Notes on Sites

La Mechita: a few roadside shacks between San Ignacio and Piso Firme, surrounded by partially logged forest. This is where people travelling by bus from Santa Cruz need to disembark and await pick-up by the park vehicle from La Florida. There are cheap rooms for rent here if you have plenty of time and want to bird the area for a morning or two

La Florida: about one and a half hour's drive from La Mechita, this is a small village on the banks of the Río Paragua near which the administrative buildings for the southern sector of Parque Nacional Noel Kempff Mercado (PNNKM) are situated. There are cheap rustic lodgings in the village for travellers and it is possible to spend a couple of days in the area birding along the river and nearby roads. This is certainly a cheaper alternative to Los Fierros and most species will be shared between the sites. Los Fierros (and beyond) is of course much better for mammals as the people of La Florida are avid hunters. If you are visiting Los Fierros, El Encanto, Huanchaca II etc., it is necessary to pick up a guide from La Florida who you must feed throughout and pay 10 dollars daily. The guides are pretty good, although know little about birds and speak no English. We can recommend Juan (older and genteel, with a hunter's knowledge of animals) and Leon (younger and fitter), both very helpful.

Los Fierros: This is the main base for visitors to the southern sector of the park. Several rooms with showers go for between 20 and 40 dollars a night. Because of this price many people camp, or at least try to until they realise the severity of the insect problem (various ants and termites are a nuisance to tents, mosquitoes and bees are quite common seasonally). Management here is a bit slack and campers are regularly allowed into some of the more shabby rooms for free. If travelling independently, you need to bring all your food; there is a well equipped if slightly grubby kitchen.

At Los Fierros there are only limited options: the road that returns to La Florida, the road to the pampa, and two short trails. The best of these is a loop that begins directly opposite the wecome-to-Los Fierros sign, over on the other side of the airstrip (we call this the airstrip trail). Another leads to the right c.700 m along the road to the pampa. This road leads through 3 km of forest before reaching the pampa, and is good for birds along its length. After 10 km of pampa, the road forks into two. The right-hand fork leads to El Encanto, the left to La Laja.

El Encanto: The impressive waterfall called El Encanto lies c.45 km drom Los Fierros, but the track ceases to be driveable c.5 km before the falls. At this point there is a stream with drinkable water and two open sided "cabañas", one for tents and another designed for cooking over wood fires: ideal for camping. The forest between this camp and the waterfall is mostly quite degraded (the camp was established for loggers), and becomes increasingly deciduous towards the base of the meseta. Back towards Los Fierros there is continuous semi-evergreen forest of varying quality: the first 2-3 kilimetres are again quite degraded, but after this there are some bands of high quality forest. The patchier forest was excellent for watching canopy flocks, and whole area seemed very rich in mammals. A total of seven hours night-walking or driving produced three tapirs, a great long-nosed armadillo and a margay, while daytimes produced sightings of both puma and jaguar.

La Laja: After the road forks left on the Los Fierros pampa, it first travels through high quality tall cerrado with scattered trees 2-3 kms, then it runs through a couple of bands of Heliconia-dominated semi-deciduous woodland, before the vegetation becomes taller and more humid. The road terminates after passing through c.4 kms of high quality evergreen forest, and a narrow path continues to the base of the meseta. Forest along this path is relatively degraded, becoming more deciduous as the slopes of the meseta are reached (a distance of c.4 km). A short way uphill there is an official campsite called La Laja (which means The Slab of Stone, an apt description of the place). There are no facilities here except for clean running water year-round in a small stream, and a flat space for tents. The term La Laja as used in text below refers to the c.10 km wide band of forest from the Heliconia-dominated habitat adjoining the Los Fierros pampa, to the deciduous forest around the La Laja campsite, and including the band of drier cerrado on slopes immediately above this campsite. I've subsequently learnt that the stretch of road and trail below La Laja is sometimes known as Los Españoles.

Huanchaca II: Continuing up from the La Laja campsite, the walls of the meseta can be scaled in less than an hour. From the summit, it is another c.2 hour walk across open campo (short grassland) to the forest fragment called Huanchaca II. Here, at the edge of forest, by a clearwater stream, there is a camp consisting of rustic tables and poles for running tarpaulin over, with flat ground beneath to camp on. There is also a covered area for fires and store-boxes. One trail leads to the "piscina," across a variety of high quality campo habitats, and another trail runs through the woodland. In text below, the term Huanchaca II refers to any location between the edge of the meseta and the forest fragment itself.

