Re: Tundra or Trumpeter Swan at Batiquitos Lagoon Again
To me, and a few others, this bird appears to be a TRUMPETER Swan. Unfortunately, given the presence of a pair of pet Trumpeter Swans at Lake San Marcos (just 5 miles east of Batiquitos, where there are also Black Swans, etc. on display), and an apparently successful breeding attempt by that pair in 2016 that produced 5 young, one could (should?) surmise that this one, and the one seen a few months ago are of that ilk and not of truly natural origin. This of course muddies the situation for any future reports of Trumpeter Swan anywhere in the county, and also increases the need for good photographs of Tundra Swans that do occur occasionally in the county in *winter* (12 November – 18 March, per the atlas).
San Clemente Island, where no swans, black or white, have been reported
