WESTERN USA 2009 This is a trip report from a family holiday in Western USA. We travelled from San Francisco (July 17) to Seattle (Aug 14). The weather was less stable than we had expected. On most days we had good weather with long daylight hours and temperatures 90-105 °F in the southern part of the trip (CA) and cooler in the northern parts (WA). The week before our holiday started, I visited the symposium of the International Society on Thrombosis and Haemostasis at Boston (MA). During this week I went twice on a whale watching trip from Boston harbour to Stellwagen Bank. In our holiday we visited Monterey (CA), where we took a whale watching trip, Aňo Nuevo State Reserve (CA), Pinnacles National Monument (CA), Kern River Preserve (CA), Giant Forest Sequoia National Park (CA), Kings Canyon National Park (CA), Lassen National Park (CA), Freezeout Lake (MO), the Rocky Mountain Front (several walks near Choteau (MO)), Glacier National Park (MO) and Tongue Point (Olympic Peninsula (WA)). This trip included expected and unexpected highlights. Birds ranged from Black-footed Albatross to Californian Condor, eleven species of Wood Warblers, Harlequin Duck, White-headed Woodpecker, four species of Loon including an immature Yellow- billed Loon, Northern Pygmy Owl, Boreal Chickadee, Pine Grosbeak, Ruffed Grouse, Blue Grouse, a stunning male (‘Franklin’s’) Spruce Grouse, to Tufted Puffins. Mammals were abundant. We had great views of Black Bear and Grizzly Bear, fighting males Northern Elephant Seal, whistling Pika’s, Moose, Snowshoe Hare, a Humpback Whale, three species of Dolpin and Sea Otter. Our timing was perfect to observe the wild flowers of the Rocky Mountain Front and Glacier NP. Landscapes and scenery ranged from the Pacific Coast to high alpine scenery (approx. 3,000 m). We travelled approximately 4,700 miles. Literature Field guide to the mammals. Burt, W. H. and Grossenheider, R. P. (1978). Peterson Field Guide Series. Houghton Mifflin Company (ISBN 0-395-24084-0).

Itinerary July 12 During the ISTH meeting in Boston MA, I joined an afternoon trip with Boston Harbour

Cruises to Stellwagen Bank (14.30-18.45). The weather was beautiful but windy. Great views of Humpback and Fin Whale, Wilson’s Storm-Petrel, Cory’s Shearwater and Greater Shearwater.

July 15 I joined a second tour to Stellwagen Bank (10.00-13.30). Only a single Fin Whale was seen,

but at least 20 breaching and bubble feeding Humpback Whales. Bird migration had started, several small flock of Dowitchers and “peeps”.

July 17 A flight from Boston to San Francisco (American Airlines). Car (full size wagon) rented from

Alamo. Annelien, Wessel and Imie arrived two hours later. Drive to Half Moon Bay (Holiday Inn).

July 18 We rose at 04.00. Left at 08.00, drove to Aňo Nuevo State Reserve en walked to North Point.

At least 150 males Northern Elephant Seal (4,500-5,000 lbs) were seen. Especially their gurgling sounds have to be heard! Also Harbour Seal, Californian Sea Lion, a Sea Otter, Pacific Bottlenose Dolphin and Mule Deer were seen. I dipped on two snakes seen by Imie. Most apparent birds were Song Sparrow, White-crowned Sparrow and Osprey. Overnight stay at the Cypress Garden Inn (Monterey).

July 19 From 09.00 to 13.20 a whale watching tour with Montery Bay Whale Watch. Visibility was

cumbersome during the first part of the trip. Many Risso’s Dolphin and a single Humpback Whale. Birds included Black-footed Albatross, a possible South-polar Skua, Sooty-, Pink-footed and a single Black-vented Shearwater. The sea was not too flat, and Imie and Annelien were sick. Afternoon swim in the pool of the Cypress Garden Inn. Brief stroll along a rather nice trail immediately opposite our motel.

