ITINERARY.

All the following photographs were taken by myself, except for the Mountain Plover & the Gunnison Sage Grouse.

12th April 2001. Arrived Denver Airport after a night’s delay in Chicago after Denver Airport was closed due to 20 inches of snow. We met up with Dick Filby who had arranged this trip together with several other observers. We stayed with Dick for around a week, and Doreen and myself decided to stay on for an extra week so we could cover some of the same sites to obtain further views of the birds and also allowed us time to visit several other sites.

We first stopped off  at the prairie dog grassland off Tower Road near Denver Airport. We then drove south to Springfield some 5 hours drive, stopping en-route at Nee Noshe Reservoirs. and overnight at Springfield Motel.

14th April 2001 Early morning visit to the Campo Lesser Prairie Chicken Lek. We then drove to Bonny State Park before driving onto Yuma with an evening visit to the nearby Greater Prairie Chicken Lek some 14 miles south of Yuma. Overnight Harvest Motel, Yuma.

15th April 2001 Early morning visit to the Yuma Greater Prairie Chicken Lek and then general birding around Yuma. Drove out to the Pawnee National Grasslands and spent the rest of the day driving and birding on the grasslands and overnight at Fort Collins Holiday Inn.

16th April, 2001 Mountain drive from Fort Collins on route 14 West stopping many times birding including a visit to the National Park near Gould. Drove onto Walden (10,300 ft), with an evening visit to Greater Sage Grouse Lek at Coal Mont. To find this lek, go south-east from Walden on Highway 14 and from the junction of 14 at Walden you drive for 14.3 miles. You then turn right onto a dirt road opposite a sign with Evans Ranch on it. You travel along the dirt track until you come to a smaller dirt track on the right with a small pointer saying Sage Grouse and you follow this track until you arrive at the lookout. From the Highway 14 to the lookout is 1.6 miles. From the lookout you look straight along the track and the lek is either side of the track. If you stay in your vehicle, odd birds will come down to the parking lot and display right next to the car. Overnight North Park Motel in Walden.

18 April 2001 Drove to Hayden in the dark, for early morning visit to the Sharp Tailed Grouse Lek. To find these leks coming from Steamboat Springs on Route 40 to Hayden turn right just before the Coneco Garage on the right hand side in Hayden. On the side of this small road is a green sign - National Forest Access, California Park Road. The road splits and you take the right hand dirt road. The dirt road splits again by some farm buildings and a obvious large grey metal barn on the right and you take the left hand dirt road. From the Coneco Garage you travel 5.4 miles and you will come to a Cattle Grid with a small parking like area on the right. This is where we saw the Blue Grouse displaying both on the road, the parking like area and open field just over the cattle grid. A further 1.2 miles and the Sharp Tailed Grouse lek is on the left just the other side of the fence, which runs along along the road. It is not obvious and is best to drive a little way past the lek, turn the car around and come back, you can then look onto the small hill and the bird's lek on this side of the hill. There is a further lek on the same side of the road back towards Hayden over the cattle grid and between this cattle grid and the Blue Grouse site. It is again situated on a small hill and although the hill is close to the road the birds can only be seen from some distance looking fairly close to the cattle grid. We then drove back through the Yampa River Valley to Steamboat Springs. Afternoon visited Steamboat National Forest to Columbine. Overnight Rabbit Ears Motel, Steamboat Springs.


Local wild flowers.

19th April 2001 Drove to Grand Junction via Route 131 and I70 birding in juniper forest en-route and the Grizzly Creek Rest Area. Checked out both the Evening Grosbeak and Western Screech Owl stakeouts at Grand Junction and then drove through the Black Canyon birding on route to Gunnison.
Evening visit to the Gunnison Sage Grouse Lek at Waunita. Overnight Water Wheel Inn Motel, Gunnison. 
This leck can be found by travelling East on Highway 50 from Gunnison. If you drive from the Best Western Motel situated on the East side of Gunnison on Highway 50 for 16.6 miles you will come to a dirt road on the left hand side opposite the small green road mileage post 176 and a sign pointing to Waituna Hot Springs. Take the dirt road on the left for 0.6 mile and park by the lookout (with hay bales). Look out to the right and the lek is the other side of the fence about half way out towards the hill. They are easily spooked and both times we saw the grouse, they left the lek and flew virtually over the cars and into the sage on the opposite side of the road.


Grizzly Creek Canyon Rest area.

