Mt. Diablo Audubon field trip report


Annually, around this date, MDAS traditionally incorporates in its repertoire of field trips, areas near to, and including, the Martinez Regional Shoreline Preserve.  Today, 1/29, a respectable number of us continued this tradition, beginning at Waterbird Regional Preserve, overlooking the north end of McNabney Marsh.
Birds identified from this location include:

Our next destination was the pond in Martinez, along N.Court St, part of the Martinez Shoreline Park. Birds identified from this location include:

Next stop, the observation platform, west side of McNabney Marsh.A great viewing position, generally speaking, but not particularly productive, today.Obviously, looked for the previously reported Eurasian Teal...not found. Also lookedfor the Lesser Yellow-legs...not found. Also on the lookout for luck.Not even a Sora...weird.
We did scope, from quite a distance, a male Kestrel,  perched atop an old Kestrel house at the western end of the  McNabney Preserve.  
The day concluded with lunch and a walk through sections of the renovated Moorhen Marsh, a wetland maintained by the Mt. View Sanitary District.This site was closed for two years during the extensive work, and re-opened to the public last May. The restoration project is ongoing, including removal of much non-native vegetation, and planting of several riparian species. And the birds are returning.

Bird numbers and variety will most certainly improve as the riparian growth begins to mature.
All in all, a very pleasant and productive day of birding with a total of 72 species sighted.
Good birding to all,Tracy Farrington,Walnut Creek
