Indawo jay oluhlaza okwesibhakabhaka (ICyanocitta cristata) sisuka empumalanga ye-United States naseningizimu yeCanada siye eGulf of Mexico. Izinyoni eziningi ezihlala enyakatho yebanga zifudukela eningizimu ebusika. Indiza yenzeka phakathi nesikhathi semini emhlanjini wezinyoni ezingama-5-50 noma ngaphezulu (imihlambi enezinyoni ezingafinyelela ku-3,000 yabonwa). Ama-jay aluhlaza okwesibhakabhaka ahlala ezinhlobonhlobo zezindawo zokuhlala - amahlathi ahlukanisayo, amapaki nezingadi, izindawo zokuhlala zezigodi ezingaphansi komhlaba. Kepha nokho bakhetha ihlathi le-oki elixubile nele-beech, kepha-ke, entshonalanga yebanga bangatholakala emahlathini aphayiniwe awomile nezihlahlana.

Incazelo

Ubude bomzimba walezi zinyoni ezinhle bufika ku-30 ​​cm, amaphiko acishe abe ngu-42 cm, isisindo sisuka ku-70 kuye ku-100 g.Ijay eluhlaza okwesibhakabhaka inemuva oluhlaza okwesibhakabhaka, umgexo omude ohlaza okwesibhakabhaka, umgexo omnyama, iphethini eluhlaza okwesibhakabhaka nomhlophe emaphikweni futhi emnyama nomhlophe umsila onemigqa emhlophe. Abesilisa nabesilisa banemibala efanayo, kepha abesilisa bakhulu. Uqhwaku lwazo luqinile, ngenxa yokuthi ama jay angaqhekeza kalula imbewu enzelwe kanzima. Lezi zinyoni zingenza imisindo ehlukahlukene kakhulu, ngokwesibonelo, ikhwela lomsindo kanye nemisindo efana nokukhala kwensimbi, balingisa ukukhala kosokisi, bamemeze kakhulu, bexwayisa ngokusondela komphangi, lo mbhangqwana, ukhulumisana omunye nomunye, wenza umsindo ofana nephampu yokugqwala. Kwesinye isikhathi ama-jay alingisa ama-hawks ukukhohlisa ezinye izinyoni futhi azixoshe kude nokudla. Bangabalingisi abahle kakhulu, ekuthunjweni bafunda ngokushesha ukulingisa ukukhuluma kwabantu.

Umsoco nokuziphatha kahle

Ama-jay aluhlaza okwesibhakabhaka - izinyoni zenhlalo, zigcinwa ngababili, amaqembu amancane omndeni noma amaphakethe. Ama-jays aqabile, ukudla kwabo kufaka phakathi imifino (ama-acorns, amantongomane we-beech, imbewu nezithelo, amajikijolo - kuze kube ngu-78%), kanye nokudla kwezilwane (amabhungane, izintethe, izicabucabu, amazimila, izibungu, ama-vertebrates amancane - amachwane namaqanda, izibankwa namaqanda amasele, amagundane - afinyelela kuma-22%), kanye ne-carrion. Ama-jay aluhlaza okwesibhakabhaka ajwayele ukuthatha inyamazane kwezinye izinyoni. Abantu abangafuduki benzela ukubekelela ubusika, ngokwesibonelo, ama-acorns kanye nembewu kufihlwe emifantweni yegxolo noma ngaphansi kwamaqabunga awile, angcwatshwa emhlabathini. I-jay eyodwa ngesikhathi sokuwa "ingalungiselela" ukufika kuma-acorn ayizinkulungwane ezingama-3-5. Ngesinye isikhathi, le nyoni ithwala ama-acorn angaba mahlanu - isonga ama-acorn angama-2 000 kuyi-goiter, enye ibambe emlonyeni kanti omunye ngomlomo wayo.

