|A Report from birdtours.co.uk|
Cristalino Jungle Lodge and Alta Floresta, Brazil, April - June 2004,
FL spent the period 28 March - 27 June 2004 as a voluntary guide at Cristalino Jungle Lodge (CJL) and JT (and Nathalie Tobias) worked at the same site as a researcher for the period 26 May - 27 June 2003. This report contains details of their bird and mammal records, plus background information intended to be of use to anyone visiting or volunteering at Cristalino.
English-speaking birders are required as volunteers all year round, but must be prepared to spend three months at the site. This is adequate to see the majority of the birds that occur in the pristine forests along the Rio Cristalino. Voluntary Englsih-speaking guides, who must be committed to stay at least three months, receive free accommodation and food and are free to explore the forest when there are no tourists. The main tourist season is from July-September, though the best birding months are probably May-August. It rains heavily from December to March, causing the river to rise and flood the igapo forest. Rainfall declines markedly during March and the water-level rapidly drops.
Most birders who come to Cristalino spend far too little time there - usually a week or less - and only see a small fraction of the birds present. Whilst the cost of staying a few extra days may seem prohibitive, the rewards are well worth considering. Don't forget that the cost is for full board and includes boat trips that provide the chance to see a variety of birds that are difficult from forest trails. The 50m-tall tower is higher than any of the nearby trees and offers fantastic opportunities to see canopy birds well. Moreover, the more times you climb the tower for a supracanopy session the higher your chance of seeing a Harpy, Crested Eagle or other rare raptor, not to mention other scarce canopy birds.
We would recommend staying at Cristalino for 10 days to two weeks if you can. Many people combine the trip with the Pantanal and Chapada dos Guimaraes, but if you are organized, those areas combined should not take more than 5-6 days of your time. There is now a direct flight from São Paulo to Alta Floresta and you can be in the forest around the lodge the same day you leave São Paulo or Cuiabá. Flying from Cuiabá (gateway to the Pantanal and Chapada) to Alta Floresta takes less than two hours by plane, or overnight on the bus.
The lodge itself and facilities are very comfortable and the food is excellent. There is a good library at the lodge that has a useful selection of books for birders (both volumes of Ridgely and Tudor, Birds in Brazil, Birds of Ecuador, Dunning's Photographic guide, Birds of Colombia text), as well as a smattering of guide books on reptiles and amphibians, mammals and butterflies. The library depends laregly on donations, so if you have anyrelevent books that you don't need, take them with you. A generator provides electricity for a few hours in the evening; sufficient to charge up digital cameras and to download photos if you have your computer.
In the following systematic list, all records refer to areas around the Cristalino Lodge unless otherwise stated. Trails mentioned here equate to those documented in the Samuel Hansson report. There is one additional trail that runs from the Rochas trail (near the Saleiro) to the Rio Teles Pires. This has yet to be named, but for the sake of convenience we call it the New trail. Another area of interest is the so-called Secret Garden, a patch of open rocky habitat (similar to the Serra) situated some 50 m from the main lodge clearing and best reached by a narrow trail that forks left off the Rochas trail before it reaches the large rocks. A similar patch of rocky, Serra-type habitat is found at the far end of the Caja trail.
The Teles Pires is a white-water river; the Cristalino is a black-water river. This difference is caused by underlying sedimentation (black water being related to a sandy catchment) and underlies some differences in avifauna. In terms of biogeography, and despite being fairly narrow, the Rio Teles Pires is an important waterway marking the distributional boundary between several related forms of birds and mammals.
Away from Cristalino, other sites mentioned in this report are defined as follows:
Hotel Fragment: a 50 ha plot of degraded forest accessible on the grounds of the Hotel Floresta Amazonica in Alta Floresta, part of a larger patch of maybe 200 ha surrounded by cleared land. Birding in the Hotel Fragment is relatively quiet, and few birds form the understorey or canopy flocks so characteristic of the main forest. Nonetheless, it does contain a surprising variety of birds and even rarities like Crested Eagle are still turning up. Some widespread species can be found in the Hotel Fragment more readily than at Cristalino (eg Chestnut-tailed Antbird, Short-tailed Pygmy-tyrant) but our advice is to maximise time at Cristalino Lodge.
