This family groups of two adult and three immature Tundra Swans was photographed by Curtis A. Marantz on 20 December 2016 as they flew overhead between the Salton Sea National Wildlife Refuge headquarters and Rock Hill, south end Salton Sea, Imperial County, California. I am not sure who initially found these birds today, but we saw this them afternoon after Guy McCaskie had called me to alert me that they were coming our way.
Деталі спостереження
After getting a call from Guy McCaskie noting that these birds were headed in our direction, we saw two adult and three immature swans as they flew in from the south and looping around to the north of us before dropping down to the northeast of our position; the adults were all white, the young birds clouded with gray on the uppersides of the wings and maybe also the heads and necks, but they seemed more extensively white than I would expect from young Trumpeter Swans. I saw what appeared to be black bills on at least the adults, but it was impossible to see fine details given our distance from birds that were seen exclusively in flight. These were conspicuously large birds with long, slim necks that were held outstretched, small heads, wedge-shaped bills, plump bodies, short tails, and moderately long wings that tapered to broadly pointed tips, and flying with relatively slow wing-beats.
