the first record of CochabambaMountain Finch Compsospizagarleppi from dpto. Chuquisaca,c.275 km south ofthe closestknown locality.

Figure I. Map showing the new locality (open square with arrow) for CochabambaMountain Finch Compsospiza garleppi in Chuquisaca. The modelled range is shownin green and the barred polygons represent priority areas to search for C garleppi.The range of Tucuman Mountain Finch C baeri is shown in blues.

Short ommunications

C. garleppi is endemic toBolivia, occurring at 2,700-3,900m in the transitional zone betweenthe Inter-Andean Dry Valleysand Puna life zones3. Its knowndistribution comprises 25 localitiesin dptos. Cochabamba andPotosi39. t inhabits semi-humidmontane scrub, in valleys withravines and scattered Polylepisand lnus trees. CochabambaMountain Finch is listed asEndangered, owing to continuedhabitat loss within its small andfragmented range3On 13 August 2012, nearthe locality of rganos Punta,Chuquisaca, in south-centralBolivia (2017'8 6452'W; Fig.1), we observed two C. garleppi(presumably a pair) in a ravine,flying fast between smallbushes and perching for a fewseconds (Fig. 2). The birds fedbriefly on the ground and thendisappeared. The ravine wherethe observation was made is inthe Boliviano-Tucumano Ceja deMonte scrublands (e.g. Baccharissp., Echinopsis sp., Salvia sp.),just above the Ceja de Montesubhumid-humid woodland(including Potylepis cristagaZZi ,within the transitional zonebetween semi-humid puna and theInter-Andean Dry Valleys12.14. Theravine is c.40 m from a dirt roadand is characterised by patches of2-3 m-tall scrubs within a matrixof grassland, and some rockyoutcrops (Fig. 3).Herzog et at. modelled thepotential distribution of C.

garleppi (Fig. I), indicating thatthe species range extends south asfar as northern Potosi, in the areaadjacent to extreme north-westChuquisaca. Likewise, based onrecords and environmental data,Guerrer0 9 modelled a similar rangeand suggested that, although lesslikely, the species range couldextend north-west as far as LaPaz and to the south throughoutcentral Chuquisaca as far asTarija. Our record demonstratesthat its distribution reachessouthern Chuquisaca and couldextend much further to the souththan previously suspected.Although no specific localityis mentioned, surveys forCochabamba Mountain Finchin areas of suitable habitat inChuquisaca in the early 1990sfailed to record the speciesB Ourobservation, made during a shortsurvey, suggests that furthereffort is needed to detect thespecies in southern Bolivia, andindeed elsewhere in the country.For example, it is thought thatpopulations in Cochabamba andPotosi-separated by c.70 km-areisolated by geographic barriers(e.g. the rio Caine) and the lackof suitable habitat2; accordingly,the birds in Chuquisaca couldrepresent a different population,as the locality is >200 km south ofthe closest record and separated by

a vast area with limited suitablehabitat, although surveys areneeded to confirm this.Ornithological surveys are alsorequired to check if the speciesreaches dpto. La Paz and if itoccurs in the border area betweendptos. Cochabamba and Potosi, aswell as between the new localityin Chuquisaca and sites in Potosi,and to the south of the new localityin Chuquisaca, as far as dpto.Tari ja (Fig. 1). Iyforeover, geneticstudies are needed to assess therelationships and connectivityamong the species populations.Another issue raised by ourobservation is the possibility thata contact zone between C. garleppiand Tucuman Mountain FinchC baeri exists. In Bolivia, theVulnerable and closely relatedC. baeri, which occurs in similarhabitats, has been recorded onlyin south-east Tarija5 (Fig. 1).Surveys south of the new localityfor Cochabamba Mountain Finchin Chuquisaca, in addition toattempting confirm the presenceof this species, should also searchfor C. baeri north of its currentlyknown distribution.We recorded 25 other birdSJlElCLC S during two hours at

rgUIlIOS Punta, including threeNear Threatened and sevenrestricted-range speciesIO Basedon the Al and A3 criteria for theselection of Important Bird AreasOBAs)6, the area around the newlocality for C. garleppi could beproposed as an IBA With onlytwo national and three municipaldepartmental protected areas,large parts of Chuquisaca areunprotected7 The presence of anIBA in this region could focusfuture ornithological studiesparticularly on CochabambaMountain Finch-and strengththe organisation of the protectedarea system towards effectivebiodiversity conservation.cknowledgementsWe thank Peter Hosner whoprovided valuable suggestions that
