TRAVELLING NATURALIST TRIP REPORT
20 March - 4 April 2005
Neil Arnold The Travelling Naturalist
Willy Alfaro Horizontes
Costa Rica is undoubtedly a fine holiday venue. In two weeks we travelled one thousand km and visited a wide range of habitats from mountains to the shores of two oceans. A huge variety of plant and animal species were noted. This was due to fine leadership from Willy and to the energy and enthusiasm of the group. I am grateful to the group for their good cheer, to Willy for his patient guidance and to Graivin and Jorge for their friendliness and expert driving. I hope we will meet again in the near future.
SUNDAY 20 MARCH
We flew to San Jose via Atlanta, USA. The trip went well and our passage through US immigration and customs was efficient and courteous, as was our entry into Costa Rica. We arrived at our hotel in the late evening.
MONDAY 21 MARCH
WEATHER 4-7/8 Cumulus, sunny, E breeze. Dull on the mountain.
We awoke to the splendours of the hotel garden. Birds abounded, including Hoffmans Woodpecker, Summer Tanager, Squirrel Cuckoo and Rose-breasted Grosbeak. We also enjoyed good views of the enchanting Variegated Squirrel.
After breakfast Jorge drove us to the Tapanti National Park. As it was the first day of the Easter holiday we made rapid progress through the streets of San Jose and were soon in the picturesque city of Cartago. On the outskirts we stopped briefly to scan the fresh water pools at Las Concavas. Here we found twenty Blue-winged Teal and a lone Northern Shoveler, the only records of the trip.
Within half an hour we entered the Orisi Valley, an area of coffee plantations dominated by rushing streams. Once at Tapanti, a huge tropical forest, we began to find a wide variety of bird species, including Green Thorntail, Coppery-headed Emerald, Red-headed Barbet and the very scarce Lineated Foliage-gleaner.
Lunch was taken at the Sendero la Oropendola, where the local trout was much appreciated. After lunch we made for Cartago and Route Two, the Pan-American Highway. This took us high into the mountains only to plunge down into the San Gerardo Valley at some 2,500 M a.s.l.
As soon as we turned off the main road we were in different world of lichen-covered trees clinging to steep slopes. Here we found the first high altitude birds of the trip: Sooty Robin, Long-tailed Silky Flycatchers, Flame-colored Tanagers, Large-footed Finch, Yellow-bellied Siskin, Volcano Hummingbird, Flame-throated Warbler and Mountain Elaenia. They were all lined up along the road as if they had known that we were coming!
Once settled into the Savegre Lodge we concentrated on the bird feeders. Grey-tailed Mountain Gem, Magnificent and Scintillant Hummingbirds competed with Green Violet-ear for the sugar solution.
TUESDAY 22 MARCH
WEATHER A.M. clear, sunny,still. PM heavy rain in the valley, mist at altitude
The morning was spent exploring the river, forest and open fields of the Gerardo valley. American Dipper, Torrent Tyrannulet and Black Phoebe were found on the river bank and a host of species in the forest. Black-throated Grosbeak, Collared Redstart and Yellow-thighed Finch were memorable. Whilst we watched a flock of migrant raptors flew overhead; one hundred and twenty Broad-winged Hawks were joined by at least twenty Swainsons Hawks and one or two Red-tailed Hawks. This was a spectacular example of visible migration, all these birds flying to North America.
After breakfast we explored a different part of the valley, finding four Sulphur-winged Parakeets at rest, a Red-legged Honeycreeper which was way beyond its usual geographical range, and a Ruddy Tree- runner, amongst many other species. Just before lunch we noted two Swallow-tailed Kites, a migrant from South America. The little Alfaros Squirrel also came to light.
In the afternoon it rained so we drove to the misty height of the Cerro de la Muerte. We drove along the rough track to the summit (at 3,500 M a.s.l.) where we found Volcano Junco, Black-billed Nightingale-thrush and a Timberline Wren. Our next port of call was Villa Mills, the abandoned road camp which was used when Route Two was built. Here amongst the flowering bushes we found yet more high altitude birds.
