In September 2004, PWA began a weekly bird survey of birds seen from the Shollenberger Park trail. The goal was to establish which species were present, in what numbers, and in which seasons. As long as the observation took place from the trail system, every bird seen was recorded, whether in the park, flying overhead, or even outside the park. Since the beginning of the annual surveys, the data collected have been sent to PRBO Conservation Science. Beginning with the second annual monthly survey, the data were also posted on the California eBird Web site at eBird.org (a real-time online bird observation checklist developed by a partnering of Audubon California, PRBO Conservation Science, and Cornell Lab of Ornithology).

Data will be used to help evaluate the quality of the habitat at Shollenberger Park, as well as provide information on the stability of our migratory bird populations.

Team bird survey leaders are Peter Colasanti, Lisa Hug, Andy LaCasse, Peter Leveque, Richard Merriss, Ruth Rudesill, Robert Speckels, Ron Storey, and Ken Wilson. Len Nelson coordinated the effort and compiled the statistics thru December 2009, and an Excel document of these observations can be obtained by emailing Len at lennelsn@comcast.net . Surveys beginning January 2010 were coordinated and compiled by Mary Edith Moore and the Excel document can be obtained by emailing her at maryedithmoore@comcast.net
