The time change - leave the dimly lit office and enter into the dimly lit evening.
Recent hikes - many caterpillars, many birds. Golden eagle, osprey, harriers. A male and female harrier took off from the hedgerow. I learned that harriers have a wobbly flight. Golden eagle was mobbed by the dozen crows. We got a good view - ID'ed it as a juvenile. Light-ish head and a strong white tail band. A flock of a dozen meadowlarks.
