Indian Birds Vol. 6 No. 1 (Publ. 25th June 2010)14
We regularly visit vast marshlands, and water bodies, for winter waterfowl counts around Santhemaralli where Jugal Tiwari recorded the White-naped Tit (Tiwari 1999). We have not observed the White-naped Tit here, just the Great Tit, near the waterbodies, on a few occasions. P. nuchalis is known to move over 5–7 km for foraging if the forest is fragmented, and thus may cover larger distances in search of food. Ringed birds in Kachchh, Gujarat have been recaptured some 5–7 km away from the place of ringing (Jugal Tiwari, pers. comm.).
Although we noticed that P. nuchalis was not a difficult bird to spot in suitable habitat, we do not conclude that the species is common in the area. In the recent past, efforts to survey the interior regions of the Male Mahadeshwara Hills, and nearby areas, for the tit were severely hindered due to limited access and the presence of poachers, and security forces. We plan to conduct surveys in future to look for the species more intensively in the area. Observations of the species from the nearby Chittoor district in Andhra Pradesh (Table 1; Fig. 4) indicate that the distributional range of the species could be much wider in southern India, but that it may be found in small numbers in large tracts of fragmented habitats. Future threats to the tit’s habitat at Male Mahadeshwara Hills could include quarrying for granite, and habitat loss.

Editorial Committee’s note:The two records of Uttangi (1994, 1995), of P. nuchalis from the evergreen to semi-evergreen biotope at Anshi National Park, and in the residential backyard of Dharwad town, need confirmation, and hence have not been included in the above paper. In addition, the habitats where he saw the birds do not fit the typical Albizia or Acacia dominated open jungle found in southern Karnataka (especially the Cauvery Wildlife Sanctuary belt (Lott & Lott 1999) / Andhra Pradesh (Jones 2007), although it is stated that the Dharwad locality is at the edge of a transitional belt of thorn forest. Also, the Wynaad record of the species (Zacharias & Gaston 1993) is not confirmed as yet, and it is indicated that the identification of P. nuchalis during one of those Wynaad surveys, when the species is claimed to have been sighted, is doubtful (V. Santharam pers. comm., also Sashikumar et al., 2010, confirming the former).

Results & discussion Thirty-fourbirdspecieswererecordedfromtheJagatpurwetlandduring the study. They belong to 12 families and eight orders. About79%oftherecordedavifaunaiswetland-dependent.Outof34spp.,21wereresident(61.76%),sevenlocallymigrant(20.58%),andsixmigrant(17.64%).
Itisnoteworthythatfourspeciesofstorks(Ciconiidae)occurin Jagatpurwetland.According to IUCN (1996) andBirdLifeInternational (2001),GreaterAdjutant StorkLeptoptilos dubius has been categorized as Endangered (En), LesserAdjutantStork L. javanicus asVulnerable (Vu), andBlack-neckedStorkEphippiorhynchus asiaticusasNearThreatened(NT).20GreaterAdjutantStorks,comprising13adultsandsevenimmaturebirdswereseeninMarch–Aprilwhenthewetlandwasreceding.Twobirdshadgularpouches.GreaterAdjutantstorksarethelocallymigratorywetlandspeciesofspecialconservationinterest,andarerestrictedtotheAsia-Pacificregion.Beingendangered,theyfaceaveryhighriskofextinctioninthewildinthefuture(Collaret al.1994).Theglobalpopulationestimate(restrictedtoAsia-Pacificregiononly)forthebirdislessthan700(Perennouet al. 1994).AccordingtoAsadR.Rahmani,Director,BombayNaturalHistorySociety(pers. comm.),GreaterAdjutantshavenotbeensightedoutsideAssaminrecentdecades.Inviewofthis,theirpresenceinandaroundJagatpurwetlandisimportant.Itisalsosignificant that thenumber (20) sighted in JagatpurwetlandfulfillstheRamsarCriteriaof1%forthewetlandtobeproposedaRamsarsite.IntheGangeticfloodplains,Black-neckedStorkshavenotbeenreportedinrecentyearsoutsidethestateofUttarPradesh.Our observation suggests that Biharmay still havepopulationsofthisdecliningstork.
Our survey reveals that Jagatpurwetland is quite rich inaviandiversity.Thewetland,atpresent,isundervariousthreats.Availability ofwater, inflowofpesticides and fertilizers fromthesurroundingagriculturalfields,weedgrowth,particularlyofwaterhyacinth, extensivefishing, and thehuntingofbirdsforpleasure are among themajor threats to thewetlandandits avifauna. For conserving the Jagatpurwetland and itsrich biodiversity, amanagementplan should beprepared insuchamannerthatattheobjectivelevelitprimarilyprovidesemphasisonprotectingthewetland,andatthesecondarylevelitprovidesanavenueforsustainableutilizationofresourcesofthewetlandwithoutjeopardizingitscontinuedecologicalvaluesandfunctions.

