BOULDER COUNTY:

--A BLUE-HEADED VIREO was reported by Mlodinow at Golden Ponds, Longmont, near where the bridge crosses the creek/river, on September 10.

--Dowell reports a juvenile JAEGER at Boulder Reservoir on 9/16, an intermediate morph. The jaeger ID itself has morphed from Parasitic  to Pomarine, then closer views led to the ID of Long-tailed Jaeger (Nunes).  Jaeger ID is tough. So is empid ID, but at least empids don't sit on the water a half mile away.  Also Sabine's Gulls.  

COSTILLA COUNTY: Rawinski reported a trio of Sabine's Gulls at Smith Reservoir SWA, near Blanca, on September 14.

DENVER: Alec Hopping reported a Caspian Tern at Marston Reservoir, flying southeast toward Chatfield SP on September 14 and a Sabine's Gull at Marston on September 15.

EL PASO COUNTY:

--Peterson reports an ARCTIC TERN at Big Johnson Reservoir, on September 8,  in low light. Bill Maynard saw the bird today (9/9) and confirmed it as an ARCTIC TERN. The ARCTIC TERN was seen by Walbek and others from 11am til noon on September 9. B. Maynard reports seeing the ARCTIC TERN at Big Johnson on the opposite side of the reservoir where an island is seasonally located.  Scope for viewing desirable. The Lesser Black-backed Gull continues at Big Johnson Reservoir.

--Drummond reports a BLUE-HEADED VIREO at the Cassita, at Chico Basin Ranch, fee area, on September 13.

--A BAIRD'S SPARROW was found by Aaron Driscoll on Drennan Road on August 26. Many individuals have since reported up to 4 BAIRD’S SPARROWS near the intersection of Drennan and Hemingway (this area is southeast of Colorado Springs).  On Sept. 7, Mlodinow reports 3 ad. Baird’s Sparrows within 45 mins. before reaching the 90-degree bend in Drennan Road, there was 1 cooperative ad. Baird’s Sparrow on Drennan Rd. just east of that 90 degree bend. No subsequent news either way.

  

JEFFERSON COUNTY:

--A Ruby-throated Hummingbird was reported by Sanders on September 12, at this home. During the quick looks he had of the bird, he observed a red gorget, but it was a little different hue than the usual male Broad-tailed Hummingbird. Contact him via email (zroadr...@gmail.com) if you want to try to see the bird; visitors are welcome.

--A Black-and-White Warbler was reported on September 15 by Suddjian at the Mother Cabrini Shrine above Golden.

LARIMER COUNTY:

--A PARASITIC JAEGER was reported by Komar at Timnath Reservoir on September 13. The jaeger was not seen on the morning of September 14, nor on September 15, but is to be looked for on large lakes farther south.

-- On September 14, Komar reported several tern species at Boyd Lake, including FOUR ARCTIC TERNS. Helpful details are in Nick's post to CObirds at 10 last evening. Seen again by Komar on 9/15.  A first-cycle ARCTIC TERN was reported from there by Walbek on 9/16.

An adult LONG-TAILED JAEGER was found by Bankert on September 15 at Boyd Lake. Komar and others saw it that evening.