I-Nesting

Ama-jay aluhlaza okwesibhakabhaka ama-monogams akha amaphenyana njalo (kwesinye isikhathi ngokuphila.) Ngokuvamile, izidleke zalezi zinyoni eziwu-18-20 cm ubukhulu zitholakala kumfoloko wamagatsha asezingeni lezihlahla ezi-deciduous noma ezi-coniferous endaweni ephakeme ngamamitha ama-8-10. Izinduku ezisetshenziselwa ingaphandle lesidleke ziphulwa izinyoni ezihlahleni eziphila. Izimpande ezahlukahlukene ezivumelanisa isidleke, ama jay aqoqwa emgodini osanda kubekwa, amathuna amasha emathuna, ezihlahleni ezisanda kuwa, njll. Konke lokhu kungabekwa ngokucophelela, futhi kwesinye isikhathi kufakwe ngomhlabathi omdaka noma ngodaka. Ugqoko wesidleke ufakwe emgqonyeni wezintambo, uvolo, umhlwa, iphepha, amacembe omile notshani. Ngaphambi kokuqeda ukwakha isidleke, izinyoni zakha izidleke eziningana ezingapheleli - lokhu kuyingxenye yesiko lokuqomisana. Ukondla insikazi nakho kuyingxenye yalesi siko - sekushayele phezulu kowesilisa esihlahleni esingumakhelwane, lowesifazana uthatha indawo yenkukhu ecela ukudla bese owesilisa eyondla. Uma isidleke sitholwa umdlwenguli, izinyoni zingashiya unomphela.

Esikhathini sokuzalela, ama-jay akhuluma athula kakhulu.

15.07.2015

I-Blue Jay (Latin Ceanocitta cristyata) iyinyoni ebukeka kahle kakhulu evela emndenini wakwaCorvidae we-Passeriformes woku-oda. UMark Twain wake waveza ukuthi ama-jay abizwa ngokuthi izinyoni kuphela ngoba anezimpaphe futhi awayi esontweni. Ngaphandle kwalokho, benza izinto ezifanayo nabantu. Bafunga, ngobuqili futhi baqamba amanga ngaso sonke isikhathi.

Ukuziphatha

IBlue Jay idume ngokuthi inomsindo omubi. Uyaziwa ngesikena sakhe sokubhoboza kanye nekhono lakhe lokulingisa ukukhala okukhulu kokhonkolo. Le nyoni ihlala isebenzisa lokhu ukuxosha izimbangi kusuka ku-feeder. Lobuqili abusebenzi isikhathi eside. Imvamisa, ngemuva kwesikhashana, izinyoni ezikhohlisiwe ziyabuya.

Kwesinye isikhathi i-jay ijabulisa abanye ngengoma ethambile nethule noma ukulingisa imisindo yezinyoni zezingoma. Naphezu kwamapheya ayo akhanyayo, izifihla kalula emagatsheni ezihlahla, noma ngabe yonke into ezungeze imbozwe yiqhwa. abamele le nhlobo balingisi abakhulu.

Njengoba besekudingisweni, balingisa kalula ukukhuluma kwabantu.

Ama-jay okuxhumana nomunye kwenzeka ngosizo lwe-crest. Ngesikhathi sokujabula noma ukungena kwemizwa engemihle, i-crest ikhuphuka ibheke phezulu. Kwinyoni emangele, iqondiswa phambili, futhi endaweni eshaywayo ethukile, ifana nebhulashi elihlotshisiwe lokuhlanza amabhodlela.

Indawo yokuhlala yama-jay aluhlaza okwesibhakabhaka itholakala kulo lonke ugu lwaseNyakatho Melika. Njengomthetho, bahlala emhlambini omncane. I-jay ingeyenyoni efudukayo ngokwengxenye, ngoba kuphela abantu basenyakatho abaya kuhambo oluseningizimu. Umhlambi wabantu aba-5 kuye kwabayi-3 000 uzodiza phakathi nosuku. Ebusika, zivame ukundiza ezindaweni ezinamadolobhana, amapaki namapulazi.

Ukudla kwama-jay aluhlaza okwesibhakabhaka kuqukethe amantongomane ahlukahlukene, imbewu, izinambuzane, amajikijolo nezilwane ezincane. Uvame ukucekela phansi izidleke zabanye abantu. Le nyoni yenza ukubekelela ubusika emigodini yezihlahla ezindala, emihumeni ephakathi kwamagxolo, igaya imbewu ibe ngamaqabunga awile futhi, ngakho-ke, ikhuthaza ukwenziwa kabusha kwezihlahla nezihlahla. Angakwazi ukufihla afike kuma-acorns angama-5,000 ngosuku. Ngesinye isikhathi, le nyoni ithwala ama-acorn angaba mahlanu ngomlomo wayo.

