Summary. Rainforest habitats dominated by arborescent bamboo of the genus
Guadiia are common in south-west Amazonia. We gathered data on the avifauna
associated with this type of forest in south-west Brazil, in eastern Acre, during
November 2006. Birds were surveyed using mist-netting, observations and
recordings ofvocalisations, and a total of266bird species was recorded, 20 (7.5%)
of which are considered to be strictly associated with bamboo forest. Our survey
also extended the known ranges of several bamboo forest specialist species in
south-west Amazonia, and confirmed the importance of this habitat type for
regionalbiodiversity.
Open forests dominated by arborescent bamboo of the genus Guadiia cover some
180,000 km^ of the south-west Amazon basin, including south-east Peru, northern Bolivia
and western Brazil (Nelson et al. 1997, Silveira 2005). In the Brazilian state of Acre, these
bamboo forests are known as tabocais, and form a mosaic of habitats together with
Ombrophyllous open forest with palms, open floodplain rainforest and dense rainforest
(Acre 2000). Amazonianbamboo forests are unique ecosystems with a rich fauna ofverte-
brates (Conover 1994, Servat 1996, Kratter 1997, 1998, Lebbin et al. 2007) and invertebrates
(Conover 1994, Louton et al. 1996).
Somebird and mammal species are considered tobebamboo forestspecialists, and are
onlyfoundinareaswherethistypeofforestispresent(Kratter 1997,Haemig2006a,b). Stotz
et al. (1996) identified 29 bird species in the southern Amazonbasin that are closely associ-
atedwiththese tabocais, althoughthisnumbermaybeanunder-estimate, whichhypothesis
is supported by the recent discovery of a new bird species, Rufous Twistwing Cnipodectes
superriifus,whichisrestrictedtobambooforests (Laneetal.2007,Tobiasetal. 2008). Thisdis-
covery further emphasises the need for more detailed studies of the unique, but poorly
known fauna ofthesebamboo forests.
With the aim of providing more reliable information on the bird fauna of this type of
habitat, we conducted an ornithological expedition to the eastern portion of the Brazilian
state ofAcre. In addition to a general overview ofthe studyarea and the data collected, we
present an annotated list of the records of the species most relevant to understanding the
ecological characteristics ofthis unique forest type.

Transacreanahighway,intheeastoftheBrazilianstateofAcre (09°54'16.5"S, 68°28'26.6"W;
Fig. 1). Ornithological surveys were conducted on 11-23 November 2006, at the start ofthe
rainy season, in an area of open terrafirme forest dominated by bamboos associated with
palms. The area surrounding the forestismainlycattlepasture, withscatteredplots ofsub-
sistence agriculture. The forest has been subject to selective logging of hardwood trees by
local residents in recent years, forboth subsistence and commercial purposes.

Surveys. The inventory used two complementary approaches. Quantitative sampling
was conducted using ten 36 mm-mesh mist-nets, 2 m highby 12 m long, whilst qualitative
records were made using binoculars, and recordings of vocalisations were made using a
Sony TCM 5000 tape-recorder. Recordings willbe deposited at the Museu Paraense Emflio
Goeldi (MPEG) inBelem, Para. Mist-netswere setalongtransectswithintheforest,remain-
ing at each location for three days. The nets were opened at dawn (05.30 h) and were
generally kept open until 15.00 h, to maximise the number of captures. In some cases,
voucher specimens were collected in order to confirm the presence of the species in the
study area. These specimens were prepared using standard taxidermy techniques.
Collection ofspecimenswas authorisedby the Brazilian FederalEnvironmentInstitute
AM
(IB A) through licence number 044/2006-COFAN. All specimens are deposited at the
MPEG. Nomenclature follows that of the Brazilian Ornithological Records Committee
(CBRO 2008).
Results
A totalof266birdspecies (Table 1)wasrecordedduringthe 12daysofsampling,which
encompassed 916 net-hours of mist-netting and eight hours of recording. Twenty of the
species are associated with or restricted to lowland bamboo forests in south-west
Amazonia, i.e. 7.5% of the total, and almost 70% of the species recognised by Stotz ct al.
(1996) as being predominantly associated with bamboo forests of the southern Amazon
basin. An annotated list ofspecies most relevant to understanding the ecological character-
istics of this unique forest system is presented below.