July 20 Awoke at 05.00, prebreakfast tour with Annelien, a.o. Mule Deer and a nice male Wilson’s

Warbler. Bought groceries at the Safeway and visited (10.00-1300) the famous Monterey Aquarium, which is a reconstructed factory –part of the famous Canary Row. Sea-otters could be seen inside as well outside (wild!). Drive via Hwy 1 to Big Sur, where we walked a short trail. Rather foggy during the morning, afternoon blue skies. Picture below: Pinnacles National Monument, July 21.

July 21 Left 08.30 for Pinnacles National Monument (West side). Drive via G16, a scenic drive but

time consuming road due to the many curves. Arrived at Pinnacles about 11.30, where it was rather warm (99 °F) with a hot wind. We walked the Balconies Trail, which included two “caves”. Despite the heat we saw several good birds, including four distant Californian Condor, Oak Titmouse, Rock Wren, Canyon Wren and a small flock of Wrentit. Imie obtained her first Junior Ranger Badge of the trip. Drive via Soledad and Caolinga to Hwy 5 South, and then to Wasco via 46. Several other birds included Yellow-billed Magpie, Western Meadowlark and Phainopepla. Overnight stay at a Best Western Motel.

July 22 A slow drive, via Bakerfield, along Lake Isabella behind some trucks. Walked from 09.00-

12.00 a trail at the Kern River Valley Preserve. Despite the heat (100+ °F) there were many birds around, including Californian Quails, Black-headed Grosbeaks, a male Scarlet Tanager, Yellow Warbler, Nashville Warbler, Lazuli Bunting, Raven, Oak Titmouse etc. In the afternoon we drove, via Kernville and Fairview, to Giant Sequoia National Monument (Southern Unit), walked the wheelchair accessible Trail of 100 Giants (14.00-16.00). Truly stunning Giant Sequoia’s and Ponderosa Pines. Birds included our first White-headed Woodpecker, Western Bluebird, Yellow-rumped Warbler, etc. Drive to the next Best Western (Exeter).

July 23 Left early for Giant Forest Sequoia National Park. We bought a map at the ranger station and

drove to Crescent Meadow. We walked to Eagle View and returned via Log Meadow. Near Low Meadow we met the first Black Bear of the trip. This bear was so close that we could hear its sniffing. After lunch, we walked to the General Sherman Tree. This tree has the largest estimated volume of 1470 m3 of any tree in the world. The forest was surprisingly rich in mammals and birds: Least and Golden-mantled Squirrels, Chickaree, Yellowbellied Marmot, seven White-headed Woodpecker, House Wren, Western Bluebird, Yellow-rumped and MacGillivray’s Warbler, Raven, Western Tanager, Townsend’s Solitaire, Pacific Slope Flycatcher, Hairy and Acorn Woodpecker. At the end of the afternoon we drove back to Exeter for another night at the Best Western (still 100+ °F). After the pasta, we enjoyed the swimming pool.

July 24 We tried to book another night at the motel, but had to move to the Kaweah Motel. Left

early for Giant Sequoia NP, where we walked from Wolverton to Pear Lake (elevation 2800 m). The weather was great with a crystal clear blue sky. We met our second cinnamon coloured Black Bear, an immature, that was trying to find some food. The birds were

relatively quiet, but we had good views of Rufous and Calliope Hummingbirds, and again White-headed Woodpecker. Returned to Exeter at 18.30, had cold pasta and a swim.

July 25 After breakfast (cold pasta and crackers), we left again early to drive to King’s Canyon NP via

the 245 North. This road was a straight line on our not too detailed map but proved to have a horrendous number of curves. Although the distance was about 50 miles, it took us about 1.5 hours of tough driving! We walked to Sugar Bowl Grove (10.00-14.30). The weather was beautiful with clear blue skies, the trees were truly giant and the birds were relatively plentiful, including a nice male Black-throated Gray Warbler, Hermit Warbler, Bushtit, Red-tailed Hawk, etc. Since this was a Saturday and King’s Canyon NP is a busy park in summer, we decided to leaf and drive to Los Baňos (Best Western).