IBlue Jay ihlukaniswa ubuhlakani nokukhohlisa. Ngokubona ingozi, ngokushesha uqala ukukhipha ukukhala, axwayise zonke izinyoni nezilwane eziseduze. Lapho umhlaseli evela, izinyoni zihlangana emhlanjini bese ziyawuhlasela.

Ukuzala

UBlue Jay ukhetha umuntu azoshada naye impilo yakhe yonke. Abalingani bayaxhumana besebenzisa imisindo ekhumbuza iphampu yokugqwala. Izinyoni zakha isidleke esicocekile emagatsheni esihlahla noma esihlahleni ukuphakama kwamamitha amathathu kuya kwayishumi. Bayakha kusuka emagatsheni amasha aphukile.

Ngaphansi kwesidleke kufakwe izimpande. Konke lokhu kubekwa ngokuzwakalayo, futhi kwesinye isikhathi kufakwe ngodaka olumanzi. Ukondla insikazi luhlobo lwamasiko. Ngemuva kokuthatha itshe lengane ecela ukudla, insikazi ilinda owesilisa ukuba ayondle.

Owesifazane ubandakanyeka ekuqathulweni kwamachwane. Kabili ngonyaka, ubekela amaqanda ngenani lezicucu ezintathu kuya kweziyisithupha. Uma kwenzeka ukuthi inyamazane ithole isidleke, izinyoni ziyishiya kuze kube phakade.

Kwenye i-clutch kunamaqanda afinyelela kwayi-7 wombala oluhlaza-ophuzi noma oluhlaza okwesibhakabhaka onamabala amnyama. Ngemuva kwezinsuku eziyi-8, kuzalwa amachwane.

Bobabili abazali bondla futhi banakekele izingane. Bahlanza izimpaphe zabo, bazifudumeze futhi bazivikele engozini.

Ngemuva kwezinsuku ezi-5, amehlo amachwane ayavuleka, kuthi emva kwesonto iplamu liqale ukukhula. Izinsuku ezimbalwa ngaphambi kwendiza yokuqala, izingane ziqala ukuphuma esidlekeni zihamba ngamagatsha esihlahla. Abahambi kude nalo ngaphezu kwamamitha ayi-5. Ezinsukwini ezingama-20 emva kokuzalwa kwazo, amaphuphu asevele azi ukuthi angandiza kanjani, kepha kepha awandiza esidlekeni sawo ngamamitha angaphezu kwama-20. Kukho konke ekwindla, izingane zihlala eduze nabazali bazo, bese kuthi ebusika zizimele.

Ukuncibilika kokuqala kwentsha kwenzeka ekupheleni kuka-Agasti. Izinyoni zabantu abadala ziqala ukuncibilika ngoJulayi bese ziphela ngoSepthemba. Ngenkathi yokuncibilikisa, ama-jay athatha ukugeza kwezintuthwane, kwesinye isikhathi efaka izinambuzane ngaphansi kwezimpaphe zazo.

Kulula ukwahlukanisa i-jay eluhlaza okwesibhakabhaka kwezinye izinyoni ngomsila wayo onemibala emnyama nomhlophe, emuva okwesibhakabhaka, isigubhu esifushane esiluhlaza okwesibhakabhaka esisemaphikweni aso, umgexo ozungeze intamo yakhe nephethini emnyama nomhlophe neluhlaza okwesibhakabhaka. Inyoni encane inesisindo esingama-gramu ayi-100. Ubude bomzimba abudluli ku-30 ​​cm, kuthi amaphiko afinyelele ku-40 cm.

Isikhathi sokuphila se-jay eluhlaza okwesibhakabhaka, ngokuya ngezimo zemvelo, sisukela eminyakeni eyi-10 kuye kweli-18.

INyakatho Melika Jay Indlela Yokuphila

Ama-jay aluhlaza okwesibhakabhaka ayizinyoni ezihlakaniphile futhi ezinobuqili.

Uma i-jay ibona ingozi, ikhala kakhulu, ibika usongo kwezinye izinyoni nezilwane. AmaJay ajwayele ukujoyina amaqembu futhi ahlasele izinyamazane.