Piso Firme: This village stands on the banks of the lower Río Paragua and is reached by taking a narrow dirt track from La Florida. This track runs through the sticks. It holds its course for seven hours between two walls of trees with only one turn-off and a wooden shack called Pension Picaflor to break the monotony. If you haven't brought a 4-wheel drive vehicle from Santa Cruz or San Ignacio, it is possible to make this journey by renting out a park vehicle at Los Fierros/La Florida, or catching the once-weekly bus that runs through La Mechita north to Piso Firme, or hitch-hiking on a passing truck. The guards at Los Fierros can help work out your passage north.

Piso Firme itself is a tranquil place full of fishermen and washerwomen, with clean rooms for rent by the river (US$3/person/night for luxury version with showers; cheaper for the local version) and a PNNKM guard-station. It is a classic Amazonian village with the advantages of electricity and a rustic restaurant that will cook you delicious fresh river-fish any way you want it. It is possible to hire a boat for the c.5-hour journey to Flor de Oro (c.US$200, thus only viable for groups). Alternatively, Flor de Oro could be reached by waiting for the park supply boat to leave (much cheaper, but infrequent), or to wait for other river traffic heading that way (also infrequent, but lots of fun). There are trails in forest nearby if required, and boats or canoes can be rented for river exploration around Piso Firme. Ask at the restaurant or guard-station.

Flor de Oro: A luxury camp mostly visited by tour-groups. Rooms are US$40-80. It is possible to pick up your own food from the nearby town of Pimenteiras in Brazil, cook for yourself and camp, but this takes a bit of persuasion. Camino Norte (or the Swamp Loop) runs through a patch of seasonally flooded forest, and back through bushy cerrado. Camino Sur runs through riverine habitats and then enters a strip of reasonably tall forest adjacent to a bahia (oxbow lake). The third and final option is the trail that starts across the airstrip and runs through seasonally flooded cerrado to another small forest fragment (Isla de la Orquidea). The Bellavista and Paucerna guardposts are downriver on the Río Iténez, towards Piso Firme.

Lago Caiman (sometimes - e.g. on Sjoerd Mayer's CD-ROM - known as Andrew's Camp): During the wet season (usually Dec-March) or the early part of the dry season (April-August) this camp is fairly easy to reach by boat, being half an hour upstream of Flor de Oro to the lake entrance and then 15 minutes along the lake itself. During our visit, at the end of a long dry season, we needed to carry the boats across a 50 m desiccated section separating the lake from the main river, and then navigate through stretches of clogged water-hyacinth, making the journey 2 hours long and quite exhausting. Once at the camp there is a trail that returns to Flor de Oro (something like 12 km through forest, then 12 km through pampa, an 8-hour walk). There is also a trail that goes to the Mirador de los Monos, although this trail had fallen into disuse before our visit and was impassable (they open it at tour-group's request). There was once a house inhabited by researchers at Lago Caiman, but this has fallen down, and the camp is mostly defunct. The other way of reaching the Lago Caiman forests is to take the tractor from Flor de Oro across 12 km of pampa, and then walk towards Lago Caiman; this is the option taken by several tours lately. Immediately downstream of the point at which Lago Caiman debouches into the Río Iténez there is a short trail or two through seasonally flooded forest with open understorey. This looked a dead-ringer for Rusty-necked Piculet and we found it there with little trouble.

Highlights

Best of the birds were Grey-bellied Hawk, Lined Forest-falcon of the soon-to-be-split southern form, Dark-winged Trumpeter, Red-throated Piping-guan, Crimson-bellied Parakeet, Cinnamon-throated Hermit, Horned Sungem, Spotted Puffbird, Black-girdled Barbet, Red-necked Aracari, Gould's Toucanet, Rusty-necked Piculet, Uniform Woodcreeper, Dot-backed Antbird, Chapada Flycatcher, Helmeted Manakin, Flame-crested Manakin, Snow-capped Manakin, Tooth-billed Wren, Black-and-tawny Seedeater and Rose-breasted Chat.

Mammals were especially good with four sightings of Jaguar, one of Puma, one of Margay, one of Jaguarundi, three sightings of Tapir, one of Great long-nosed Armadillo, several encounters with tame groups of Giant Otters, and great views of both Pampas Deer and pink river dolphins (Botu).