Species accounts
BLUE-HEADED MACAW
Primoiiiis couloni
Restricted to part of the Inambari centre of endemism (Haffer 1978, Cracraft 1985). Tobias
&Brightsmith(2007) recentlyreviewedallrecordsfromsouth-westAmazonia,findingthat,
in Brazil, almost all records are from Acre. During the present study, MPDS observed at
leastsix flyingoverpastures orperched onpalmtrees atthe edge ofthe forest. The species'
vocalisationswererecorded twice.P. couloniisprobablyrelativelycommonineasternAcre.
PAVONINE CUCKOO Dromococcyxpavoniniis
Known inAcre from the upper rioJurua (Whittakeretal. 2002) and the Rio Acre Ecological
Station in the east ofthe state. D. pavoniniis was heard in forest almost daily, and was rela-
tively common in the middle strata. On 13 November 2006, one was collected in the
undergrowth ofbamboo forest after responding to playback. This specimen (MPEG 61235)
is the first from Acre.
RUFOUS-CAPPED NUNLET Nonnula ruficapilla
Recorded previously in Acre solely from the upper rio Jurua (Whittaker etal. 2002) and on
the upper rio Acre in the east ofthe state. Our record atJarinal is the fourth for the state of
Acre, and a specimen (MPEG 61249), collected in the undergrowth ofthebamboo forest, is
only the second from the state.
YELLOW-BILLED NUNBIRD Monasaflavirostris
RecordsfromAcrecomefromthe rioJuruainthewest (Whittakeretal. 2002) andthePurus
basinintheeast(Rasmussenetal. 2005,Aleixo & Guilherme2008). We observed thespecies
at the edge ofbamboo forest and in the canopy. It appeared to be segregated ecologically
from other Monasa, at least partially, through its preference for the canopy rather than the
understorey. Aspecimen (MPEG 61244)wascollectedon 12November2006,andisthefirst
from Acre, and only the third example ofthis species in the Goeldi Museum collection.
RUFOUS-HEADED WOODPECKER
Celeus spectabilis
FirstreportedfromAcrebyWhittaker&Oren (1999)basedonobservationsintabocaisalong
the upper rio Jurua. At our study site, several were observed foraging among bamboo
stems. We collected three birds responding to playback on 12 November 2006. On 15
November, a fourth specimen was mist-netted. These four, two females (MPEG 61254-55)
and two males MPEG 61256-57), increases the number of specimens of this taxon in the
Goeldi Museum collection to seven, all from Acre. Kratter (1997) considered the species a
'near-obligate' inhabitant oflowland bamboo forest in south-west Amazonia.
BAMBOO ANTSHRIKE
Ci/mbilaimus sanctacmariac
First recorded inAcreby Pierpont & Fitzpatrick (1983), based onone collectedbyJ. Hidasi,
in 1968, in the vicinity of the city of Rio Branco (Seringal Nova Empresa). The species was
subsequently recorded on the upper rio Jurua (Whittaker & Oren 1999, Wl^ittaker et al.
2002). Ithas an easily recognised song and is very common in forest undergrowth. C. sanc-
tacmariac was frequently observed following mixed-species flocks of insecti\ores in the
understorey. Three were collected, a female (MPEG 61295) and two males (MPEG
61293-94). This is another 'near-obligate' inhabitant of south-west Amazonian bamboo
forests (Kratter 1997).