The only disappointing aspect of the day was that we had failed to see a Resplendent Quetzal, despite having spent some time watching two nests.
WEDNESDAY 23 MARCH
WEATHER AM clear and sunny. PM developing cloud, humid at sae level, a breeze
A pre-breakfast walk brought us into contact with a pair of sparkling Emerald Toucanets, a Black Guan and, at last, a Resplendent Quetzal. After we had been watching a nest for some while, a female Quetzal poked its head out of the nest hole, looked around and then flew to a nearby perch. As the bird was preening we were able to admire the fine plumage from many different angles. Eventually the bird returned to the nest and we went away with a sense of achievement.
The day was to be spent in a leisurely drive into the General Valley to Dominical on the Pacific coast and then along rough roads to Carara. Our first stop was at La Georgina, just below the summit of the Cerro de la Muerte. Here we spent a while watching hummingbirds at the local café. The star of this exercise was the stunning Fiery-throated Hummingbird. As we descended to San Isidro el General, lowland species began to dominate. We were soon enjoying views of parrots, herons, swallows, tanagers and toucans. Other notable species included a lone Laughing Falcon, Ospreys and six Swallow-tailed Kites.
We ate lunch at the estuary in Dominical. We were soon being entertained by Green, Little Blue and Tricolored Herons. Willets, a Greater Yellowlegs and Spotted Sandpipers soon reminded us that we were on a migration route. As Brown Pelicans and Magnificent Frigatebirds flew overhead our attention was drawn to the first Green Kingfisher of the trip.
As we moved north along a road surrounded by oil palm and banana plantations we kept discovering more birds. Both Ringed and Amazon Kingfishers were seen as we passed canals designed to drain the plantations. Perhaps the most enjoyable sighting of the trip was a Bare-throated Tiger-heron sitting by a roadside ditch. (Little did we know that we were to see many more individuals in the coming days.)
As we passed the estuary of the Seagre River we noted three Ringed, two Green and two Amazon Kingfishers. Roadside Hawks lived up to their name and were seen by the roadside as was a fine Ferruginous Pygmy Owl. As we approached Quepos a cheer rang out - we had reached tarmac road again.
As we reached the tourist town of Jaco, Willy took us on a mystery tour. It transpired that he had done some contract ecological surveys for the Marriot Hotel. On entering the grounds we soon directed our attention to the small lakes on the golf course. Least Grebes soon appeared. As we left the site we scanned the drainage channels finding a Roseate Spoonbill, White Ibis and a variety of herons.
We settled quickly into the spacious luxury of the Villa Lapas Hotel. Whilst eating our dinner we were surrounded by calling Pauraque.
THURSDAY 24 MARCH
WEATHER 0-4/8 Cu. Fine, breeze. PM torrential rain showers
An early morning walk around the grounds of the hotel was very productive. The first delight of the day was the fly-by of a pair of very noisy Scarlet Macaws. Then a variety of warblers, flycatchers, doves and thrushes came to light. The gardens also proved to be a haven for a variety of reptiles and amphibians including Green and Spiny-tailed Iguana, Basilisk, Yellowbelly Gecko, Cane Toad, Green Poison-arrow Frog, Tink Frog and Masked Treefrog. On the way to breakfast we also discovered a fascinating group of mammals, five Brown Tent-making Bats hiding in a tent made by biting the base of a leaf stem to make it droop.
By 08.00 we were entering the Carara National Park. Even before we passed through the gates we were watching a Plain Xenops, a very elusive forest bird. Then came a Blue-black Grosbeak, Slaty-tailed and Bairds Trogons, Red-and-white and Rufous-breasted Wrens and Rufous-tailed Jacamar. As if that was not enough splendour we then found both Orange-collared and Red-capped Manakins. As we watched a variety of hummingbirds a Tiny Hawk flashed along the path at barely more than head height. Then we had an opportunity to study a collection of ant birds. First Black-headed Antshrike made an appearance, closely followed by Dot-winged Antwren, Dusky Antbird, Barred Antshrike and Chestnut-backed Antbird. Then birds of prey caught our eye: Roadside Hawk, Plumbeous Kite and White-tailed Hawk.