Species Lists

The following inventories include all species (452 birds and 43 mammals) recorded within or very close to park boundaries. Time in the field was heavily weghted towards tall forest with relatively little time being spent in open/cerrado habitats (only two early mornings during the whole visit). For mammals, nomenclature and systematics follows Emmons and Feer (1997), while the bird list is based (with amendations) on the original Conservation International RAP list for the park (Bates et al. 1996).

WESTERN WOOLLY OPOSSUM Caluromys lanatus
3-4 seen (and photographed in mid-stratum) while night torching at El Encanto in tall semi-evergreen forest

COMMON GREY FOUR-EYED OPOSSUM Philander opossum
Two together c.300 m from Los Fierros lodge in vine-tangled mid-stratum of partially logged forest, 8 pm

COMMON OPOSSUM Didelphis marsupialis
3-4 seen around El Encanto camp at night in undergrowth and ground of disturbed forest

PYGMY SHORT-TAILED OPOSSUM Monodelphis kunsi
One seen at Flor de Oro on a path through regrowth dividing riparian woodland from cerrado grassland; this individual disappeared slowly down a small burrow when approached

MOUSE OPOSSUM sp. probably Marmosops dorothea
One individual watched scuttling through vines at head height near the El Encanto camp

SOUTHERN TAMANDUA Tamandua tetradactyla
One set of tracks seen on Camino Sur, Flor de Oro; others were seen at Los Fierros along the airstrip trail during our stay

GIANT ANTEATER Mymecophaga tridactyla
Claw marks, some very recent, seen in termite mounds near Huanchaca II. Our guide reported that out of 30-40 journeys to Huanchaca II he had twice seen this species in daylight from the trail through grassland

SILVERY MARMOSET Callithrix argentata [recent taxo changes?]
Often heard at Los Fierros and El Encanto, where about six groups were seen; heard twice at Lago Caiman (T)

[FELINE NIGHT MONKEY Aotus infulatus]
Calls of Aotus were occasionally heard in humid forests; one group of 3-5 seen over camp at Lago Caiman (8 pm) were probably this species, but possibly Azara's Night Monkey A. azarae

BROWN CAPUCHIN MONKEY Cebus apella

Fairly common (1-3 troops seen or heard most days) at all sites visited (T)

RED HOWLER MONKEY Alouatta seniculus
A pair (male and female) seen along Camino Sur, Flor de Oro

BLACK HOWLER MONKEY Alouatta caraya
Heard daily at Huanchaca II, with a family group seen once (T)

WHITE-BELLIED SPIDER MONKEY Ateles belzebuth
Scarce at Los Fierros, Huanchaca II and Flor de Oro (1-2 groups seen or heard almost daily), commoner at El Encanto, La Laja and Lago Caiman (2-4 groups seen or heard daily) (T)

KINKAJOU Potos flavus
3-4 seen or heard on night-walks at El Encanto (T)

CRAB-EATING RACCOON Procyon cancrivorous
Tracks seen at Los Fierros (forest edge and pampa, around puddles on the road), and at El Encanto

CRAB-EATING FOX Cerdocyon thous
Very common at night around the airstrip at Los Fierros and along the road across the pampa. Usually at least 1-2 seen per hour of night-walking, more while driving

MANED WOLF Chrysocyon brachyurus
One glimpsed briefly along the pampas road at Los Fierros (7 am), another seen coming for water at 4 pm at an arroyo within Huanchaca II forest. Tracks and scats were commonly encountered along the road across the Los Fierros pampa. Probably the best way to see this animal is to be out on the pampa road from 4 pm until dusk, or between 5 am and 6 am, especially when puddles have collected on this road after rain attracting the thirsty wolf. Patience required. On more than one occasion we walked out across the pampa at 5 pm and back at 6.30 to find fresh wolf tracks or wolf turds laid thoughtfully in our footprints

TAYRA Eira barbara
One seen on the road near Los Fierros, another seen up a tree at Huanchaca II

GIANT OTTER Pteronura brasiliensis
One group of 7 from Camino Sur at the first bahia (oxbow) south of Flor de Oro; 1-4 individuals were also seen from camp at Lago Caiman on three occasions (T)

