Do you despise discerning among diving ducks? Feel bewitched by winter dowitchers? Want to groan about gull plumages? Care to spiff up those sparrow IDs? Come to Redwood Region Audubon Society's (RRAS's) annual potluck and bird ID workshop. Rob Fowler, RRAS field trip coordinator and owner of Fowlerope Birding Tours, will review confusing and difficult identifications often encountered during the Christmas Bird Count season. Bring a dish to share and a mug for shade grown coffee; RRAS will provide drinks, plates and utensils. The potluck starts at 6:30 p.m. and the program at 7:30 p.m. Please come fragrance free.
