Kodi akadzidzi a chipale chofewa amawoneka bwanji?
Akadzidzi a chipale chofewa ndi a m'banja la kadzidzi ndipo ndi achibale apamtima a mphungu. Ndi mbalame zamphamvu kwambiri: zimatha kukula mpaka 66 centimita ndikulemera mpaka 2.5 kilogalamu. Kutalika kwa mapiko awo ndi 140 mpaka 165 centimita.
Akazi ndi aakulu kwambiri kuposa amuna. Amuna ndi akazi amasiyananso pa maonekedwe a nthenga zawo: pamene amuna amayera ndi kuyera m’kati mwa moyo wawo wonse, akadzidzi aakazi a chipale chofeŵa amakhala ndi nthenga zowala zokhala ndi mizere yofiirira. Little Snowy Owls ndi imvi. Chitsanzo cha kadzidzi ndi mutu wozungulira wokhala ndi maso akulu, achikasu agolide ndi mlomo wakuda.
Ngakhale mlomo uli ndi nthenga – koma n’ting’onoting’ono kwambiri moti munthu sangauone patali. Makutu a kadzidzi a chipale chofewa samveka bwino motero samawoneka bwino. Akadzidzi amatha kutembenuza mitu yawo mpaka madigiri 270. Iyi ndi njira yabwino kwambiri yoti aziyang'anira nyama.
Kodi akadzidzi a chipale chofewa amakhala kuti?
Akadzidzi a Snowy amakhala kumpoto kwa dziko lapansi: kumpoto kwa Ulaya, Iceland, Canada, Alaska, Siberia, ndi Greenland. Amangokhala kumeneko kumpoto kwenikweni, pafupi ndi Arctic Circle.
Dera lawo lakumwera kwambiri lomwe amagawirako lili kumapiri a Norway. Komabe, sizipezeka pachilumba cha Arctic cha Svalbard, chifukwa kulibe ma lemmings kumeneko - ndipo ma lemmings ndi nyama zomwe zimadya kwambiri. Akadzidzi a chipale chofewa amakhala pa tundra pamwamba pa mtengo pomwe pali bog. M’nyengo yozizira amakonda madera kumene mphepo imawomba chipale chofewa. Kuti abereke, amapita kumadera kumene chipale chofewa chimasungunuka mwamsanga m'nyengo ya masika. Amakhala m'malo okwera kuchokera kunyanja mpaka 1500 metres.
Kodi pali akadzidzi amtundu wanji?
Mwa mitundu pafupifupi 200 ya akadzidzi padziko lonse lapansi, 13 yokha imakhala ku Europe. Kadzidzi, yemwe ndi wosowa kwambiri m'dziko lino, amafanana kwambiri ndi kadzidzi wa chipale chofewa. Koma adzakhala wamkulu kwambiri. Kadzidzi ndi mtundu waukulu kwambiri wa akadzidzi padziko lapansi. Kutalika kwa mapiko ake kumatha kufika masentimita 170.
Kodi akadzidzi a chipale chofewa amakhala ndi zaka zingati?
Akadzidzi akutchire amakhala pakati pa zaka zisanu ndi zinayi ndi 15. Koma ali mu ukapolo, amakhala ndi moyo mpaka zaka 28.

Kodi akadzidzi a chipale chofewa amakhala bwanji?
Akadzidzi a chipale chofewa ndi oyendayenda. Malo awo okhala ndi ochepa kwambiri kotero kuti nyama zawo zikucheperachepera. Kenako kadzidzi wa chipale chofewa amapita chakummwera mpaka kukapezanso chakudya chokwanira.
Mwa njira imeneyi, kadzidzi wa chipale chofewa nthawi zina amapezeka ngakhale pakati pa Russia, pakati pa Asia, ndi kumpoto kwa United States. Ngakhale kuti akadzidzi a chipale chofewa amakonda kukhala achangu madzulo, amasaka nyama masana ndi usiku. Izi zimatengera nthawi yomwe nyama yawo yayikulu, ma lemmings ndi grouse, akugwira ntchito.
Akamalera ana, nthawi zambiri amapita kukapeza chakudya chokwanira. Akaleredwa, amakhala osungulumwa kachiwiri ndikuyendayenda okha m'dera lawo, lomwe amawateteza kuzinthu zodziwika bwino. Pokhapokha m'nyengo yozizira kwambiri pamene nthawi zina amapanga ming'oma yotayirira. Akadzidzi a chipale chofewa amatha kupirira ngakhale nyengo yovuta kwambiri: Nthawi zambiri amakhala osasunthika pamiyala kapena m'mapiri kwa maola ambiri ndikuyang'ana nyama.
