Garth Riley led a very successful Bird Walk on September 16th. We usually get either nice weather or a good variety of birds. That day we got both! With approximately 200 species on our all-time bird walk list, adding new species is hard. Even our star bird of the day, a Yellow-crowned Night-Heron, had already been seen on a previous walk! This rare visitor from the southern US has been in the park for weeks but is often difficult to spot. With the trees fully in leaf and the birds in cryptic non-breeding or juvenile plumage, this is possibly the most difficult season to find and identify birds, but with many experienced observers in the group, we managed to find a good variety. As is typical for this time of year, we also found a good variety of migrating butterflies and dragonflies. By the end of the walk, we had tallied 44 species including 10 species of warbler - well above average for our September walk.
