Wednesday morning at Heather Farm Park in Walnut Creek
I had limited time this morning to ride my bike around, it was pretty quiet, anyway. The best bird by far was a Wood Duck on the edge of the concrete pond near the private Seven Hills School. I found Ted Robertson on his bike and told him about it. His eBird list is here: https://ebird.org/checklist/S72581758
Wood Ducks are seen on this pond or the large, mostly natural pond just a handful of times each year.