AmaJay ahlala ezingxenyeni ezisenyakatho yebanga athuthela eningizimu, kepha abanye abantu bangahlala endaweni yasebusika. AmaJay andiza phakathi nesikhathi semini. Bahamba phakathi kwabantu abangama-5-50, kepha kwesinye isikhathi babuthana emhlambini omkhulu - cishe izinyoni ezingama-300.

Ama-jay aluhlaza okwesibhakabhaka ahlala ngababili noma ngamaqembu amancane emindeni.

I-molt yokuqala yezinyoni ezincane yenzeka ngasekupheleni kwehlobo, kuthi ama-jay amadala aqhume ngoJulayi kuya kuSepthemba. Ngenkathi yokuncibilikisa, ama-jays ajwayele ukugeza kuma-anthill futhi athole lezi zinambuzane ngaphansi kwamaphiko awo. Kukholelwa ukuthi ama-jay ngosizo lwezintuthwane ziluma isikhumba salo esimnandi ngokukhula kwezimpaphe.

Ama-Jinji ahlanganisiwe ayizinyoni zomphakathi impela.

Ama-jay aluhlaza okwesibhakabhaka ahlala emaqenjini emindeni, ngababili, noma emihlanjini emincane. Baxhumana bodwa besebenzisa ulimi lomzimba, ngoba lokhu basebenzisa ama-crests. Uma i-jay ikhathazeka noma isesimweni sokufuthelana, khona-ke i-crest iba mpo, lapho kumangala, i-crest iqhubekela phambili, uma kwenzeka ngokwesaba, i-crest eduzane ne-jay ifana ne-brashi.

Ama-jay aluhlaza okwesibhakabhaka ahola indlela yokuphila yokuphila komuntu oyedwa.

Ama-jay aluhlaza okwesibhakabhaka enza inqwaba yemisindo: ukulingisa ukukhala kokhozi, ukukhala njengezinsimbi, ukushaya ikhwela ngomsindo, ukukhala kakhulu, ukuxwayisa ngengozi, abamele lo mbhangqwana baxhumana phakathi kwabo nemisindo ekhalayo. AmaJay abalingisi abahle kakhulu; ekudingisweni bangaqeqeshwa kalula ukulingisa ukukhuluma kwabantu.

Izitha zabakholwayo zidalwa yizikhova namanga. Isikhathi sokuphila kwabo ngokwemvelo yiminyaka eyi-10-18.

I-Blue Jay Nutrition

Ama-jay aluhlaza okwesibhakabhaka ayizinyoni ezinhle kakhulu. Bangadla ukudla kwezitshalo, njengamantongomane we-beech, ama-acorns, amajikijolo, imbewu, izithelo, nokudla kwezilwane: izintethe, izicabucabu, amabhungane, umiyela, amasele, izibungu, amachwane, amagundane, amaqanda enyoni. Ngaphezu kwalokho, isidumbu singadliwa.

IBlue Jay inyoni ehlakaniphile, enobuqili futhi ekhohlisayo.

I-jay ngayinye ngesikhathi sokuwa ingathenga ama-acorn ayizinkulungwane ezingama-3-5.

Ukudla kwezitshalo kubiza ama-78% ekudleni okuluhlaza okwesibhakabhaka, kuthi ama-22% izinambuzane nezimpawu ezincane zomlomo omncane. AmaJay ajwayele ukuntshontsha inyamazane kwezinye izinyoni. Ama-jay angagudluki okugcinwa kuwo amasheya wasebusika, ngokwesibonelo, aqoqa imbewu, ama-acorn futhi awafihla ngaphansi kwamagxolo ezihlahla noma azingcwabele ngamahlamvu kanye nenhlabathi. I-jay ingathwala ama-acorn angama-5 ngesikhathi: I-1 ibamba ngomlomo wayo, umlomo om-1 omningi no-2-3 ku-goiter.

Abancintisana ngokudla kwama jay asetshenzisiwe bangama-Woodpeckers, izihlahlana, ama-jay aseFlorida, ama-squirrel ama-grey, kanye nama-starlings. AmaJay kwesinye isikhathi alingisa ama-hawks ukushayela ezinye izinyoni kude nokudla, kepha izinyoni eziningi zivame ukubuya masisha lapho nje ama-jay eqala ukudla.