ORNATE ANTWREN
EpinecropJnjUa ornata
Recorded throughout most of Acre (Whittaker et al. 2002, Guilherme 2007). Several were
observedforaginginmixed-speciesflocksintheundergrowthofthe tabocalatthestudysite.
We collected four specimens, three males (MPEG 61346-48) and a female (MPEG 61345).
Accordingto Kratter (1997), the speciesis a 'facultative' residentofbamboo forestinsouth-
westAmazonia.
STRIATED ANTBIRD Dnjmophila devillei
Whittaker &Oren (1999) presented thefirstrecords fromAcre, fromthe upperrioJurua, in
a riparian (vdrzea) forest with bamboo. It was subsequently recorded at Catuaba
Experimental Ranch in the east of the state (Rasmussenet al. 2005). We collected two birds
(MPEG 61349-50) thatresponded to playback. According to Kratter (1997) and Parker etal.
(1997), Striated Antbird is an 'obligate' resident of bamboo forest. In the study area, the

MANU ANTBIRD Cercomacra manu
KnownfromAcre onthebasis ofa specimen collected on the upper rioJurua (Whittaker &
Oren 1999), Manu Antbird was recently recorded at the Rio Acre Ecological Station (A.
Aleixo in litt. 2009). Ourtwo specimens fromJarinal (MPEG 61336-37) are the firstfromthe
east of the state. The species is another 'obligate' resident of bamboo forest (Kratter 1997,
Parker et al 1997).
YELLOW-BREASTED WARBLING ANTBIRD Hi/pocnemis siibflava
The first confirmed record in Acre was by B. M. Whitney in 1997 at Catuaba Experimental
Ranch {cf. Isler et al. 2007) based on visual observations and voucher sound-recordings. It
was also recorded in2001 by EG in the ZoobotanicalParkofthe FederalUniversity ofAcre
(UFAC). However, the first Brazilian specimens of this taxon were collected as recently as
August 2005 and February2006, at Rio Acre Ecological Station (Aleixo & Guilherme 2008).
On 16November2006,wecollectedamale(MPEG61308)intheunderstoreyofbamboofor-

H. hypoxantha geographically,withthe latter species apparentlyrestricted to thewestofthe
state, i.e. theJuruabasin (EG pers. obs.).
WHITE-LINED ANTBIRD Percnostola lophotes
The first records for Acre involved specimens taken on the upper rio Jurua (Whittaker &
Oren1999) and subsequentlyatRioAcreEcologicalStation (Aleixo &Guilherme2008). Our
specimen,MPEG61317,collectedintabocalatJarinalisthefirstforeasternAcre. Itisa 'near-

GOELDFS ANTBIRD Myrmecizagoeldii
Occurs throughout Acre (Whittaker & Oren 1999, Guilherme 2001, Whittaker et al. 2002,
Aleixo & Guilherme 2008). This species has an easily recognised song, and it was sound-
recorded daily during our survey. Four specimens, two females (MPEG 61311-12) and two
males (MPEG 61314-15), were mist-netted inthe understoreyof tabocal. Goeldi's Antbird is
a 'near-obligate' resident ofbamboo forests in south-west Amazonia (Kratter 1997).

RED-BILLED SCYTHEBILL Canipi/lorhamplnis twchiliwstris
Occurs throughoutAcre (Whittaker et al. 2002, Guilherme 2007). We mist-netted four spec-
imens, all males (MPEG 61273-76), in the understorey of tabocal. According to Kratter
(1997), the species is a 'facultative' resident ofbamboo forestin south-westAmazonia.
CHESTNUT-THROATED SPINETAIL Synallaxis cherriei
The only two prior records from Acre were visual and vocal (Whittaker et al. 2002, Aleixo
&Guilherme2008). On23November2006,wemist-nettedamale (MPEG 61278) inthemid-
storey ofbamboo forest. This is the first specimen from Acre.
PERUVIAN RECURVEBILL Simoxenops ucayalae
The first specimens from Acre were collected on the upper rio Jurua (Whittaker & Oren
1999). Subsequently, a specimen was taken at Rio Acre Ecological Station bv Aleixo &
Guilherme (2008). Afemale (MPEG61287),collected duringthepresentstudyindensetabo-
