What is lost in this frantic chase is the important fact that warblers are relentlessly active. These tiny drips of yellow are in the midst of a transnational journey and are eating bugs, fruits, flies, and nectar at a voracious rate. Warblers flit through the canopy, bounce from limb to limb and turn over leaves in the understory looking for food. They are in constant movement and movement it turns out is easy to see when standing stationary using quiet eyes.
To achieve quiet eyes or splatter vision simply let the eyes go soft and unfocused and suddenly the tree canopy, an infinitely complicated interlace of leafy crowns is flattened and the eye no longer studies each branch and leaf but instead skims the scene looking for quivers and shakes. The whole landscape turns to a bowl of mint jelly, wind can be seen as waving sheets moving through the branches, bugs and airplanes flying near and far become related as tiny black specs moving in either a smooth or frenetic direction, and the bounce of warblers in branches stands out.
Using quiet eyes is not natural and takes practice. We are trained to constantly focus and refocus on the near than far. We need to read faces, read street signs, read books, and the tiny keys on our phone, rarely do we relax our eyes and let the world pour in at once and perhaps we should.