Izinzuzo kanye nokulimala kwama-jay aluhlaza okwesibhakabhaka kubantu

AmaJay aqothula izinambuzane eziyingozi, ngokwesibonelo, izinambuzane zasehlathini ezinjengamabhungane e-barbel, amabhungane kaMeyi, amacimbi, izibungu nokunye. Ama-jay aluhlaza okwesibhakabhaka adotshwa kalula futhi anezimpande ngokuphelele ekuthunjweni. Kepha lezi zinyoni zinolaka, ngakho-ke azikwazi ukugcinwa kanye nezinye izinyoni.

Blue Blue kuyinto emnivorous.

AmaJuvu amaTufted yi-talisman yamaqembu amaningi ezemidlalo, kukhona neqembu le-basketball laseToronto Blue Jays eliqeqeshiwe. Unyaka nonyaka, ama-jay aqeda inqwaba yezidleke zezinyoni ezincane; abulala amachwane adle amaqanda. Kodwa bayazuza ngokusakaza ama-acorns kanye nembewu.

Blue jelly labantu

AmaJay anele ngokwanele kulo lonke uhla. Namuhla kunama-subspecies ama-4 ama-jay aluhlaza okwesibhakabhaka:

• C. c. i-cyanotephra ijwayelekile eNebraska, eWyoming, eKansas, eColorado, eTexas nase-Oklahoma,
• C. c. ama-bromia ahlala eNewfoundland, North Dakota, North Canada, USA, Missouri nase Nebraska,
• C. c. ama-semplei atholakala enyakatho neFlorida,
• C. c. I-cristata itholakala eKentucky, eMissouri, eVirginia, eTennessee, e-Illinois, eFlorida, eTexas naseNyakatho neNorth Carolina.

Uma uthola iphutha, sicela ukhethe ucezu lombhalo bese ucindezela I-Ctrl + Faka.

Ukubukeka

Ngokwamandla okuthiwa yi-dimorphism yezocansi, abesilisa ngokwemvelo bakhulu kunabesifazane, kepha umehluko phakathi kobulili awusebenzi kumbala - ubukhulu bezinsikazi nabesilisa buhlotshaniswa ngombala ohlaza okwesibhakabhaka.

Kuyathakazelisa! Labo ababephethe i-jay ezandleni zabo bathi umbala oluhlaza okwesibhakabhaka umane nje kuwukukhohlisa okubonakalayo. Kukhanya kubuye kukhishwe ekwakhekeni kwangaphakathi kwezimpaphe, kubanikeze ukukhanya okuluhlaza okwesibhakabhaka okunyamalala ngokushesha lapho impaphe iphuma.

Ama-jay aluhlaza okwesibhakabhaka amadala akhula afinyelela kuma-25-29 cm (anomsila olingana no-11-13 cm) ngaphandle kokuelula ngaphezu kuka-70-100 g.Amaphiko we-jay eluhlaza okwesibhakabhaka asondela ngamasentimitha angama-34-43. I-crest kungenzeka ukuthi iluhlaza okwesibhakabhaka noma i-violet-eluhlaza okwesibhakabhaka. Izimpaphe ngaphansi kwe-crest yepende emnyama. I-frenulum, umlomo kanye nokushaya kwendandatho eduze kwamehlo kudwetshwe ngombala ofanayo. Umphimbo, izihlathi kanye nangaphansi komzimba kumhlophe ngokumpunga.

Imiphetho yomsila imhlophe, futhi amabala amhlophe akhanyayo ayabonakala emaphikweni / emsileni. Ijay yaseNyakatho Melika inomsila oluhlaza okwesibhakabhaka nezimpaphe ezindizayo, ezidonswa imivimbo emnyama eshintshashintshayo. Le nyoni inamehlo amnyama futhi acwebezelayo, ama-paw grey amnyama nomlomo oqinile, lapho iphula kalula imbewu eboshwe egobolondweni elinzima.

Lapho kuhlala khona

Indawo yokuhlala eNyakatho Melika. AmaJay ahlala cishe izwekazi lonke esuka eCanada aye eGulf of Mexico.

