Bird list update


Lots of new stuff. Yesterday, on my way to the first Biology Class with the Free Skool, I passed through Liberty Park, and got my first: Larus argentatus smithsonianus, the North American subspecies of Herring Gull (gråtrut).

Today, Andrew and I went to Antelope Island and Farminton Bay, but the fog was so thick that we could hardly see anything. There was some open water along the causeway that leads to Antelope Island, and we had some luck there with all three species of Bucephala in the world! A female Common Goldeneye Bucephala clangula, which is the same species as back home (knipa), but a different subspecies (B. c. americana), one pair of Barrow’s Goldeneye Bucephala islandica (islandsknipa), and several Buffelheads Bucephala albeola (buffelhuvud). There was also a Ruddy Duck Oxyura jamaicensis (amerikansk kopparand), lots of Chukars Alectoris chukar (berghöna), and some Canvasbacks Aythya valisineria.

We continued to Farmington Bay quite early, as we couldn’t see farther than about 100 m at Antelope Island. Farmington gave more Herring Gulls, as well as both Western Gull Larus occidentalis, Thayer’s Gull Larus thayeri, California Gull Larus californicus, and Ring-Billed Gull Larus delawarensis (ring-näbbad mås). Lots of Bald Eagles Haliaeetos leucocephalus (vithövdad havsörn) on the ice, and over-all a good diversity of birds of prey, including Hen Harrier Circus cyaneus (blå kärrhök), American Kestrel Falco sparverius (sparvfalk), and others. The most diversity was in ducks, however, with several large flocks containing:
– Mallard Anas platyrhynchos (gräsand)
– Pintail Anas acuta (stjärtand)
– Shoveler Anas clypeata (skedand)
– Green-winged Teal Anas carolinensis (amerikansk kricka)
– American Wigeon Anas americana (amerikansk bläsand)
– Gadwall Anas strepera (snatterand)
– Cinnamon Teal Anas cyanoptera (kanelårta)
– Merganser Mergus merganser (storskrake)
Some Pied-Billed Grebes Podilymbus podiceps (tjocknäbbad dopping) were in those flocks as well, and here and there on the ice stood Great Blue Herons Ardea herodias. One Song Sparrow Melospiza melodia (sångsparv) was foraging around the reeds where we were standing.

On the way out, we also saw a Red Fox Vulpes vulpes hunting in the snow!

We’re probably going back next weekend again when there’s no fog.

  1. Incidentally, the highest polytypic taxonomic unit that I have seen all taxa within is the order Gaviiformes (loons/lommar), with the last taxon (/Gavia arctica viridigularis/) seen a few hours after the second last (/Gavia pacifica/), both on my last day on Hokkaido in 2008. I *think* /Bucephala/ is the only other polytypic genus I have “completed”, but I’m not sure. There may be some two-taxon group I’ve seen all species in, but I can’t think of any at the moment.