JAGUARUNDI Herpailurus yaguaroundi
One seen well along the pampa road at Los Fierros in daylight (5 pm); tracks regularly seen around puddles on the same road

MARGAY Leopardus wiedii
One seen extremely well (it eventually sniffed one of our calves before it realised its error and bounded away) on a night-walk at El Encanto (7.30 pm). Identification was confirmed by comparing pardalis with wiedii alongside each other at Santa Cruz zoo; the latter is slighter, with smaller head, larger eyes and longer tail

[OCELOT Leopardus pardalis]
Tracks of medium-sized cats (pugs about twice the size of Jaguarundi tracks, and therefore presumably made by ocelots) were seen twice at Los Fierros, once in forest and once in pampa

PUMA Puma concolor
2-3 sets of tracks seen at Los Fierros and one individual seen at the stream near El Encanto camp (4 pm)

JAGUAR Panthera onca
Four seen: one male briefly at the dry arroyo at the far end of the pampa road towards El Encanto (6 am), one (probably female) on the road near Los Fierros lodge (8 am), one at wonderfully close range on the road near El Encanto (8 am) and one near the end of the airstrip at Flor do Oro (4 pm). Many tracks throughout, except Huanchaca II

GREY BROCKET DEER Mazama gouazoubira
One seen well on the road near Los Fierros (9 am)

RED BROCKET DEER Mazama americana
Total of around 10 seen at day and night, at both Los Fierros and El Encanto

PAMPAS DEER Ozotoceros bezoarcticus
One female seen twice (5 pm and 6 am) in grassland c.6 km east of Huanchaca II, and another female and young male seen from the track between La Laja and Huanchaca II, c.1 km from the edge of the meseta at 5 pm

CAPYBARA Hydrochaeris hrdrochaeris
One dead individual seen floating downriver on the Iténez, one seen at Piso Firme, tracks seen at Flor de Oro

WHITE-LIPPED PECCARY Tayassu pecari
One large troop heard near El Encanto camp, and a troop of around 40 seen near El Encanto waterfall; other troops were heard at Flor de Oro (Camino Sur), and recorded by smell on one occasion and tracks on another at Lago Caiman

COLLARED PECCARY Tayassu tajacu
One individual seen at Lago Caiman (aromatically identifiable from the above species)

BRAZILIAN TAPIR Tapirus terrestris
Four seen well: one at close range while night-walking at El Encanto (9 pm), then prolonged views of one in daylight on the road between Los Fierros and La Florida (8 am), and finally a large male and a smaller individual seen from a vehicle while driving to El Encanto for our second visit (9 pm). Others were regularly heard crashing through undergrowth (at least one at Los Fierros, several more at El Encanto and Lago Caiman). Tracks were seen at many locations including Flor de Oro and Huanchaca II where this species ranges far out along gallery forests and open pampa

SOUTHERN AMAZONIAN RED SQUIRREL Sciurus spadiceus
Fairly common (1-3 seen or heard almost daily) at all forested sites visited, including Huanchaca II (T)

GUINEA PIG Cavia aperea
Commonly encountered along the cerrado road, particularly at dawn or dusk

LARGE SPINY RAT Proechimys longicaudatus
One seen well on forest floor beside Camino Norte, Flor de Oro

BICOLOURED ARBOREAL RICE RAT Oecomys bicolor
Two individuals living in the roof of the "cabaña" at El Encanto camp, another (probably this species) seen along the road nearby

AMAZON BAMBOO RAT Dactylomys dactylinus
Heard occasionally at Flor de Oro and Lago Caiman

PACA Agouti paca
Seen regularly at night around Los Fierros camp and along logging roads nearby

[BROWN AGOUTI Dasyprocta variegata]
At least one agouti seen near Los Fierros camp seemed to be this species rather than the next

AZARA'S AGOUTI Dasyprocta azarae
Remarkably common around Los Fierros and often seen along roads here, and at El Encanto. Seemed absent from Huanchaca II and scarce at sites in the north of the park

NINE-BANDED LONG-NOSED ARMADILLO Dasypus novemcinctus
Diggings seen regularly, and one individual bumped into one of our bike wheels along the road near Los Fierros (7 pm)

GREAT LONG-NOSED ARMADILLO Dasypus kappleri
This impressive beast was seen extremely well as it hoovered around in roadside leaf-litter at El Encanto (8 pm)

GIANT ARMADILLO Priodontes maximus
A few diggings were seen in cerrado near Los Fierros and Huanchaca II, but this species seemed particularly common around Flor de Oro where we spent a few nights on the trails failing to find one

BOTO Inia geoffrensis
Up to 4 relatively tame river-dolphins regularly swam around the waterfront at Piso Firme (sometimes only metres from the busy bank and giving very good views in clear water below the wooden riverside lookout). A few singles were seen briefly on the Bajo Paragua and Iténez rivers when travelling by boat between Piso Firme and Flor de Oro.