Eventually we came to the small lake hidden in the forest. This stretch of water was dominated by herons, including roosting Boat-billed Herons. We also had close views of a Roseate Spoonbill, a small flock of Black-necked Stilts and a flock of Black-bellied Whistling-ducks. On our way back to the coach we came across a very lively troupe of White-faced Capuchin Monkeys and a lone Northern Royal Flycatcher.
After lunch we had a siesta well most of us did; some went out in the rain and found a Whiskered Puffbird, just reward for such endeavour.
We then intended to walk more forest trails but torrential rain caused a change of plan. We drove the short distance to the estuary of the Tarcoles River. As we arrived we were greeted by Yellow-naped Parrots. The muddy banks of the estuary held a variety of waders, Yellow-crowned Night-herons, Brown Pelicans and Ospreys.
By 17.00 we were on the Tarcoles road bridge watching American Crocodiles, an American Purple Gallinule and Red-winged Blackbirds. As it was the breeding time for Scarlet Macaws the evening flight to the National Park was somewhat disappointing: only two birds appeared. We had the consolation though that we had seen half a dozen birds in the forest during the day. As the light dimmed Lesser Nighthawks took to the air and we took to our heels; it was time for a rest and a well-earned meal.
That evening we said goodbye to our stand -in driver, Jorge and greeted our usual driver Greivin who is not only a good driver but a knowledgeable and spirited birdwatcher.
FRIDAY 25 MARCH
WEATHER 0-4/8 Cu, fine, breeze
The early morning walk produced sightings of Northern Barred Woodcreeper, Orange-billed Sparrow Blue-crowned Motmot and a small flock of Painted Buntings.
By 09.30 we were back at the Tarcoles Estuary watching wetland species including Semipalmated and Grey Plovers and Turnstone. We then made a brief stop at the Tarcoles Bridge.
By 10.30 we were en route for the province of Guanacaste. Within twenty minutes, though, we were parked by a small park in the little town of Ortina. We were then invited to have a look around the park. Within a minute we were staring up at a magnificent Black-and-white Owl perched in a tree. Having found such a prize we were then shown a Two-toed Sloth hanging upside down in the next tree. The photographers had a field day.
As we drove towards La Ensenada in the Refugio National de Vida Silvestre we were obviously entering a much drier habitat. The roadside kept giving up its wildlife. Mantled Howler Monkeys jeered at us from tall trees as we discovered Banded Wren, Turquoise-crowned Motmot, Northern Beardless Tyrannulet, Sulphur-breasted Flycatcher, Blue Grosbeak, Stripe-headed Sparrow and Streak-backed Oriole. We also had a brief glimpse of an Indigo Snake.
On our arrival at La Ensenada we went straight to the salt pans to take advantage of the fact that it was a holiday and therefore there was no disturbance. At the salt pans we found ten species of waders including Wilsons Plover and Short-billed Dowitchers. The area was also a haven for a number of species of herons and songbirds. At dusk we saw yet more Lesser Nighthawks. Twenty Mantled Howler Monkeys greeted us at the lodge as did a covey of Spot-bellied Bobwhite.
SATURDAY 26 MARCH
WEATHER 1-3/8 Ci, sunny, breeze
The lodge is surrounded by grassland, scattered scrub and trees. The coastline, two hundred metres away, consists of steep, low cliffs, at the base of which are mangroves growing on a gravel shore. Consequently the patchwork of habitats harboured many species of plants and animals. The most notable birds were Melodious Blackbird, Scrub Euphonia, Mangrove Warbler and a variety of wetland species including Neotropic Cormorant. Just before breakfast we came across Cinnamon Hummingbirds feeding in the flowerbeds, a pair of White-throated Magpie-jays stealing the butter and bread from the tables and a fine Pacific Screech-owl that Graivin had discovered in a nearby tree. (What it is to have a driver who knows the lie of the land!)