Thick-billedGreen-PigeonTreron curvirostra is a resident bird in theHimalaya—fromwesternNepal eastward toSikkim, north Bengal duars and Bhutan, to extreme eastern
ArunachalPradesh—asalso in thehillsofnorth-easternIndia,southoftheBrahmaputraRiver.Itaffectswell-woodedareasandforestsfromplainstoatleast1,500ma.s.l.(Ali&Ripley1987).ItsoccurrenceinpeninsularIndiahasnotbeenrecorded(Ali&Ripley1987;Grimmettet al.1998;Kazmierczak2000;Rasmussen&Anderton2005).Here,IreportitspresenceinSimilipalhills,north-eastern Orissa.

Theterrain is undulating, the altitude ranges from300to1,200ma.s.l.,andforesttypesincludedrydeciduous,moistdeciduous,and semi-evergreen. Some authoritiesconsider Similipal a part of the EasternGhats(Sinha1971),whileotherstreatitasthe south-eastern extension of the Chota NagpurPlateau(Ray2005).Thearea fallsunder theprovinceof ‘Chhotanagpur’ intheDeccanPeninsulabiogeographiczoneofRodgers&Panwar(1988).DespitebeinganImportantBirdArea(IBACodeIN-OR-06),itsbirdlifeisnotwelldocumented(Islam&Rahmani2004).

These observations, which spreadthroughouttheyear,seemtoindicatethatthe species ismost likely a rare residentinthehillsofSimilipal,andconstitutethefirst records of the species’ presence inpeninsular India.This also supports theputative role of the SimilipalHills as alink between the forests of north-eastern India,andthoseoftheWesternGhats.ThenorthernEasternGhatsarestillrelativelyunexplored, and intensive investigationsalong the unexplored patches of theserangesmight revealmore occurrencesof unrecorded birds fromnorth-easternIndia.

IntroductionTheLesserFloricanSypheotides indicus is the smallest bustard (Otididae) in theworld (Fig. 1). It is endemic to the IndianSubcontinent, and listed asCritically Endangered (Collar&Andrews 1994), and is a Schedule I speciesunder the IndianWildlife(Protection)Act,1972.ItsbreedingrangeisconfinedtoIndia(Ali&Ripley1983).ItiscommonlyseenduringthemonsoonineasternRajasthan,andGujarat.Itinhabitstallgrasslands,withscatteredbushes,andstandingcropsofcotton,andmillet(Ali&Ripley1983).ItsestimatedpopulationinIndia,in1999was3,530birds(Sankaran2000).Sankaran(1996)listedPratapgarhasthemost importantareaforLesserFloricaninsouthernRajasthan.However,detailed information is not available regarding thestatus,anddistributionofthisspeciesfromhere(Sankaran2000).Thisstudypresentsthecurrentstatus,anddistributionofLesserFloricaninPratapgarhdistrict.
Study areaThe present studywas conducted in theKariawad area ofPratapgarhdistrict,Rajasthan (24º08’N 74º47’E),which is anextension of the Malwa Plateau in Rajasthan. Other areas of Pratapgarh, includingSidhpura,Bajrangarh, andMowdikherawerealsosurveyedforLesserFlorican.Treecoverinthisregionis negligible except for scatteredgrowthofButea monosperma

Thetermkleptoparasitism,or‘parasitismbytheft’,isusedinecologytodescribea“strategyofstealingitems,suchasfoodornestmaterials,fromotherindividuals”(Sibley2001).

