August continued the trend of poor reporting begun in July with the result that only 122 bird species were recorded. The most exciting sightings were a Yellow-crowned Night Heron, an Upland Sandpiper and a Pacific Wren. This is only the fourth report of Yellow-crowned Night Heron since the wildlife inventory started in 1979. Upland Sandpipers were considered equally unusual until their flight calls began to be used as a means of identification three years ago. We now know that there is a steady trickle of these birds flying overhead at night that was previously unknown. Pacific Wren was recently split from Winter Wren, and we are still learning about the occurrence of these two species in the county. TOP