July 26 Left at 08.00 and briefly visited the San Luis Refuge Complex, just North of Los Baňos, which

is a famous reserve for wintering birds. Although the timing could have been better, we saw a lot of birds in about 1.5 hours: our only Cattle Egrets of the tour, Great and Snowy Egret, Nuttall’s Woodpecker, Bullocks Oriole, American Goldfinch, etc. For the first time this holiday both Imie and Wessel practiced their driving skills. Drive (99 N) to Chico. Just before Chico we saw at least 100+ White-faced Ibis and our first Swainson’s hawk. Temperature still 100+ °F. Brief views while driving of the only Tricoloured Blackbird of the trip.

July 27 We started early and drove to Lassen National Park. Unexpectedly, a gasoline station was out

of order and we had to return 40 miles to obtain gasoline. As a consequence, we arrived at the visitor centre at noon! Brief drive to the Crag Campground, pitched up our tent and bought meat for a BBQ (another 18 miles single drive). Afternoon walk along scenic Manzanita Lake (16.00-17.30), were we saw Red-breasted Sapsucker, Olive-sided Flycatcher, Hermit- and Orange-crowned Warbler, Buffleheads (common), Pied-billed Grebe. We enjoyed our first BBQ and camping.

July 28 Walked to Lassen Peak (elevation 3200 m; 07.15-11.45). Beautiful walk with great views. Birds were relatively scarce. Had lunch at King’s Creek (elevation 2200 m; 12.00-14.30), where a little trail along the river proved to be quite productive: a female Evening Grosbeak, Red Crossbill, Pine Siskin, Dipper, etc. We returned early (16.00) to the campground, since a thunderstorm was expected. The campground produced a Red-naped Sapsucker and a White-headed Woodpecker.

July 29 Walked to King’s Creek Falls (07.30-11.30). Good views of Williamson’s Sapsucker, Dipper, a

female (sitting) Calliope Hummingbird, a male and imatures Evening Grosbeak. We enjoyed our lunch again at King’s Creek, and then walked to Bumppass Hell. We had brief views of the mud pools and geysers due to rain and hail showers. Beautiful views of Mountain Bluebirds. We saw (and heard) two rescue helicopters, since two people had become wounded when walking to Lassen Peak. Drive to Shingleton for meat and other groceries.

July 30 Left Crag Campground and started 09.30 with the walk to Cinder Cone. Due to the heat,

especially the trail to the cone proved to be tough; the Cone itself was steep but not too high. The volcanic scenery was scenic, but birdlife was cumbersome. Returned around noon, had a quick lunch and started driving to Lakeview (ORE). Some birds during a brief stop at Modoc National Forest. We enjoyed another overnight stay at a Best Western Motel (Lakeview). Temperature still over 100 °F.

July 31 A travel day. We left 07.30 and arrived about 16.00 (17.00 Mountain Time) at Riggens (IDA).

Passed Lake Albert (395 N), which was crowded with migrating waders and gulls. The whole area is volcanic and due to the sage brush it is very scenic but not much of a tourist trap. During a stop we saw Black-necked Stilt, American Avocet, Franklin’s Gull and our first Pronghorns. For Burns we saw Sandhill Cranes and two Coyotes, of which unfortunately one was shot by a farmer before our eyes. Drove the 20 E to Ontario and then 95 N to Wiggens. Several good birds while driving, including Swainson’s Hawk, Ferruginous Hawk and Common Nighthawk. We slept again in a Best Western Motel. Temperature still over 100 °F.

Aug 1 Again a travel day. Drive –via Grangeville- along the 12 to Missoula. We saw several female

Common Merganser and Mule Deer. Then drove to Freezeout Lake near Choteau. Despite that the water level was high, we saw Wilson’s Phalarope, Baird’s Sandpiper, Greater Yellowleg, several species of Grebes and Ducks (16.00-17.30). Due to the heat (90+ °F) we again decided to search for a motel. We booked two nights at the Stage Stop Inn. The only room available was a room for a disabled person with “only” a double bed. We enjoyed the swimming pool and home-made lentil soup (including a Polish sausage).

