... and suddenly I'm thinking of the kingfisher. At some point during my teens my parents bought and set up an above-ground swimming pool in our back yard, near the fence dividing the yard from cattle pasture. There was a small flowering thorn tree growing on the fenceline, and nearly every non-winter day for several years a kingfisher would spend a couple of hours of each morning perched in it, watching the pool intently in case fish magically appeared; the rest of the day was, presumably, spent down the hill by the river where the fish were real.
We really should have dumped a couple of goldfish in one day, just as a reward for all that patience ... ;p
