SUMMARY:Fall Rarities: Searching For The Unexpected (Session 1)
DESCRIPTION:Instructor: Alex Henry \nFor Bay Area birders\, finding rarities in the fall is part of the fun. Our location on the edge of the Pacific Americas Flyway brings many species of birds through our area on their way south. Birds that normally migrate over the ocean get blown off course and land in the Bay Area\, while off-course birds that normally migrate over the North American continent may stop in the Bay Area to avoid going out over open ocean. In many species\, the adults begin migration before the juveniles\, so young birds may get lost and spend a few days here. By studying when and where these off-course migrants are seen\, and what weather patterns are associated with their arrival\, we can attempt to predict their occurrence and increase our chances of crossing paths with them. \nJoin Alameda County birder Alex Henry for a Zoom lecture presentation and field trip to sharpen your skills and hunt for fall rarities. \nTo maximize opportunities\, we’re offering two separate sessions of this class: This one in September and another one in October. Choose whichever class works best for you. (The material in each session is the same.) Field trip locations and directions will be announced in class. \nRecordings of the lecture presentations will be available to class participants  for a limited period of time. These two classes are the first of a series. We plan to offer similar winter\, spring and summer rarity classes. \n\nZoom lecture on Thursday September 16\, from 7:00 to 8:30 p.m.\nField trip on Sunday\, September 19. Time to be announced.\nLectures are via Zoom. Field trip locations will be announced in class.\nEach class is limited to 20 participants.\n$40 for GGAS members\, $60 for non-members.\n\nIf the class is full\, you may sign up to be on a waiting list. \n\n\n\n\n\nMDAS members pay the same rate as GGAS members! \nRegistration opens: July 1\, 2021 \n\n\n\n\n\n\nLimited to 20 participants

SUMMARY:Purple Martins In The Central Valley: Going\, Going\, Gone?
DESCRIPTION:Featuring Dan Airola\nThursday\, September 16 — 7 p.m. via Zoom \nMale Purple Martins in Sacramento\, by Lisa Alvarez\nPurple Martins have been in long-term decline in California due to factors such as habitat loss\, competition with the European Starling\, disturbance from construction projects\,  and declines in their insect food supply due to  neonicotinoid insecticide use. Dan Airola has been studying and working for over two decades to conserve the last Central Valley population of Purple Martins\, which nest in elevated freeways and overpasses in Sacramento.  This program will present his study results and describe conservation measures that have been implemented and are needed to protect this species and help it recover. \nAbout the Speaker \nDan Airola is a wildlife biologist and ornithologist who has worked for over 40 years on bird conservation issues in Northern California.  His recent research addresses status\, ecology\, migration\, and conservation of at-risk species including the Tricolored Blackbird\, Swainson’s Hawk\, Yellow-billed Magpie\, fire-adapted forest species\, and migrant songbirds.  Dan also serves the Central Valley Bird Club as a Director\, Conservation Chair\, and editor of the journal Central Valley Birds.