ORNATE HAWK-EAGLE Spizaetus ornatus
Several sightings at Los Fierros of adults and juveniles (a traditional nest is located along the airstrip); an adult was seen at a nest at La Laja, and adults were heard and seen displaying at El Encanto. The local guides or park guards often talk of Harpy or Harpia nests, at Los Fierros, La Laja and Flor de Oro; the three we visited were not occupied by Harpy Eagles Harpia harpyja, but Ornate Hawk-eagles (T)

RED-THROATED CARACARA Ibycter americanus
Scarce at Los Fierros (heard or seen once every 3-4 days), fairly common at El Encanto, Flor de Oro and Lago Caiman (heard or seen daily) (T)

Small numbers (roughly a pair every day or two) regularly seen or heard at Los Fierros, Piso Firme, Flor de Oro and Lago Caiman (T)

SOUTHERN CRESTED-CARACARA Polyborus plancus
One near La Mechita, several around Piso Firme and daily at Flor de Oro

YELLOW-HEADED CARACARA Milvago chimachima
1-3 most days in cerrado and grassland around Huanchaca II (T)

LAUGHING FALCON Herpetotheres cachinnans
Never seen, but 1-2 heard at dawn and dusk on many occasions at Los Fierros, Flor de Oro and Lago Caiman (T)

BARRED FOREST-FALCON Micrastur ruficollis
Heard only at Los Fierros, and possibly at Huanchaca II

"LINED" FOREST-FALCON Micrastur "gilvicollis"
One adult seen at close range near El Encanto camp (this form is apparently set to be elevated to full species as calls differ from true gilvicollis)­­; calls were often heard of this form near the airstrip trail at Los Fierros, but it was difficult to see in the dense forest (T)

APLOMADO FALCON Falco femoralis
Singles on two occasions at Los Fierros pampa and once near Flor de Oro lodge

BAT FALCON Falco rufigularis
Fairly common at all sites visited; a pair fledged three young at Los Fierros airstrip during our stay (T)

[ORANGE-BREASTED FALCON Falco deiroleucus]
A pair of falcons nesting on the cliffs beside El Encanto waterfall was possibly this species (although we still feel it was probably a Bat Falcon). They seemed slightly larger than Bat Falcons, with a slightly deeper call, but they nevertheless seemed very similar and we thought the call differences might have been caused by the natural amphitheatre (tall cliffs on three sides) affecting sound. The identification is left unconfirmed, especially as views were distant and brief before a bird disappeared onto the nest, never to return. F. deiroleucus has been reported nesting here previously

AMERICAN KESTREL Falco sparverius
One seen twice around the escarpment above La Laja

SPECKLED CHACHALACA Ortalis guttata
2-3 seen and 2 other groups heard at Lago Caiman

RUFOUS-WINGED ANTWREN Herpsilochmus rufimarginatus
Small numbers regularly heard at Los Fierros, El Encanto, La Laja and Lago Caiman (usually 1-4 individuals daily); seemed much commoner on the meseta at Huanchaca II (10-20 heard daily) but despite regular checking we never found Large-billed Antwren Herpsilochmus longirostris which occurs at the same site (T)

RUSTY-BACKED ANTWREN Formicivora rufa
c.5 seen around the Los Fierros pampa, c.4 seen at Huanchaca II (T)

[ZIMMER'S TODY-TYRANT Hemitriccus minimus]
We didn't find this species at Los Fierros or Flor de Oro despite speculative playback in likely looking short-stature forest on sandy soils; fieldwork constraints meant that we only had a few hours in this habitat type. Zimmer's Tody-tyrant presumably lives in the stretch of woodland after the pampa on the road between Los Fierros to El Encanto, and also near Flor de Oro. At the latter, take the trail that runs alongside the far side of the airstrip - ie parallel to Camino Sur - until it forks c.400 m beyond the end of the airstrip. If you go to the right there are two patches of stunted forest before you hit the pampa again. We saw Spotted Puffbird here (another species that prefers stunted forest in these parts) and I'm certain minimus would be found here without too much trouble.