At 08.30 we left to drive to the River Bebedaro which abuts the Palo Verde National Park. Before we had even left the estate we found an elegant Double-striped Thick-knee standing motionless in the shade of a huge tree. As we made our way north we also noted seven soaring Wood Storks.
The boat trip on the River Bebedaro was very relaxing. We had fine views of Green and Spiny-tailed Iguana, the Jesus Christ Lizard (Basilisk) which runs across the water surface, White-faced Capuchin and Mantled Howler Monkeys, and two roosting groups of White lined Sac-winged Bats. Birds were represented by Bare-throated Tiger-heron, Solitary Sandpiper, Black-crowned Night-heron and Common Black Hawk..
After an excellent lunch we made for the Palo Verde National Park. As we approached the wetlands we were disappointed to find that they had dried up much earlier than usual; consequently we took to the open woodland. The dryness of the area can be summed up by the discovery of a flock of fifty White-collared Seedeaters feeding where there should have been wetland species. Just as we were about to leave a Scarlet Macaw flew over. This was exciting as it is a rare bird in the Park. We also had a brief view of a King Vulture in one of its strongholds. We were a little disappointed with the afternoon but we did not know what lay ahead.
As we drove through the forest we spotted a White-tailed Deer eating the fallen fruit of a mango tree. Nearby were others. The great surprise was to come next though. Near a young deer was a female Greater Curassow. Eventually we found seven females and five males. Thankfully they allowed us to leave the bus and quietly follow them through the forest. The discovery of this most elusive species raised our spirits.
We drove on to the wetlands. As we drew near the evening sun glinted on a pool of shallow water. The wetlands were wet! By standing on a bank we were able to see feeding White Ibis and Wood Storks. Then a flock of Black-bellied Whistling-duck took to the air. This action disturbed two white birds that had been hiding in the rushes. They immediately began to exercise their wings; we were watching two adult Jabiru, the most sought-after stork species in the neotropics.
As we drove through the forest towards the exit we were to get yet another surprise; a Thicket Tinamou, another elusive species, calmly walked across the road into the forest edge.
As it grew dark Graivin drove the bus along the irrigation dikes revealing a variety of wildlife. First we saw a Barn Owl and then several Common Pauraque. We then saw a series of mammals: a Grey Fox, Great Bulldog Bats fishing, and a Common Opossum. As we approached the main road home we saw another Barn Owl.
After yet another fine restaurant meal we wended our way home. It is hard to imagine a more varied day in the field.
SUNDAY 27 MARCH
WEATHER AM 4/8 Cu. bright ,still. PM 8/8 Cu. Dull, still. Heavy showers
The early morning walk revealed a number of significant bird species: the local Canivets Emerald, Spot-breasted Oriole and Panama Flycatcher.
By 08.00 we were on board a tractor and trailer ready to make a tour of the estate. It is surprising what can be found on a tractor ride. A Steely-vented Hummingbird was noted and two Lesser Nighthawks were found perched in a tree, then an Ivory-billed Woodcreeper came to light. Scrub Euphonia, White-tailed and Common Black Hawks were also noted.
After lunch we set off for the Arenal area. As we were passing spectacular yellow flowering Yellow Cortez trees we saw a perched Bay-winged Hawk.
Once past the town of Tilaran we were once again on the Caribbean slopes of the country. As we drove along the northern shores of Lake Arenal we stopped to look for wildlife. Northern Rough -winged Swallows were seen as were Cinnamon Becard and two Swallow-tailed Kites.
In the late afternoon we stopped at Toad Hall, an excellent gift shop, to buy presents. This was not our only motive, however: the garden was full of exotic birds. Sightings of Crested Guan and Grey-headed Chachalaca were soon followed by those of Black-cheeked and Smoky-brown Woodpeckers, Little Hermit, Green Honeycreeper, Black-cowled Oriole and Red-lored Parrots. We had to drag ourselves away!
