  • Thanks to the CBRC for all their good work. I was a little disturbed to see Yellow-green Vireo removed from the review list, considering the findings of this major multilocus vireo phylogeny: http://cjbattey.com/papers/slager2014MPE.pdf Basically, East Mexican Yellow-greens are poorly differentiated from North American Red-eyeds, while west slope/southern birds are a different...

  • Hello Isaac, I would call it the more expected Anna's Hummingbird. It lacks rufous in the tail and on the sides, has a grayish chest, and you can see a few diagnostic red feathers coming in on the crown. Best, Tristan McKee Arcata, CA On Mon, Jan 5, 2015 at 8:40 PM, sanchez@^$1 [CALBIRDS] < CALBIRDS-noreply@^$2 > wrote: I need help with the ID on this hummer. These photos were...

  • Folks, As I presume there will be many excellent birders in Arcata this week, I'd like to ask for help with relocating and photographing a potentially very interesting gull. Some experts are reconsidering the ID of last August's Eureka bird as a Lesser Black-backed, and on Saturday, I saw a structurally very similar LBBG-like bird in Arcata with yellowish-green legs, an almost...

  • Hi Floyd and all, It's a very cool duck. I was at a loss as to how eliminate a Canvasback x Redhead hybrid, so I started picking apart some photos, then reading a little natural history. The first thing that struck me was that the border between the bill and face is very straight and angles back and down toward the chin. Perhaps it is an artifact of the photo, but the only duck I...

  • It finally dawned on me that all the issues with the mystery warbler at the Laguna Road tamarisks in Camarillo being a Mourning might be resolved in one simple package: 1) It is assumed to be "dull", because of the whitish on the sides and belly, yet the throat and center of breast are a rich, almost orangey yellow. 2) The aforementioned whitish on the underparts. 3) It was cocking...

  • Folks, We have not relocated the sandpiper, despite intensive efforts all over the Arcata Bottoms and Marsh. Not being a big fan of single-observer first state records (although I was once a strong advocate of putting Three-toed Woodpecker on the list!), I won't be pushing this as the first record south of Alaska. I am especially concerned with the prevalence of hybridization in...

  • Just before dusk this evening, I had good views of a persistently-calling Green Sandpiper at Klopp Lake, which is at the south end of I Street in Arcata. A series of very unique "kleep" calls drew my attention to the bird as it circled the lake. I had many good views of the striking dorsal surface in flight, which showed a white band across the lower rump/tail base, contrasting...

  • The Elk River gull has not turned up this morning, although gull numbers are lower and it was present all day yesterday (gulls are out foraging now). Current consensus is tending toward a very large male Lesser Black-backed Gull. Barring two unreviewed records of Heuglin's-type gulls, this would be Humboldt's first record (although it could be a taxonomically-questionable Asian...

  • Today (2 Aug 2014) a number of Humboldt birders have been studying a striking 1st/2nd cycle gull at the Elk River Mouth, Eureka (off Hillficker Drive). It appears to be a very strong Kelp Gull candidate. The overall appearance is reminiscent of a Lesser Black-backed Gull, but the bird is about the size of a Western, has broad wings, a largely dark tail, and boldly checkered wing...

  • Hi Calbirders, Regardless of its identification, the juvenile gull frequenting downtown Arcata this winter provides an unparalleled opportunity to ponder Slaty-backed characters up close, in direct comparison with Glaucous-winged and Herring gulls and their apparent hybrids. These hybrids are the source of the popular notion that first-cycle Slaty-backed Gulls simply cannot be...