FLAMMULATED BAMBOO-TYRANT Hemitriccus flammulatus
Fairly common at Los Fierros, El Encanto and La Laja (1-5 heard daily), commoner at Huanchaca II, Flor de Oro and Lago Caiman (5-15 heard daily) (T)

Heard occasionally in dense riverine or lakeside undergrowth: once at Piso Firme, once at Flor de Oro, once at Lago Caiman

[RUFOUS-SIDED PYGMY-TYRANT Euscarthmus rufimarginatus]
We searched for this threatened species all around the Huanchaca II forest island, trawling across miles of campo limpo, campo sujo and cerrado with a canned recording - but to no avail. This bird is apparently much easier to find at Huanchaca I, but in any case the large population reported in Ridgely and Tudor appears not to exist.

RUFOUS-TAILED FLATBILL Ramphotrigon ruficauda

GREYISH MOURNER Rhytipterna simplex
Fairly common at Los Fierros, El Encanto and La Laja (2-5 seen or heard daily), less common at Huanchaca II and Lago Caiman (1-3 seen or heard most days, regularly accompanying mid-storey flocks) (T)

CINEREOUS MOURNER Laniocera hypopyrra
Seen on fewer occasions than the preceding species (although this is perhaps because it less frequently visits the understorey or joins flocks), but nevertheless quite common at Los Fierros, El Encanto, La Laja and Lago Caiman (where leks or single birds were heard roughly once a day) (T)

SHORT-CRESTED FLYCATCHER Myiarchus ferox
Common at Flor de Oro where c.5 seen and many heard (T)

STREAKED FLYCATCHER Myiodynastes maculatus
2-3 were seen at the beginning of our visits to both Los Fierros and El Encanto, and a single individual was found at Huanchaca II, but these were presumably departing austral migrants as numbers appeared to dwindle and there were no sightings in December

Fairly common by voice (2-6 heard daily) at Los Fierros, El Encanto, La Laja and Lago Caiman (T)

CROWNED SLATY FLYCATCHER Empidonomus aurantioatrocristatus

2-3 seen early in our stay at Los Fierros (probably migrants)

SULPHURY FLYCATCHER Tyannopsis sulphurea
One individual seen perching in the open sub-canopy of disturbed forest c.500 m from Lago Caiman; this bird was not directly associating with palms although a few palms stood nearby

WHITE-THROATED KINGBIRD Tyrannus albogularis
10-20 were seen in canopy at the edge of Huanchaca II, and foraging along narrow strips of gallery forest where they sometimes outnumbered Tropical Kingbirds. As White-throated Kingbirds were singing, interacting agonistically, and apparently nest prospecting, it seems likely that this species breeds at the site

A few were seen around Piso Firme, but none around Flor de Oro or Lago Caiman

BLACK-CAPPED BECARD Pachyramphus marginatus
One female seen at Los Fierros, and the dawn song was heard daily given by two or more individuals along the main trail at Lago Caiman (T)

PINK-THROATED BECARD Pachyramphus minor
Seemed scarce; one young male moulting into adult plumage was seen with a mid-storey flock at El Encanto

WHITE-WINGED BECARD Pachyramphus polychopterus
Fairly common at most forest sites visited, particularly in edge situations; regularly heard (2-4 daily) at Los Fierros, El Encanto and Piso Firme, a little less frequently at Huanchaca II (1-2 most days), but more commonly at Flor de Oro and Lago Caiman (4-10 daily); individuals quite often seen accompanying mixed-species flocks (T)

Difficult to find, the only sightings being along the airstrip trail (Los Fierros) where a male and female were seen on three occasions

FIERY-CAPPED MANAKIN Machaeropterus pyrocephalus
One male was seen along the airstrip trail (Los Fierros) and a female was seen along Camino Sur at Flor de Oro; its true abundance was more accurately indicated by the male's strange frog-like pink note which was regularly heard (3-8 times daily) at Los Fierros, El Encanto, La Laja, Huanchaca II and Flor de Oro (T)