Izi zimatheka chifukwa thupi lonse, kuphatikizapo mapazi, ali ndi nthenga – ndipo nthenga za kadzidzi wa chipale chofewa zimakhala zazitali komanso zonenepa kuposa za kadzidzi wina aliyense. Atakulungidwa motere, amatetezedwa mokwanira ku chimfine. Kuphatikiza apo, akadzidzi a chipale chofewa amatha kusunga mafuta okwana magalamu 800, omwe kuwonjezera pa nthengazo amateteza kuzizira. Chifukwa cha mafuta osanjikizawa, amatha kupulumuka nthawi yanjala.
Anzanu ndi adani a kadzidzi
Nkhandwe za ku Arctic ndi skuas ndi adani okha a kadzidzi. Zikaopsezedwa, zimatsegula milomo yawo, kugwedeza nthenga, kukweza mapiko awo ndi kuimba mluzu. Woukirayo akapanda kuchoka, amadziteteza ndi zikhadabo ndi milomo kapena amakankhira adani awo pothawa.
Kodi akadzidzi a chipale chofewa amaberekana bwanji?
Nyengo yokwerera kadzidzi wachisanu imayamba m'nyengo yozizira. Amuna ndi akazi amakhala limodzi nyengo imodzi ndipo amakhala ndi okondedwa m'modzi panthawiyi. Amuna amakopa zazikazi ndi kuyimba komanso kukanda mayendedwe. Izi zikusonyeza kukumba dzenje la chisa.
Kenako yamphongo imapanga maulendo apaulendo, omwe amakhala pang'onopang'ono komanso pang'onopang'ono mpaka amagwera pansi - ndikubwereranso mlengalenga. Mbalame zonse ziwirizi zimayimba ndipo yaimuna imakokera yaikazi kumalo oyenera kuswana. Mwamunayo amanyamula mutu wakufa m'kamwa mwake. Pokhapokha ikadutsa kwa yaikazi m'pamene kukweretsa.
Kuswana kumachitika pakati pa miyala ndi mapiri kuyambira pakati pa Meyi. Yaikazi imakumba dzenje n’kuikiramo mazira ake. Malinga ndi kapezedwe ka chakudya, yaikazi imaikira mazira atatu kapena khumi ndi limodzi pakadutsa masiku awiri. Imakwirira yokha ndipo imadyetsedwa ndi yaimuna panthawiyi.
Patapita pafupifupi mwezi umodzi, anawo amaswa, nawonso pakadutsa masiku awiri. Choncho anapiye ndi amisinkhu yosiyana. Ngati chakudya sichikwanira, anapiye aang’ono kwambiri amafa. Pokhapokha ndi chakudya chochuluka m’pamene aliyense adzapulumuka. Yaikazi imayang’anira ana m’chisa pamene yaimuna ikukatenga chakudya. Mwanayo amathamanga pambuyo pa masabata asanu ndi limodzi kapena asanu ndi awiri. Amakhala okhwima pakugonana kumapeto kwa chaka chachiwiri cha moyo.
Kodi akadzidzi a chipale chofewa amasaka bwanji?
Akadzidzi a chipale chofewa amauluka pafupifupi mwakachetechete m’mlengalenga ndipo amadabwa nyama yawo, imene imaigwira pouluka ndi zikhadabo zawo n’kuzipha ndi milomo yawo yakuthwa yosongoka. Mukapanda kuwagwira koyamba, amathamangira nyama zawo, akugubuduza pansi. Chifukwa cha nthenga za mapazi awo, iwo samamira mu chipale chofeŵa.
Kodi akadzidzi a chipale chofewa amalankhulana bwanji?
Akadzidzi a chipale chofewa ndi mbalame zamanyazi komanso zabata kwambiri kwa chaka chonse. Amuna amangotulutsa squawk mokweza komanso mozama, "Hu" panyengo yokweretsa. Kuyimba kumeneku kumamveka kutali. Kung'ung'udza kowala komanso kwachete kumamveka kuchokera kwa akazi. Komanso, akadzidzi a chipale chofewa amatha kulira ndi kuchenjeza kulira kwa mbalamezi.