While we were at Toad Hall there was a violent downpour. This meant that by the time we reached the Arenal Volcano, one of the most active in the world, we could see the whole cone apart from the rim, from which smoke could be seen pouring down the slopes.
Once at Volcano Lodge we walked to dinner. As we emerged from the restaurant later in the evening the sky was clear and moonlit and the outline of the cone could be seen in its entirety. This was a rare sight indeed.
MONDAY 28 MARCH
WEATHER 8/8/ Cu. Showers, dull, still
The gardens of the lodge were the focus of the early morning wildlife watching. Mealy Parrot, Green-breasted Mango, White-necked Jacobin and Lineated Woodpecker were the stars of the morning.
We set off for Selva Verde at 08.00 but we went in the wrong direction. This was one of Wills surprises. Within minutes we were overlooking a wet meadow. After a brief search we found two adult Southern Lapwing and two chicks. As this is a species that has only colonised Costa Rica in the past five years, this was a very important breeding record. Southern Lapwing isnt even pictured in the field guide!
By mid morning we had climbed to 2,000 M a.s.l. at Bajos del Toro Amarillo. Here in the middle elevation forest we were reacquainted with such species as Black Guan, Slate-throated Redstart and Yellow-thighed Finch. We also discovered Hairy Woodpecker, Yellow-bellied Elaenia and the very local White-throated Flycatcher and Golden-browed Chlorophonia.
By the time we had settled into the lodge at Selva Verde the light was fading but we managed to find a sparkling Sunbittern on the river bank, White-breasted Woodwren in the forest and the delightful Green Poison-arrow Frog and Strawberry Poison-dart Frog. This inspired us to expect great things on the following day.
TUESDAY 29 MARCH
WEATHER 5-8/8 Cu. Heavy showers, still
By 06.15 we entered the drive to the research station of the Organization for Tropical Studies at La Selva. For the next two and a half hours we walked the four hundred metres to the gate of the station. In that time we recorded seventy-five species of birds. Some of the most impressive species were Black-faced Grosbeak, Long-billed Gnatwren, Rufous-winged Woodpecker, Yellow-tailed Oriole and the scarce migrant Eastern Kingbird.
Once inside the research station we met Kenneth, our local guide. We were soon in the forest watching wrens, woodcreepers, thrushes and trogons. A Grey Catbird represented the migrants from North America, while Snowy Cotinga and a nesting Olive- backed Quail-dove were rare local species.
We were also lucky enough to see a herd of five White-collared Peccary; we also picked up their very strong scent. The reptile of the day was a spectacular Emerald Basilisk.
It had been a very special day in this essentially private enclave.
WEDNESDAY 30 MARCH
WEATHER 4/8 Ci. Sunny, breeze
The day started with sightings of a migrant Wood Thrush and a local Red-throated Ant-tanager.
By 06.20 we were back at La Selva. Things were different though from our experience of yesterday; due to Willys reputation within the organization he had managed to gain permission to walk the trails inside the station hours before groups were usually allowed to enter.
As a result of our early start we found three very scarce species of birds: White-collared Puffbird, Chestnut-coloured and Cinnamon Woodpeckers. High overhead we also saw White Hawk, Broad-winged hawk and a spectacular King Vulture. Further searching brought to light Golden-winged Warbler, Bay Wren, Broad-billed Motmot and Dusky-faced Tanager. A Coati and two huge mantids also attracted our attention, the latter being thoroughly photographed. Eventually we dragged ourselves away.
After lunch at La Quinta Lodge we returned to Selva Verde to rest. By 16.00 we were out on the trails again watching Sunbittern, Mealy Parrots, Collared Aracari and the most attractive Yellow-crowned Euphonia and Bronze-tailed Plumeleteer. On crossing the swinging bridge over the river we rigorously obeyed the command in Spanish: NO BALANCEARSE.
After dinner we drove to the La Quinta area in search of owls, but without success.
