Fortunately just before leaving home today for some errands a friend called with news that a Ross' Goose was begin seen up at Orange County's "Camel Farm" among 1,000 Snow Geese. Since I had not seen this bird since 2008, I was able to adjust my plans and got there within an hour. Pretty quickly I was able to locate the diminutive Goose amongst it's larger cousins. Also 3 Tundra Swans were on the pond too.