Fish Ponds: within a five minute walk of the swimming pool at the Hotel Floresta Amazonica there is an area of wetlands and fish ponds with wet marshy habitat and standing palms adjacent to forest. Here one can see many parrots and various waterbirds, including crakes.
Main Road: the road north of Alta Floresta, c.20 km of which must be driven en route to Cristalino. The first section of road passes through highly degraded agricultural land; the last 5 km passes a narrow Mauritia palm swamp (famed for its palmcreepers) and several patches of degraded bamboo-dominated woodland.
Fazenda Track: a right turn from the Main Road passes through a wooden gate and leads to a c.10 km dirt track through a fazenda, leading down to the Rio Teles Pires. From the end of this track (reached in one hour from Alta Floresta), boats leave for Cristalino Lodge, taking c.25 minutes to get there. The last 5 km of the Fazenda Track goes through relatively intact tall forest with a significantly different avifauna to that found at Cristalino. The Borboletas trail runs from the track to the Rio Teles Pires and has similar birds.
The Island: a wooded island midstream in the Rio Teles Pires, c.300 m downstream from the entrance to the Rio Cristalino. There are some islets with shrubby vegetation found nearby. The fazenda, the island and Cristalino itself all fall within land owned and managed by Dona Vitória da Riva Carvalho.
Vocal activity was relatively slack throughout our visit, but most mornings were busy between 05:30 and 08:00. Afternoons tended to be much quieter and often best spent on the river or tower. In all cases, good birds could be found at any time of day with perseverance. The forest gradually became drier towards June, and species such as tinamous became easier to see when the leaf litter was dry, though still not easy! May was particularly pleasant since the weather was generally dry but not too hot and birding was comfortable at all times of day; and since there are few visitors at that time one can walk anywhere in the knowledge that the trails have not been recently disturbed. Most of the birding tour companies visit between June and August.
If you visit in April or May, rubber boots would be useful for birding along trails where patches of floodwater remain, though most of the time you would not need them. The flooding, however, does not inhibit birding too much, and the Zigzag Heron is perhaps most easily seen during this part of the year (it breeds in March-April). The water level receded rapidly and all trails could be walked by the end of April.
There are very few mosquitoes at Cristalino compared to most Amazonian sites that we have visited, and there is reported to be no malaria, yellow fever or leishmaniasis. Conversely, biting ticks seem to be more common than elsewhere, especially when walking off-trail. Visitors should tuck in socks and shirts, and apply insect repellant to avoid occasional infestation. Sandflies near the river can also be a nuisance at times, though they are easily deterred with insect repellent.
A telescope and tripod are virtually essential for the tower, where digiscoping is also possible. Although there are two telescopes and tripods at the lodge, they are not in good condition and we would not recommend relying on them.
Many of the birds mentioned below are relatively common and exact sites are not given for these since they could potentially be found almost anywhere in the forest. Since we were familiar with many of the birds at Cristalino we did not make a serious effort to see all those that we heard (most tinamous and tyrant-flycatchers, for example).
Some species on the list for Cristalino (available at the website) have been reported on the basis of poor views or inadequate documentation. Hence their occurrence requires confirmation (B. Whitney, pers. comm.). If you find any of the following, therefore, it would be worth attempting to document the species by recording the voice or obtaining photos/videos. These species include: Guianan Gnatcatcher (Polioptila guianensis), Lined Forest-falcon (Micrastur gilvicollis), Black-bellied Gnateater (Conopophaga melanogaster), Red-billed Scythebill (Campylorhamphus trochilirostris) and any species of bushbird (Clytoctantes/Neoctantes).
FL intends to lead one or two private fixed-date bird and butterfly tours to Cristalino during late May and/or June 2006. If you are interested in this, please contact me on email@example.com for more information.