Aug 2 Annelien and I visited Freezeout Lake, starting at the poorly indicated entrance road between mile markers 34 and 35. Saw several Short-eared Owl and waders. Returned to the motel at 10.00 and visited the Rock Shop at Bynum. Lunch at the Eureka Reservoir, then drove to Ear Mountain and we walked the first 1.5 miles of the trail to the top. Great views of a Prairie Falcon. Returned to Choteau at 17.00, enjoyed all a single scoop of local ice cream and decided to skip dinner. At about 18.30 tried to find the dirt road to Egg Mountain. Although we did not find the road, we drove the 89 South and then a little dirt road that started at mile marker 59. While the children again practiced their driving skills, we had our finest hour by having great views of Pronghorn, Coyote, White-tailed Prairiedog, a flying and then perched adult Ferruginous Hawk, Swainson’s and Red-tailed Hawk, Northern Harrier, a female Merlin, Horned Lark, and McCown’s and Chestnut-collared Longspur. Returned to the motel at 20.30 and we all had a good swim.

Aug 3 Bought groceries and gasoline in Choteau. Drove to the end of the South Fork Road, and

walked 7 miles (return) to Our Lake (also called Hidden Lake). This area is part of the Rocky Mountain Front and very scenic. Beautiful walk with many flowers. At the parking lot saw a Spotted Sandpiper foraging in the river and a male Townsville Warbler. Drive to Choteau via minor dirt roads.

Aug 4 Our final day in Choteau. Drove to the end of the South Fork Road, and started walking to

Headquarters Pass at 10.00. We saw again many flowers, including several species or Orchids, Golden Eagle, and Pika. We had crippling views of Boreal Chickadee. The weather was still beautiful. We did some shopping in Choteau, had an early dinner (noodles) and Annelien and I went for a post-dinner tour to “Egg Mountain” (287 S, immediately right at the radio transmission tower). We were less successful than the previous evening, but still saw Pronghorns and Northern Harriers. The sky started to change and we expected bad weather.

Aug 5 A weird day. The weather forecast was cumbersome, but we decided to drive to St. Mary in

Glacier National Park. While travelling to Glacier NP there was fog and rain, but once we were in Glacier the weather improved. We pitched up our tent and walked the Iceberg Lake Trail (13.30-19.00). The trail was extremely productive despite other tourists, and we managed to see a female / juvenile Ruffed Grouse, a male and three chickens of Blue Grouse, several Golden Eagles, a Moose and six Mountain Goats. While returning to our car, a ranger told that they were expecting really poor weather for the coming days, including lots of rain. We decided to break down the tent while Imie and Wessel were delivering Imie’s Junior Ranger Programme at the Visitor Centre. Then drove back to Choteau where we arrived about 22.30. The Stage Stop Inn was full and we stayed overnight at the Montana Big Sky Motel. A great name for a ramshackle but cosy motel.

Aug 6 We slept very well. Annelien and I went shopping at Rex’s Supermarket and bought warm

pizzas and coffee at the gasoline station. We all enjoyed the pizza breakfast. We re-visited the Rock Shop and drove to Logan Pass via St. Mary. We walked the board walk, saw Gray-crowned Rosy Finch, from about 13.30 – 15.00, but then a thunderstorm started. We drove via Lake McDonald and Hungry Horse to Kalispell, where we found a room (Motel 6) at 19.00. The instable weather made our planning difficult.

7

Page 8: Western USA 2006 - Earrebarre USA (West).pdf · • Field guide to the mammals. Burt, W. H. and Grossenheider, R. P. (1978). Peterson Field Guide Series. Houghton Mifflin Company

Aug 7 Left at 07.00 and arrived at Logan Pass at 09.00. Walked part of the trail and had good views

of a male Townsville Warbler, American Pipit, Swainson’s Thrush, etc. Returned and decided to walk the trail to Grinnell Glacier. Due to some difficulties in finding the starting point of the trail, we ended up by (telescope) views of a foraging Grizzly Bear at Many Glacier. We started the trail to Grinnell Glacier at 14.30, and enjoyed truly stunning views of a close and very tame male Spruce Grouse (Franklin’s form), brief views of a female Pine Grosbeak, Hammond’s Flycatcher and a Goshawk. Despite the predicted (very) poor weather, the weather remained fine. Camped at the St. Mary’s campground.