20th April 2001 Early morning visit to the Gunnison Sage Grouse Lek at Waunita. We then drove to Monarch Pass and onto George Town. In the afternoon we visited Guanella Pass and walked up to 11,830 feet (fresh fall of snow). Overnight George Town Motel.

Ross’s Goose – Chen rossii
At least 20 were identified in the flock of Snow Geese present in the fields near Nee Noshe Reservoir on the 12th. Fairly difficult to pick out at a distance but distinctive when closer when the small size, very small bill, small rounded head lacking the slope on the forehead and very short necked.

Barrow’s Goldeneye – Bucephala islandica
One drake and 2 duck were seen on Walden Reservoir on the 17th.  It was interesting to compare the duck Barrow’s with the duck Common Goldeneye.  The bill was noticeably smaller on the Barrows and with far more yellow making the bill quite bright compared with Common. The head had a different profile with a steep forehead. The bill for me was by far the best identification feature.  The drake was a stunning adult and all were seen well with the scopes.

Recorded on four dates with a maximum of 20 on the 26th on Walden Reservoir.

Common Merganser (Goosander) – Mergus merganser

Red-Tailed Hawk – Buteo jamaicensis                                                                 
Recorded in fair numbers on 16 dates with a maximum of ten on a day but many Hawks were not identified from the moving car and therefore the maximum probably far exceeded this. A number of different colour phases were seen including one dark phase Harlan’s Red-Tailed Hawk in the Black Canyon near Estes Park. This individual was first identified as a Ferruginous Hawk as it had a very pale tail and lots of white on the underwing primaries but the upperwing was completely dark.  It was seen on the 28th.

Ferruginous Hawk – Buteo regalis
Eight individuals seen on four dates with 5 on the Comanche Grasslands on the 13th. An impressive Hawk generally with a pale tail and pale head and white patches on the upperwing primaries.

Twenty-one of these Grouse were seen on their lek displaying during the early morning of the 18th near Hayden although the views were somewhat distant. A visit to another lek near Hayden on the 25th produced much nearer views of 18 birds right next to the road and we watched these for over an hour. I was able to photograph these.

Lesser Prairie-Chicken – Tympanuchus pallidicinctus
A very early morning visit to the lek at Campo on the Comanche Grasslands on the 13th produced superb views of 10 males in full display. A further visit to this lek on the 14th again produced excellent views of 7 males displaying and I was able to photograph them.










Lesser Prairie Chickens at lek at Campo, on the Comanche Grasslands. Sadly the Lesser Prairie-Chicken is in decline and is now listed under the Endangered Species Act.

Greater Prairie-Chicken – Tympanuchus cupido
An evening visit to on the 14th to a lek near Yuma produced 12 birds displaying and an early morning visit to this lek the following morning produced 20 birds.  The main lek was some distance from the track but views through the telescope of 3 birds much nearer displaying was very enjoyable but only record photographs could be obtained.




Greater Prairie Chicken near Yuma.

Gunnison Sage-Grouse – Centrocercus minimus
An evening visit to a lek near Gunnison on the 19th was negative so we were somewhat relieved to find 22 of this recently split species displaying during the very early morning on the 20th. After half an hour a Rough-Legged Buzzard flew in and landed on a post on the lek and this spooked all the Grouse, which flew off into the sage.  A further visit was therefore made on the early morning of the 24th and this time 33 birds were displaying for much longer putting on a fine display but immediately the sun came above the hill, all the birds flew off the lek almost passing over the car.

Greater Sage-Grouse – Centrocercus urophasianus
An evening visit to a lek near Walden on the 16th produced amazing views of 56 birds displaying.  One of the males as it was getting dark approached us to with 4 yards and displayed at us for 15 minutes, quite amazing. Early the following morning we had 80 birds at the lek of which up to 10 were displaying in the car parking lot and again stunning views were had. On the 18th 7 were seen displaying at a lek near Hayden and 2 were seen at this lek later in the morning on the 25th.  Further visits were made to the Walden lek on the 25th when 55 were counted and on the 26th when 60 were seen and again exceptional views obtained.  One of the main highlights of the trip.

After much searching, two in full breeding plumage were found on the Comanche National Grasslands and gave excellent views. One of the birds was sat on a scrape and appeared to be incubating. A further 7 were seen on the 15th on the Pawnee Grasslands but the views were no where near as good due to the pollution haze, which was present on these grasslands, and the distance we were from the birds.
