Thursday Morning Walk at Las Gallinas
Location: Las Gallinas Storage Ponds
Trip Leader: Susan Kelly and Friends
Host: Vicky Van Meter, vicky.vanmeter@gmail.com, 415-299-2514
Start Date: Thursday, February 2, 2012
Start Time: 8:30 AM
End Time: 12:00 PM
Description: Beginner birders are especially welcome on the first Thursday of each month for a leisurely walk around the Las Gallinas Storage Ponds at McInnis Park. There is always something interesting to see and over 100 species have been reported over the course of a year. Winter is a busy time at the ponds and provides an opportunity to study ducks and geese. Hawks are frequent and we see the graceful Northern Harrier on virtually every trip. This is great way to start learning the raptors, waterfowl, and other groups, as well as getting tips on optics, birding books, and birding etiquette. Directions: From Highway 101 take the Smith Ranch Road exit; go east toward the McInnis Park entrance. Turn left immediately after crossing the railroad tracks and go the end of the road to the Las Gallinas Storage Ponds parking lot. Meet the group by the bridge just past the parking lot. The walk starts at 8:30 but late arrivals should easily be able to find the group.

The boat is very comfortable and the outer decks provide views over the levees of the amazing array of birds found in the Delta during the winter. This rich area hosts a wide variety of raptors including uncommon species such as Swainson's Hawk, Peregrine Falcon and Great Horned Owl. Large numbers of shorebirds, Sandhill Crane, Tundra Swan, Snow, Canada and White-fronted Geese, ducks, as well as gulls, terns, bitterns and passerines make the cruise a highlight for birders. We also will learn about the history, ecology and politics of the levees and the Delta as we travel through its meandering channels. The trip is limited to 25 participants and the cost is $95. This trip is full. Please contact Vicky Van Meter if you wish to be on the wait list.
