PUTNI Foto: Mâris Lielkalns Agnija Graubica Ornitoloìijas nodaïas vadîtâja Putnu kolekcija 2007. gadâ: 90 sugas gada beigâs 15 sugas vairojâs Iegûti 70 mazuïi Pelçko dzçrvju Grus grus mazulis. Common crane young. 2007. gads putnu kolekcijâ bija interesants - vairâkas no sugâm pirmo reizi mçìinâja vairoties, kaut gan ne visas sekmîgi. Pirmais vairoðanâs mçìinâjums bija 2006. gadâ izveidotajam melno grifu Aegypius monachus pârim (abi putni aptuveni piecus gadus veci). Pirmâ ola tika izdçta 15. martâ, bet nâkamajâ dienâ putni paði to saplçsa. 7. aprîlî tika izdçta otra ola, kuru cîtîgi perçja. Perçjoðie putni kïuva arvien nervozâki, tâdçï nedçïu pirms gaidâmâs ðíilðanâs slçdzâm apmeklçtâjiem pieeju plçsîgo putnu kompleksam. Diemþçl apmeklçtâji kâpa norobeþojumam pâri un traucçja grifus. 29. maijâ grifi samina olu ar lielu, dzîvu embriju, kas bûtu ðíîlies pçc pâris dienâm. Ðis bija pirmais gadîjums Rîgas zoodârzâ, kad melnajiem grifiem ir apaugïota ola. Pirmoreiz ligzdoja arî sarkankakla zosis Branta ruficollis. 2004. gada rudenî saòçmâm pâri no Montièello putnu dârza Itâlijâ un 2005. gadâ - pâri no Helsinku zoodârza un vçl vienu putnu no Ebsas zoodârza Austrijâ. 2007. gada pavasarî putnus sadalîjâm divos jauktas izcelsmes pâros atseviðíos aplokos. Maija sâkumâ zosu aplokâ palikuðais pâris sâka riestot un meklçt ligzdas vietu; maija beigâs sâka perçt. 22. jûnijâ izðíîlâs pirmais câlis. Dçjumâ bija seðas olas, izðíîlâs divi zoslçni. Otrs pâris, kuru novietojâm pâvu aplokâ, izrâdîjâs abi tçviòi. Mûsu izauguðie mazuïi pçc dzimuma ir tçviòð un mâtîte, tâ ka varçsim izveidot vçl vienu neradniecîgu sarkankakla zosu pâri. Pirmoreiz mazulis izðíîlâs arî lielajâm pûkpîlçm Somateria mollissima. Trîs pûkpîïu pârus no Tallinas zoodârza saòçmâm 2004. gada augustâ, bet lîdz BIRDS At the end of 2007, there are 90 species in Riga Zoo bird collection. 15 species bred in 2007. There were also breeding attempts of several species never bred at Riga Zoo before, albeit not all of them were successful. Cinereous vultures Aegypius monachus laid a fertile egg for the first time. The pair was formed in 2006 (both birds ca. 5 years old), and this was their first laying season. The first egg (laid on 15 March) was destroyed by the pair on the next day. The second egg (laid on 7 April) was incubated by both birds readily. Towards the end of the incubation period the birds became subjected to stress and started to leave the nest for some periods of time. We closed the visitor pathway to reduce the disturbance. Nevertheless, on 29 May the pair crushed the egg that contained an alive embryo just few days prior to the hatching. Red-breasted geese Branta ruficollis nested for the first time as well. The birds were received from various sources - a pair came from Monticello Breeding and Conservation Centre in autumn 2004, another pair arrived from Helsinki Zoo, and one more bird from Raritatenzoo, Ebbs, in 2005. The pair of mixed origin was formed. On 22 June the first gosling hatched. Two young from a 6 egg clutch hatched in total, and were reared by parents. The first young hatched also to Common eiders Somateria mollissima. Three eider pairs were received from Tallinn Zoo in August 2004, but only one pair survived until the 2007, but still, the female was not very healthy. For our surprise, the nesting started. 6 eggs were laid, and on 28 June the first and only young hatched. It developed well, but unfortunately was lost due to an accident on 29 July. Just prior to this, on 6 July the adult male died from heart failure. During autumn Vulturine guineafowl Acryllium vulturinum laid eggs for the first time. Still, this year all the eggs were infertile. The year was successful for our cranes. As all the last years, Mantchurian cranes Grus japonensis bred successfully. Both of our pairs raised young - the "older pair" had 2.0, the "younger pair" - 0.1. We were especially happy for our "younger pair", as the male was hand reared in our zoo, and for the first time (the nesting occurred already for the 4th year) the bird did not express any aggression towards its chick. Common cranes Grus grus had their first clutch ever at our zoo. On 24 May a young hatched and was raised with