Subject: Re: [sbcobirding] More on shorebirds
I'll take a gander at your 3-inch, white egg. If it's 3 inches, then it's
larger than any duck egg. Based on what's likely to breed there or wash up
there, I think we have to consider Canada Goose as the best candidate.
It's eggs are said to be 3 3/8 inches, creamy white or dirty white,
unmarked, oval to long oval. Even though the breeding period of Canada
Goose is long over, an unbroken egg can last a long time.
Oddly, though the Breeding Bird Study shows 118 records of Canada Goose
breeding in SB County, none are from the Santa Maria River Estuary where
Jamie found this egg.
Play with *Breeding Bird Study* data viewed through *BirdView* for Canada
Goose or any species that breeds in the county here
