Détails de l'observation
First observation at 0652. 1 counted on property. First sighting was of an individual that flew upstream and landed near the diversion in reach 3. At 1144 observed the fourth GBHE of the survey: all of these sightings were of single herons flying upstream. Ca 1450, saw 1 GBHE flying more or less downstream over the E part of reach 4 at ca 4x shrub height, then circling lazily with flaps. Apparently found a thermal and rose to 10-15x shrub height, at which point I stopped observing it. Detections (number 15-minute intervals in which the species was detected): 1 on property. 4 flyover(s).
