Return to Jackson Reservoir

Richard Stevens:

September 9, 2008

Gary Weston and I arrived at Jackson Reservoir, Morgan County about 5:00am. We heard an Eastern Screech-Owl for our first bird of the day (assisted with a playback
recording).

When it was light enough to see, we picked out the juvenile Long-tailed Jaeger that was found yesterday. Unfortunately before it was light enough for a good photo, it flew
off to the west (I did get a witness shot but it is pretty dark. Can tell it is a jaeger, but not good enough for ID). We did not see it the rest of the morning.

While walking the north woods (Jackson WLA) a Red-eyed Vireo was added to our day list. The best birds were found in the southwest corner. Here we had an American Redstart, Nashville Warbler and Cassin's Vireo. The campgrounds were slow and we walked the west side to the north end hoping to find a Long-eared Owl or Short-eared Owl. Neither was seen, but a Barn Owl came out of the woods east of the northern campgrounds. Two Great Horned Owls were also observed.

We debated on whether to head northeast to Prewitt Reservoir but did not add the extra miles to our bodies.

Late in the afternoon, I went alone to Cherry Creek Reservoir, Arapahoe County. A search of the Blackpoll Warbler and Magnolia Warbler reported by Loch Kilpatrick a few days earlier was not successful.

At the trees north of the Mountain Loop, a small flock of birds included 3 Black-capped Chickadees, 2 male Wilson's Warblers, and an Orange-crowned Warbler.

At the trees at the western tip of the Lake Loop I was counting Chipping Sparrows (added up to 47). While doing this, 5 Black-capped Chickadees appeared in the two young and short Russian Olive Trees. Always worth watching a flock of Chickadees to see what else might accompany them, I scoped them for 20 minutes. Sure enough a Townsend's Warbler was with them.

Scoping the southeastern sand spit was a bust. Three or four dozen American White Pelicans and 2 Killdeer were the only birds there at 6:00pm. My final stop was the southwest sandbar. Many pelicans, Double-crested Cormorants, Ring-billed Gulls, a few California Gulls, and Common Tern were here.

Rebecca Kosten and I heard that the Brown Pelican and Long-tailed Jaeger were no longer being reported in Boulder County. So we decided to drive east and checkout Jackson Reservoir, Morgan County.

On the way, we stopped at Crow Valley Campgrounds. Birding was slow but we did find a Brown Thrasher and a Cassin's Vireo. Several previous Mountain Plover locations were checked; without success. I then walked the road south from CR 96 (at 2.0 miles west of CR 77). Here I finally located a Mountain Plover. It was a juvenile bird.

Once at Jackson Reservoir, we hit the bonanza. A juvenile Long-tailed Jaeger was along the northeast shoreline. Mosquito numbers were tremendous………. We quickly scoped the corner and found a Semipalmated Plover among the mix. Further exploration was discouraged by the hordes of insects.

Owling Northern Colorado

September 6 & 7, 2008

Saturday
Mark and Eve Peters followed us up to Gould for two days. Target birds were owls. Our first stop was a good sign of success to come. We quickly found Flammulated Owls at two locations on Pennock Pass, Larimer County. An hour later I was able to find a calling Boreal Owl east of Cameron Pass!

Sunday
Earlier (4:00am) Mark and I drove up Ruby Jewell Road. This is one of my favorite spots in Jackson County. At 4:37 am, we were able to put a spotlight (briefly) on a Boreal Owl! After sunrise, we observed 3 Red-naped Sapsuckers, a Swainson's Thrush, numerous Pine Siskins, and Mountain Chickadees in the area.

Back at the Gould Store, we watched hummingbirds for 30 minutes. Most were Broad-tailed, with a few Rufous, and one immature male Calliope Hummingbird. While watching the hummingbirds, Mark picked out 2 Townsend's Warblers in the tall trees above the store.

A stop at the Colorado State Forest Visitor's Center was entertaining also. We heard and put a scope on an American Three-toed Woodpecker. Hummingbirds were quite numerous. A few Mountain Chickadees and Pine Siskin also visited feeders behind the building. Wilson's Warblers, a MacGillivray's Warbler, and a Fox Sparrow fluttered about the willows.

A flock of 6 Red Crossbills stopped briefly in the trees west of the building. A couple of Gray Jays looked for a handout. Swallows included Tree and Violet-green.

The Peters left for Denver and we stayed in Gould for another night. In the afternoon we drove down to the ghost town of Teller City. I always enjoy a visit here. There is a self guided tour of the old town that sprung up during the Colorado Silver boom. In past visits Northern Pygmy-Owls and American Three-toed Woodpeckers were observed. We did not see any today, but it was an enjoyable ending to our day.

By the way, the road down to the ghost town almost surely requires a 4WD unless you care nothing about your passenger car.

Rebecca Kosten and I stopped at Prewitt Reservoir, Logan/Washington Counties and enjoyed a fine afternoon of birding. Our interest was high enough for us to ignore the millions of mosquitoes. Could there have been billions?

Our day list included Ovenbird, Northern Waterthrush, Great Crested Flycatcher, Red-eyed Vireo, Cassin's Vireo, and Hooded Warbler. I played an owl tape to see if any sparrows would pop out of the tall grasses. Instead a nosy Eastern Screech-Owl called back. He must have wondered which of his buddies was making all the racket.

Besides the uncommon birds were saw White-crowned Sparrows, one White-throated Sparrow (below the dam), Western Wood-pewees, a couple of Empidonax Flycatchers, Spotted Towhees, a Green-tailed Towhee, Mountain and Black-capped Chickadees, Yellow-rumped Warblers, Downy Woodpeckers, and Western Meadowlarks.

Unfortunately, no unusual sparrows were among the Vesper, Brewer's, Lark, White-crowned, and Song Sparrows. We did see 2 Clay-colored Sparrows.

The hordes of mosquitoes discouraged us from setting up a scope and spanning the reservoir. There was a Common Tern flying back and forth. We did not want to stand still longer enough to get a good view of the lake.7