THURSDAY 31 MARCH
WEATHER 1/8 Cu. Sun breeze
We spent the day making the journey to Pachira Lodge, Tortuguero. We drove over metalled roads until we reached the outskirts of Siquirres. Here we took to unmade roads until we reached the tiny port of Caño Blanco. From here we were whisked away in a fast launch. The speed of progress didnt lend itself to wildlife watching but we did manage to see a male Red-breasted Blackbird as we passed an area of open grassland. Soon the river banks were cloaked in forest.
On our arrival at the lodge we discovered a singing Purple-throated Fruitcrow, a birds that usually lives deep in the forest.
By 15.00 we joined Giovanni, our boatman for our first trip into the Tortuguero National Park. We were soon on a forest trail. Almost immediately we came across a swarm of army ants. Army ants displace all in their path so they are often followed by antbirds which eat the fleeing invertebrates. A careful search of the undergrowth revealed Bi-colored Antbird, Chestnut-backed Antbird and Western Slaty Antshrike. Many other forest species were also noted.
The most unexpected mammal of the trip joined us at dinner: a Water Opossum dashed through the dining room at full pelt.
FRIDAY 1 APRIL
WEATHER 8/8/ Cu. Showers. Sunny afternoon. Stormy evening
This was a unique day, a day in which we enjoyed three boat trips: yet another new experience in my long leading career.
Our first trip started at 05.30, accompanied by a chorus of Mantled Howler Monkeys. The first really thrilling moment was the appearance of an American Pygmy Kingfisher which was photographed at point blank range. Then we were shown a Great Potoo hiding on a huge tree. We then glimpsed a Neotropical River Otter.
At 10.15 we were off again. The highlights of our trip to Caño Harold were a Great Black Hawk, a White Hawk, Double-toothed Kite, two sightings of the scarce Green-and-rufous Kingfisher and two Green Ibis. Perhaps the most exciting moments were supplied by several sightings of Sungrebe, prolonged views of a Neotropical River Otter, Spider Monkeys and Mantled Howler Monkeys. From my own point of view, though, the discovery of three species of herons was the pivotal point of the trip. First we found a fine Bare-throated Tiger-heron, and then a Rufescent Tiger-heron, but the real prize was an Agami Heron in full breeding plumage; all were close. We held our breath as we watched.
At 15.00 we boarded the boat again. We made for the Caño Palma and the Rio Suerte. Herons were common, as were kingfishers. At one point we came across a huge American Crocodile surrounded by Black Vultures. Smaller Spectacled Cayman were also noted. We also saw a mature Sungrebe standing on a log showing off its pale lobed feet. White-faced Capuchin also performed for us. As we returned to the Quay a Bat Falcon flew overhead. It had been a remarkable day.
SATURDAY 2 APRIL
WEATHER 4-7/8 Cu. Fine, breeze
After an entertaining morning walk we sped to Caño Blanco in a launch.
By 10.30 we were driving through open grassland. Red-winged Blackbirds, a Short-tailed Hawk and an Olive-crowned Yellowthroat joined our collection of birds. We also had a brief view of a Bird-eating Snake. After lunch at Guapiles we drove through the Braulio Carrillo National Park. We stopped at an abandoned butterfly farm 800 M a.s.l. We watched the fine display of flowers, eventually discovering Blue-throated Goldentail, Black-crested Coquette and Snowcap.
Once at the Bougainvillea Hotel some of us searched the garden for birds, discovering the very attractive White-eared Ground-sparrow, and then the very scarce Prevosts Ground-sparrow. What a finish to the trip!
SUNDAY 3 APRIL
WEATHER 3/8 Cu. Sunny, breeze
An early morning walk in the garden was wonderful. We noted White-eared Ground-sparrow, a glimpse of Prevosts Ground-sparrow and six Crimson-fronted Parakeet.
After breakfast we set off for home via San Jose, Atlanta and Gatwick. The trip home was very smooth, especially through immigration and customs at all points.
I hope you have all enjoyed this trip as much as I have..
