Everything

 Scientists don’t know everything

Cardinals don’t always pair off, but stay in families year after year

Woodpeckers don’t just eat bugs off trees, but lots to hang on the side of feeders, choosing the best the sparrows have to offer

Dogs are faithful, even when abandoned, even until death

Cats create self-sufficient communities, packs roaming individually in spring and fall, sharing knowledge of food sources, killing moles and leaving them, eating mice and robins, showing other cats the way, warning strangers and waiting for them to prove themselves worthy

Landscapes change yearly, strong trees die unexpectedly without reason, water creates its own paths even though paths have been made for it through much study, rocks move, trees are stronger than rock, rock is stronger than dirt, water trumps all

Nothing replaces daily observation