Blue-and-Yellow Macaw (Ara ararauna) Uncommon but regular, with small numbers occasionally encountered around the Hotel Fragment, along the Fazenda Track and the lodge clearings and visible from the tower.
Scarlet Macaw (Ara macao) The most common macaw, seen easily from the tower, with as many as 40-50 gathering in groups during the second half of June.
Red-and-green Macaw (Ara chloroptera) More often seen than Ara macao until 10 April, but thereafter rather scarce and not seen at all from 1-20 April. Subsequently seen every week and heard every day. Also observed at the Hotel Fragment.

Blackish Nightjar (Caprimulgus nigrescens) Daily around the main and bungalow clearings. Always present on the Serra and Secret Garden.
Little Nightjar (Caprimulgus parvulus). A bird seen sallying over the Rio Cristalino at night from a perch at the edge of igapo forest on 25 June was subsequently identified as this species (based on photos), though its behaviour and habitat seem to be at odds with those described in the literature.
Ladder-tailed Nightjar (Hydropsalis climacocerca) Occasionally seen along the Cristalino and Teles Pires. Several individuals roost on or near the Island.
Spot-tailed Nightjar (Caprimulgus maculicaudus). One near the fishponds by the Hotel Fragment in Alta Floresta on 25-26 May.

White-bearded Hermit (Phaethornis hispidus) Apparently fairly common, especially near the river and along the Fazenda Track. Three individuals mistnetted on the Taboca Trail. A nest of this species built in the bungalow clearing in mid-April contained two eggs on 5 May and two nestlings on 8 May.
Eastern Long-tailed Hermit (Phaethornis superciliosus) Fairly common, especially along the New trail where one lek was situated. Two mistnetted individuals seemed referable to the subspecies muelleri (photographs checked against specimens).
Reddish Hermit (Phaethornis ruber) Common and vocal at the Hotel Fragment, fairly common on the west bank of the Teles Pires in the forest along the first part of the road towards Alta Floresta. Apparently scarce at Cristalino: a probable observed once along the Caja trail.
Streak-throated Hermit (Phaethornis rupurumii) A small, dark-throated hermit observed at close range in the Secret Garden on 14 May, and on several occasions along the New trail on 23 and 25 June, is thought to be this species. It was frequently observed visiting the large red flowers of Passifloraceae. Field photographs confirm that the bird involved belongs to the longuemareus/squalidus group of hermits, and most likely the amazonicus race of rupurumii (sometimes lumped with squalidus). This would be a rather large, if not quite unexpected, range extension.
Straight-billed Hermit (Phaethornis bourcieri). Inconspicuous. One seen on the Saleiro loop on 1 May, another on the Cacao trail on 15 June, and occasionally heard.
Grey-breasted Sabrewing (Campylopterus largipennis) Uncommon; seen only about eight times. A nest found on the Taboca trail containing two eggs on 5 May.

White-whiskered Spider Monkey (Ateles marginatus) This localised endemic is easily found in the forests around Cristalino Lodge.
Snethlage's Marmoset (Callithrix emiliae) Unobtrusive. Most regularly observed along the first part of the Rochas and the Figuera trails.
Silvery Marmoset (Callithrix argentata) Some marmosets at the Hotel Fragment show features of this species, others do not. Taxonomy unsettled.

If you spend a night at the observation hide there, or visit the Saleiro very early in the morning (pre-dawn, occasionally just after dawn), you have a very good chance of seeing one or more individuals. They are occasionally seen crossing the river or from boats along the river.
Collared Peccary (Pecari tajacu) Solitary or in small groups (maximum number seen together was 7) Not particularly common, or easy to see well, but occasionally encountered. Visit the Saleiro regularly as the forest dries out, during the day.

The diversity and abundance of butterflies that can be observed at Cristalino is truly awesome. Many are depicted at www.neotropicalbutterlies.com
First and foremost we would like to thank Dona Vitória da Riva Carvalho for giving us the opportunity to work at Cristalino, and for all her help (along with Zuleica Melo) throughout our respective stays. We also thank the staff at CJL - particularly Francisco - and at the Hotel Floresta Amazônica for their kindness and support. We also extend our gratitude to Will and Gill Carter for their generousity and friendship and for sharing with us their expertise on plants and butterflies, as well as their limited supply of Bacardi and Coke.