Izinyoni zithanda ama-deciduous mono- namahlathi axubile. Kodwa-ke, okubaluleke kakhulu kungukudla kwe-beech ne-oki. Kukhona abantu abakhetha izihlahlana ezomile zokuphila, kepha lokhu kuyaqabukela.

UJay ungenye yalezi zinyoni ezingasabi nhlobo abantu futhi zihlala eduze kwabantu, ezingadini nasemapaki.

Izici zokuphila nokuziphatha

Uma ubheka ama-jay okungenani isikhashana, ungadweba ama-analogies amaningi nabantu. Lezi zimvuthuluka ezinamahloni zinobuqili, zibubende, zikwazi ukudukisa futhi zikhohlise izihlobo ngisho nezitha.

AmaJay aphila impilo ekhuthele kakhulu, awakhi imibhangqwana kuphela, kodwa futhi ahlela emindenini enkulu, emihlambini nasemiphakathini.

Indlela enkulu yokuxhumana phakathi kwezihlobo i-crest. Uma izimpaphe zakhe ziqondiswe phambili, lokhu kusho ukuthi i-jay iyamangala. Lapho ethukuthele noma ejabule, usukuma aqede, futhi lapho ethukile, uyakhuphuka.

IBlue Jay inekhono elihle lokulingisa imisindo, kuyilapho uhla lwayo lungalinganiselwe. Uzobonisa izisekelo zesondo noma ukuncipha kwamabhuleki kahle njengobhontshisi wethilogremu.

IBlue Jay idonsa izimbangi zayo kude nendawo lapho bathola khona into emnandi. Wenza lokhu ngokulingisa ukukhala kukaklebe. Kuliqiniso, maduze ukukhwabanisa sekwembulwa.

Ama-jay aluhlaza okwesibhakabhaka anesiginali ekhethekile ebukeka sengathi ihlehlisile futhi iqonde. Uma inyoni iyishicilela, kusho ukuthi kunesitha eduzane. Kaningi, izinyoni zihlangana zihlasele isivakashi esingamenywanga kuqala.

Okudingayo

I-jay eluhlaza okwesibhakabhaka ezindabeni zokudla ayinazo ngokuphelele izimiso. Udla konke akutholayo. Ngokuzolile, inyoni ingadla ukudla kwesinye isidalwa esinemibala, futhi futhi ikwazi ukudla ngo-carrion.

Ukudla kwakhe kuqukethe ukudla kwezitshalo nezilwane ngesilinganiso esingama-70: 30. AmaJay angandizeli ezindaweni ezifudumele zobusika enza izinqolobane ngokuhlela izindawo zokuhlala ngamagxolo ezihlahla, utshani nomhlaba.

Umndeni kanye nezingane

Isikhathi sokukhwelana kuma-jay aluhlaza okwesibhakabhaka siqala ngezinsuku zokuqala zasentwasahlobo ezifudumele. Lapho nje imibhangqwana isisungule, kuthula ukuthula emahlathini lapho zihlala khona. Izinyoni ziziphatha ngokuzithoba, ukuze zinganiki isitha indawo yezidleke zazo.

Bobabili abesilisa nabesifazane basebenza ekwakhiweni kwale ndawo yokuhlala. Isidleke sitholakala emagatsheni aseceleni, endaweni ephakeme ngamamitha ayi-3-10 ukusuka phansi, sifana kakhulu nophondo. Ekwakhiweni kwayo, izinyoni zisebenzisa izinto ezihluke ngokuphelele, kusukela emagatsheni kuya ephepheni nasezinjeni.

Imininingwane ethakazelisa kakhulu yemidlalo yokuzalelana yama-blue jays iyondla. Insikazi ihlala esidlekeni futhi ifanekisela inkukhu elambile, owesilisa athole ukudla ayondle.

Inani lamaqanda elibekwe yijay eluhlaza okwesibhakabhaka liyahlukahluka kusuka kwezingu-2 kuye kwezingu-7. Isikhathi sokubopha siyizinsuku eziyi-18.Kodwa-ke, uma ijaha libona ukuthi ikhaya lakhe litholwe umdlwenguli, belizomshiya ngaphandle kokuzisola futhi ngeke liphinde libuyele lapha.

