    Endemic to the "sky islands" of Southeastern Arizona and adjacent Mexico and New Mexico, this attractive perennial herb is a member of the Verbena family.

    Red Phalarope

    Often called "Grey Phalarope" in Europe, the plain gray mantle, heavier bill and plumper body help distinguish this non-breeding (basic plumage) Red Phalarope from the similar Red-necked Phalarope. Red Phalaropes breed in the High Arctic and winter in the open ocean. Much of their migration...

    Long-tailed Duck

    Formerly known as the "Oldsquaw," they are scarce winter visitors to California from Arctic breeding grounds. They have declined significantly on their wintering grounds since the early 1990's and are listed as "vulnerable" by IUCN. Unique among waterfowl they are the only member of the genus...

    Native to the western United States where it favors mountain meadows. This composite is sometimes called Orange Sneezeweed because the pollen often causes an allergic reaction. This perennial is also said to be toxic to livestock, especially sheep. Formerly included in the genus "Dugaldia."

    Note the dark spots on the margin of the hindwing. These blues seldom showed the dorsal side of their wings, but the underside is well marked with wavy brown and white stripes. This species is widespread in North America particularly in the West but also ranges south into Central America. Two...
  19. Satyr Comma (Polygonia satyrus)

    Satyr Comma (Polygonia satyrus)

    This is a type of anglewing butterfly. The genus "Polygonia" means many angles. On the rear underwing you can see a white "comma" which gives this butterfly its name. Their caterpillars specialize in stinging nettle. The adults seldom feed from flowers but more often drink from moist ground as...
  20. Mixed Tiger Moth (Lophocampa mixta)

    Mixed Tiger Moth (Lophocampa mixta)

    We were alerted to this interesting caterpillar by a small child. This species apparently has no English name so I made one up based on its Latin name. Adults are yellow with red trim and mixed red wing markings. This caterpillar has four distinct black spines, two near the head and two near...
  21. Red-necked Grebe

    Red-necked Grebe

    The striped face indicates juvenile plumage. Note the yellowish bill with extensive dark tip. Juveniles such as this often have a reddish chestnut neck recalling breeding plumage as seen here. Unlike most other grebes, this species has dark brown, not red eyes. They are a scarce winter visitor...
  22. Glaucous Gull

    Glaucous Gull

    This rare but regular winter visitor to California is an immature showing the distinct pink-based bill with contrasting black tip. It can be difficult to age immature Glaucous Gulls due to variation in molt and appearance. The dark eye and worn pointed primaries indicate that this is a HY...
  23. Cattle Egret

    Cattle Egret

    Presumably one of the same two birds seen 10 December at nearby Cypress Lawn Cemetery. This one is in non-breeding (basic) plumage lacking the cinnamon-buff plumes of breeding plumage. The broad rounded primary tips suggest it is an adult. Now uncommon in Northern California after former range...
  24. Black-headed Grosbeak

    Black-headed Grosbeak

    It takes two years before adult males get their full orange and black plumage. Often heard singing loudly from within the canopy of tall trees, they can be frustratingly difficult to see. This male represents the nominate Rocky Mountain race, in which the male lacks the orange stripes on the...