success. Stanley cranes Anthropoides paradisaea had the first nesting attempt as well. The crane egg was laid five days after the nest-egg (a wooden egg) was put into the nest. Unfortunately the egg was infertile. Two years after previous breeding, our Black storks Ciconia nigra nested again. Three eggs were laid, all of them hatched, and three young storks were raised. Our experience shows that Black storks does not tend to breed, if there are other species that share their enclosure (in 2005 we had Ruddy shelducks housed together with storks) or if the captive environment is changed substantially (in 2006 there were net installations in Black storks' enclosure as a preventative measure againstAvian Influenza). 30
2007. gadam dzîvs palicis bija tikai viens pâris, pie tam mâtîte bija vairâkkârt ârstçta un akla ar vienu aci. Lai palikuðo pâri labâk nosargâtu no ârçjiem traucçjumiem (ko varçtu radît kaíi, sudrabkaijas u.c.), novietojâm to slçgtâ aplokâ kopâ ar gâròiem un ibisiem, un mums par lielu prieku 29. maijâ pîles izdçja pirmo olu. Lîdz 2. jûnijam ligzdâ bija seðas olas. 28. jûnijâ izðíîlâs pirmais pîlçns, kas arî palika vienîgais (vçl vienâ olâ embrijs bija gâjis bojâ, divas olas bija vanckari un divas nozuda). Lai izslçgtu jebkâdus traucçjumus, mâtîti ar mazuli pârcçlâm uz segtu voljeru ar baseinu fazanârijâ. Mazulis attîstîjâs ïoti labi, bet 29. jûlijâ gâja bojâ negadîjumâ. Vçl lîdz tam - 6. jûlijâ - no miokarda infarkta nobeidzâs arî pieauguðais tçviòð. Tâ visnotaï neveiksmîgi mums beidzâs pirmâ pûkpîïu vairoðanâs. Rudenî notika pirmais grifu pçrïvistu Acryllium vulturinum vairoðanâs mçìinâjums. Ðie putni mûsu kolekcijâ ir no 2004. gada. Pçrïvistas pirmo olu izdçja 10. oktobrî âra voljerâ. 12. un 21. oktobrî sekoja vçl pa olai. 2. novembrî putni tika pârvietoti uz iekðtelpâm, un iekðtelpâs tika izdçtas vçl èetras olas. Visas olas tomçr bija neapaugïotas. Ïoti aktîvas ðajâ sezonâ bija dzçrves. 25. aprîlî pirmo reizi olu izdçja pelçkâs dzçrves Grus grus. Tâ kâ ðî pâra tçviòð ir ïoti agresîvs un pâris reizes smagi sasitis mâtîti, mçs ðo aploku norobeþojâm no apmeklçtâjiem, lai novçrstu traucçjumus. 29. aprîlî ligzdâ bija divu olu dçjums, un putni ïoti labi perçja un sargâja ligzdu. 24. maijâ izðíîlâs mazulis, bet otra ola tika pamesta un vçlâk pazuda. Mazulis izauga par skaistu tçviòu. 19. jûnijâ pirmoreiz olu izdçja paradîzes dzçrves Anthropoides paradisea. Lîdz tam, novçrojot dzçrvju riesta dejas, ligzdas materiâla mçtâðanu, palielinâtu agresiju, mums radâs doma ielikt ligzdâ koka olu padçklim. Koka ola tika ielikta 16. jûnijâ. Ðo olu putni pieòçma un sargâja, un pçc trim dienâm tika izdçta îstâ ola. Tâ kâ abas olas atðíîrâs izmçros (koka ola bija krietni lielâka), 21. jûnijâ koka olu noòçmâm. Putni perçja ar lieliem pârtraukumiem, bet ïoti agresîvi sargâja ligzdu. Dzçrvju ola izrâdîjâs neapaugïota. Diemþçl mûsu paradîzes dzçrvju tçviòam ir amputçts spârns, kas varçtu traucçt pâroties un, iespçjams, bija iemesls olas neapaugïotîbai. Kâ ik gadus, sekmîga bija Japânas dzçrvju Grus japonensis vairoðanâs. Ðajâ sezonâ mûsu "vecais pâris" izaudzçja divus, "jaunais pâris" - vienu mazuli. Îpaðs prieks mums bija par jauno pâri, jo tçviòam, kas ir mâkslîgi audzçts Rîgas zoodârzâ, pirmo gadu (vairoðanâs notika ceturto gadu) netika novçrota nekâda agresija pret mazuli. "Vecâ pâra" ðî gada mazuïi ir tçviòi, bet "jaunâ pâra" bçrns - mâtîte, tâdçjâdi varçsim izveidot jaunu neradniecîgu pâri. Pçc divu gadu pârtraukuma ðogad atkal sekmîgi vairojâs melnie stâríi Ciconia nigra. Tika izdçtas trîs olas, un izðíîlâs un sekmîgi izauga visi trîs mazuïi. Esam nâkuði pie secinâjuma, ka nebrîvç nelielâ aplokâ melnie stâríi nevairojas, ja aplokâ ir vçl kâdi putni (mûsu gadîjumâ tâs bija rudâs pîles Tadorna ferruginea 2005. gadâ) un ja tiek mainîta ligzdas apkârtne (putnu gripas profilaksei pâr voljeru pârvilktais tîkls un tents 2006. gadâ). Ornitoloìijas nodaïâ vienmçr tiek veicinâta Sarkankakla zoss Branta ruficollis ar mazuli. Red-breasted goose with young. Lielâ pûkpîle Somateria mollissima ar mazuli. Common eider with young. Rudo diþpîïu Tadorna ferruginea mazuïi. Ruddy shelduck young. Paradîzes dzçrvju Anthropoides paradisaea pâris. Stanley crane pair.