Aug 8 I rose at 05.00 and enjoyed two pre-breakfast walks (campground - visitor centre): Osprey,

Bald Eagle, White Pelican, Calliope Hummingbird, Willow Flycatcher, a mixed flock of Wood Warblers including two unexpected male American Redstarts, Yellow and Orange-crowned Warbler, an unexpected Catbird, Cassin’s Vireo, Belted Kingfisher, Cedar Waxwing, juveniles Red-naped Sapsucker, etc. Wessel and Imie awoke at 09.00 and we drove to Many Glacier to enjoy a well earned ice-cream (Ben and Jerry). When entering Glacier National Park, an immature Black Bear crossed the road. Walked the Ptarmigan Lake Trail, which was less spectacular than the walk to Grinnell Glacier. Together, we walked a total distance of about 25 km. A bit windy, but otherwise beautiful weather.

Aug 9 Again a brief pre-breakfast walk. Birds included Cooper’s Hawk, Merlin, Osprey and Bald

Eagle. While driving to Logan Pass, we had close views of an adult Black Bear eating berries. Walked the Highline Trail (12 miles), starting at Logan Pass at 10.00 am. At the start it was foggy, but later on the sight improved. We saw Bighorn Sheep, a single Pika (but heard many more), and Columbian Ground Squirrel was common. Birds were tame, but a distant calling Northern Pygmy Owl and a fly-by Pine Grosbeak were true highlights! Returned to Logan Pass by the shuttle bus and arrived in Kalispell (Motel 6) at 20.30. Bought several pizza’s.

Aug 10 Another travel day (550 miles). From Kalispell along Flathead Lake, Polson, and Hwy 90 to

Tacoma (Motel 6). Briefly visited the Ninepipe Wildlife Reserve, which is part of the National Bison Range, where we saw Trumpeter Swan and a male Wood Duck. We had nice weather, but before Seattle / Tacoma it started raining.

Aug 11 Pouring with rain. After breakfast we decided to drive to Port Angeles. This proved to be a

good strategy, since the weather greatly improved near Tongue Point. Birds were plentiful, including several species of Auks, Common Loon, an immature Yellow-billed Loon (a rarity) and Bald Eagle. Visited the outdoor shop at Port Angeles. While preparing diner with fine views of Juan de Fuca, a close and tame Red-breasted Sapsucker further improved the scenery.

Aug 12 Again an early start (05.30). Pre-breakfast tour with Annelien at the campground produced a

Racoon, Red-necked Grebe and stunning views of a perched adult Bald Eagle. During breakfast I saw three Harbour Porpoise. The weather was nice. Drive to La Push. There were several ‘mixed bird flocks’, including (50-100+) Tufted Puffin, Brown Pelican, several species of gull, Common Murre, Pigeon Guillemot, Clark’s Grebe and Black Scoter, Red-throated Loon, Common Loon and Pacific Loon. We collected firewood and drove to Ediz Hook (Port Angeles), where we saw Harbour Seal and our fist Cassin’s Auklet.

Aug 13 Annelien cleaned the tent. Drive -via Port Angeles (Safeway, outdoor shop and hardware

store) to Dungeness Wildlife Refuge, a sandy peninsula. We walked a part of the trail towards the lighthouse. Lots of gulls, Harbour Seal, a single Parasitic Jaeger, close views of Least and Western Peep, Royal Tern. The weather remained surprisingly good. Drive to Tacoma where we almost dipped on a motel room due to a local dog show.

Aug 14 Apart from reshuffling some of our luggage (one or two bags proved to be too heavy), we

had a good return journey.