Sreekar&Srinivasulu(2010)erroneouslystatethatKannan’s(1993) record of theYellow-throatedBulbulPycnonotus xantholaemuswasfromKerala.Infact,aspointedoutinthe
note,thesightingwasnearAliyarDamnearValparai(whichisatea-townintheCoimbatoredistrictofTamilNadu),rightbyaroadsidewaterfallalongthebusyPollachi–Valparaihighway.Theauthorsapparentlysawtheword“Anaimalais”inthetitleandassumed,assomepeopledo,thatthelocationwasinKerala.AlargeportionoftheAnaimalaiHills(includingthe1,250km2IndiraGandhiWildlife Sanctuary,withinwhichKannan’s sightingoccurred)liesinTamilNadu.
Thisbringsintoissuetheneedformoreself-explanatorytitles,especially for shortnotes. In thisageof the informationsuperhighwaywithreadyaccesstotitlesandcitations,butoftennotwholedocuments,authorsoftenyieldtothetemptationtocitefromtitleswithoutreadingthewholepaper.Sometimesauthorsareunable(orsimplytoobusyorlazy!)tolookuptheoriginalpapers and therefore resort to citing from secondary sources.TheaforementionederrorcouldhavebeenavoidedhadKannantitledhisnote“YellowthroatedBulbulintheAnaimalaiHillsof Tamil Nadu”(italicsappliednowforemphasis).Instead,heleftitdubiously,withouttheitalicisedpart,thusleavingitopentobemisconstrued.Similarly,Mehta’s(2010)“PossiblesightingofanOrientalHoney-BuzzardPernis ptilorhynchus orientalis”couldhaveendedwith“….nearJalpaiguri,WestBengal.”
Someauthorsinapparenthastemerelyglance at a title and jump into egregiously erroneous conclusions. Sengupta (1976:340,1982:71)incorrectlycitedInglis(1910:985)ashaving“foundtheCommonMynafeedingonPiedMyna(Sturnus contra).”Infact,Inglishadreported,“CommonMynafeedingyoung of Pied Myna”(italicsours).WereportedthisinourmonographontheCommonMyna(Kannan&James2001).
Sometimestitlescanjustbewrongandtheerrorcanonlybefounduponcloseinspectionofthepapers.Darwin(1871:778),quotingHorne(1869)reported,“TheFemaleHorn-bill(Buceros)…plastersupwithherownexcrementtheorificeoftheholeinwhichshesitsonhereggs.”HornehoweverwasactuallyreferringtotheIndianGreyHornbill,Meniceros birostris(nowOcyceros birostris),butwhichheerroneouslynamedM. bicornis.DarwinperpetuatedtheerrorwhenheincorrectlyassumedHornewasdescribingtheGreat Hornbill Buceros bicornis!(James&Kannan2007).
Most titles that startwith “Unusualnest of…” couldbereworded to reflecthowunusual thenestwas.Bhardwaj et al. (2008)couldhavetitledtheirpapersimply,andmoreeffectively,“CrestedBuntingMelophus lathaminestinginalowbush.”Iftheauthor(s)feelscompelledtorefertotheanomalousnatureofthenestinthetitle,somecleverchoiceofwordsmayhelp,like“Anunusualbush-nestof theCrestedBunting…”SeeBradley&Cooke(2001)foranexampleofsuchatitleintheliterature.
Errors that enterpublished literature are verydifficult to
expungeor rectify.Titles that convey thegist of thefindingsare more likely nottobemisinterpreted.“WildGreatHornbillsdonotusemudtosealnestcavities”(James&Kannan2007)ismuchbetterthananebulous,“OnthenestsealingmaterialusedbywildGreatHornbills”.Similarly,“HouseSparrowsassociatedwithreducedCliffSwallownestingsuccess”(Leasureet al.2010)ismuchlesslikelytobemisconstruedthanthestandard,“EffectofHouseSparrowsonthenestingsuccessofCliffSwallows.”Both thesepapersdonot force the researcher to huntdowntheentirepaper.Althoughreadingthewholepaperisalwaysadvisable, stating themainfindingunequivocally,wheneverpossible,inthetitle,reducesthelikelihoodofthepaperbeingmisinterpretedbysomeonewhodidnot(orcouldnot)accesstheentiredocument.