Izinsikazi ezihlafunayo azisizi ngalutho, ziyimpumputhe, izithulu futhi zihamba ze. Ngakho-ke, abazali akufanele nje babondle, kodwa futhi bahlanzekile futhi bazishise. Kuphela emva kwamasonto ambalwa, imvuthuluka izobona futhi imboze nge-plumage.

Umama unquma ukushiya isidleke sokudla kuphela ngosuku lwe-12 emva kokuzalwa kwamachwane. Ngaphambi kwalokho, ubaba uletha ukudla. Izingane zihlala nabazali bazo isikhathi esithile - kuze kube sekupheleni kwekwindla, yize zizimele ekuqaleni kwalokho.

Isimo esisemthethweni seBlue Jay

Ziningi lezi zinyoni endaweni yaseNyakatho Melika, azivikelekile ngokukhethekile nganoma iyiphi indlela; ayikho into ebasabisayo lapha kuze kube manje. Kepha isimo singashintsha nganoma yisiphi isikhathi.

Ubuhle be-jay eluhlaza okwesibhakabhaka buyakhohlisa. Ngemuva kokubukeka okuhle, akusona isidalwa esihle esinemibala efihlekile, kepha ungumuntu okhaliphileyo noqaphile okwaziyo ukukhohlisa nokukhaphela.

IBlue Jay ayihlukaniswa kuphela ngokubonakala kwayo okuvelele. Ubuye abe nethalente elimangalisayo lokuhlekisa. Mhlawumbe okuwukuphela kwento okungenakulingiswa yile nyoni enhle kangaka ukukhuluma kwabantu. Ngasikhathi sinye, uJay usebenzisa amathalente akhe ahlukile ngendlela eyinqayizivele kakhulu. Ususa izimbangi zakhe ngenhloso yokudla, futhi kwesinye isikhathi umane ahlekise. Ukubukeka uJay ubukeka emuhle: luhlaza okwesibhakabhaka [...]

Isimilo nendlela yokuphila

UMark Twain wake wahlekisa ngokuthi ama-jay aluhlaza okwesibhakabhaka abizwa ngokuthi izinyoni kuphela ngoba anenqwaba futhi awayi esontweni. Ngaphandle kwalokho, bafana ngokuqinile nabantu: nabo babuqili, bafunga futhi bakhohlisa ngazo zonke izindlela.

Kuyathakazelisa! I-jay eluhlaza okwesibhakabhaka ivame ukulingisa ukukhala okukhulu kukaphisi ngokushayela izimbangi zalo zokudla, kufaka phakathi amajusi aseFlorida shrub, ama-woodpeckers, ama-starlings kanye nama-squirrel ama-grey, avela ku-feed ehlathini. Kuliqiniso, lobu buqili abuhlali isikhathi eside: ngemuva kwesikhashana, omakhelwane bakhohlisiwe bayabuya.

Ama-jay ahlanganisiwe abe nokuphila komphakathi okusebenzayo, okungagcini lapho kwizinyunyana ezibhangqiwe. Ngaphezu kwalokho, izinyoni zakha amaqembu emindeni noma imihlambi emincane, ukuxhumana nomunye ngezwi noma ngolimi lomzimba, noma kunalokho, ngosizo lwe-crest yazo enhle. Izimpaphe ezinamandla, eziqondiswe phambili, zitshela ngokumangala noma injabulo, ngentukuthelo eqoqiwe - isikhundla sayo sibheke phezulu.

Ngokwesaba, i-crest ikhukhumeza njengebhulashi lokugeza izitsha. I-Blue Jay iyi-onomatopoeic engaphenduleki. Ebhokisini lakhe lokucula kunemisindo eminingi ebikade izwakala ngemvelo, kusukela emicimbini ethule kuze kube sethomeni lokugqwala.

I-jay iyakwazi ukushaya ikhwela, ukushwabula kumemeza (ukulingisa izinyoni ezidla inyama), ukulingisa izinsimbi ukukhala, ukukhala (ukuxwayisa ngengozi), ukukhonkotha, ukuchela noma ukuphuma kwegazi. I-jay etshalwe ekhejini ifunda ngokushesha ukukhiqiza ukukhuluma kwabantu. AmaJay awagcini nje ngokwazisa indlela yesitha sabo bonke abahlala emahlathini: imvamisa izinyoni ziyahlangana ukuyihlasela ngobuso obunobunye.

