Big Break Trail, March 1, 2008

March 1, 2008
Wild Birds Unlimited Bird Walk
Big Break Trail, Oakley, CA
Leader: Chuck Groff

The day started overcast about 52 degrees with a cold wind
greeting us as we arrived. The sun came out later and
temperatures climbed to 63. The area has many habitats:
marsh, river, pond, and plowed fields. The treatment ponds
were full of gulls, almost all Bonapart's and a few
Ring-billed. At first we only saw the females of some birds
such as the Bufflehead, Common Goldeneye and Ruddy
Duck. But the males showed up and were appropriately
complimented on their attire. We never did see the male
Red-winged Blackbirds, adding a little mystery to the
identification process.
