches of evergreens, music continues to play. Cut to WS of field, trees in foreground and background. Cut to shot of trees and nature. Cut to CU of bird in tree on tree branch. Narrator begins to talk about nature. Cut to shot of tops of trees, sun in background. Cut to shot of small pond, ducks in it, tree branch hanging over it. Cut to pan overlooking trees, panning over river. Shot of birds on field. Cut to shot of hand switching eggs in a nest. Cut to shot of bird approaching eggs. Mother bird instinctively covers eggs. Shot of her flying off. Cut to shot of her attempting to hatch wooden eggs and wooden blocks. Cut to shot of hand switching eggs back. Cut to shot of bird on nest. Cut to shot of ripple in water, cut to long shot of water and trees. Screen goes black, words come up that narrator reads. “Study, compare, add up the facts... without them your theories are efforts made in vain.”