Kusukela ngoJulayi kuya kuSepthemba, ama-jt molt amadala aseNyakatho Melika; ezilwaneni ezincane, i-molt yokuqala ivela ngasekupheleni kwehlobo. Ngenkathi yokuncibilikisa, bona, njengabaningi abanemibala, bahlela inqubo ebizwa ngokuthi ukucola: geza i-anthill noma izintuthwane zezinto ngaphansi kwezimpaphe. Ngakho-ke izinyoni ziyasusa izimuncagazi. Ama-jay amaningi aluhlaza okwesibhakabhaka ahlala enyakatho yezinhlobo zezindiza andiza aye ebusika ezindaweni eziseningizimu. Kumabhanoyi enziwe njengenjwayelo ngaphambi kwemini, izinyoni ziqoqana ngamaqembu amakhulu (afinyelela ezinkulungwaneni ezintathu) kanye nemihlambi emincane (abantu abangama-5-50).

Habitat, indawo yokuhlala

Ama-jay aluhlaza okwesibhakabhaka ahlala cishe isigamu sezwekazi laseNyakatho Melika, ahlala ikakhulu ezindaweni ezisempumalanga ye-USA neCanada. Indawo ye-jay elahliwe, eqanjwe ezweni laseBlue Jay, ifinyelela eGulf of Mexico. ENtshonalanga Melika, izindawo ezihlala jay eziluhlaza okwesibhakabhaka zisondelene nobubanzi bezinhlobo ezihlobene, iSteller brown-brown blue jay.

Njengamanje, izingxenyana ezi-4 ze-jay eziqanjiwe zichazwa, zihlukaniswa, phakathi kwezinye izinto, yindawo esatshalaliswa kuyo:

• ICyanocitta cristata bromia - kuhlala iNewfoundland, Northern Canada, North Dakota, Missouri neNebraska,
• ICyanocitta cristata cyanotephra - kutholakala eNebraska, Kansas, Wyoming, eColorado, e-Oklahoma naseTexas,
• I-cyanocitta cristata cristata - uhlala eKentucky, eVirginia, eMissouri, eTennessee, North Carolina, eFlorida, e-Illinois naseTexas,
• ICyanocitta cristata semplei - uhlala ezifundeni ezisenyakatho zeFlorida.

Ijay yaseNyakatho Melika ithanda ukuhlala emahlathini aqobayo, evame ukuxutshwa (i-oki ne-beech), kepha kwesinye isikhathi, ikakhulukazi entshonalanga yebanga, ihlala ezihlahleni ezinde noma emahlathini omile omile. I-jay ayesabi umuntu futhi ngaphandle kokungabaza yenza izidleke ezindaweni zokuhlala, lapho kunezindawo zokupaka nezingadi. Izinyoni ezihlala enyakatho yebanga zikhulu ngosayizi kunezihlobo zazo "ezingaseningizimu".

I-Blue Jay Diet

Ukudla okungenamsoco kwamajay e-crested kukhombisa amandla ayo, ukuzikhukhumeza (kuthatha ukudla kwezinye izinyoni) kanye nokungabikho kwesinengiso (kudla i-carrion).

Ukudla kwama-jay aluhlaza okwesibhakabhaka kuqukethe zombili izitshalo (kufika ku-78%) nokudla kwezilwane (22%):

• ama-acorn namajikijolo

Isimo sabantu kanye nezinhlobo zezinhlobo

Ama-jay aseNyakatho Melika azuza ngokubulala izinambuzane zasehlathini (uMay bugs, weevils kanye namacimbi) nokusabalalisa imbewu / ama-acorn. Kepha ukulimala okuvela kulezi zinyoni kuyabonakala - minyaka yonke babhubhisa izidleke zezinyoni ezincane, bagoqa amaqanda abo futhi babulale namantshontsho.

Encwadini ebomvu ye-International Union for Conservation of Nature, i-jay eluhlaza okwesibhakabhaka ibhalwe "njengezinhlobo ezikhathazayo kunazo zonke," ngoba akukho lutho olusongela ngakho njengamanje.
