Kumene amphamba amphongo amapanga nyumba zawo
Zilombozi zimasuntha pang'ono. Mbalame zomwe zimaswana kumadera ozizira ozizira zimasamukira kumadera otentha, zina zimayenda maulendo ataliatali kuti zikafike ndikubwezera malo okhala zisa.
Herons makamaka amakhala pafupi ndi malo okhala madzi oyera monga mitsinje, nyanja, mayiwe, malo osungira ndi madambo, mchere kapena malo obisalirako madzi.
Kufotokozera kwa imvi heron
Mbalame zamphongo ndi mbalame zazikulu, zomwe ndizitali masentimita 84 mpaka 102, kuphatikizapo khosi lokhalitsa, mapiko a 155 - 195 cm ndi kulemera kwa 1.1 mpaka 2.1 kg. Nthenga zakumtunda ndizambiri zotuwa kumbuyo, mapiko ndi khosi. Nthenga zomwe zili kumunsi kwa thupi ndi zoyera.
Mutuwu ndi woyera ndi "nsidze" yakuda komanso nthenga zakuda zazitali zomwe zimamera kuchokera kumaso mpaka koyambirira kwa khosi, ndikupanga khungu. Wamlimba wolimba, wonga lupanga ndi miyendo yachikaso mwa achikulire osaswana, otembenuka-ofiira ofiira nthawi yokolola.
Amawuluka potambasula makosi awo atali (ooneka ngati S). Mbali yapadera ndi mapiko otambalala ndi miyendo yayitali ikulendewera mlengalenga. Zitsamba zam'madzi zimauluka pang'onopang'ono.
Kodi azungu amamadyetsa chiyani?
Mbalame zimadya nsomba, achule ndi tizilombo, zokwawa, nyama zazing'ono komanso mbalame.
Zilombo zakuda zimakonda kusaka m'madzi osaya, kuima osasunthika m'madzi kapena pafupi nawo, kudikirira nyama, kapena kuwatsata pang'onopang'ono kenako ndikumenya nawo mlomo wawo. Wovutitsidwayo amezedwa kwathunthu.
Nkhandwe imvi idagwira chule wamkulu
Nesting herons imvi
Zitsamba zakuda zimamera limodzi kapena m'midzi. Zisa zimamangidwa m'mitengo pafupi ndi madzi m'mphepete mwa nyanja kapena m'mabango. Herons ndi okhulupilika kumalo awo oberekera, amabwerera kwa iwo chaka ndi chaka, kuphatikizapo mibadwo yotsatira.
Kumayambiriro kwa nyengo yoswana, amuna amasankha malo okhala ndi zisa. Maanja amakhala limodzi nthawi yonse yokwatirana. Ntchito yobereketsa imawonedwa kuyambira February mpaka koyambirira kwa Juni.
Zisa zazikulu papulatifomu zimamangidwa ndi ntchentche kuchokera ku nthambi, timitengo, udzu ndi zinthu zina zomwe amuna amasonkhanitsa. Zisa nthawi zina zimafika mita imodzi m'mimba mwake. Zitsamba zakuda zimakhazikika mu korona wa mitengo yayitali, m'nkhalango zowirira ndipo nthawi zina pamtunda wopanda kanthu. Zisa izi zimagwiritsidwanso ntchito munyengo zotsatira kapena zisa zatsopano zimamangidwa pazisa zakale. Kukula kwa chisa kumakopa akazi, amakonda zisa zazikulu, amuna mwamphamvu amateteza zisa zawo.
Zazimayi zimayikira limodzi kapena mazira 10 pachisa. Chiwerengerocho chimadalira momwe zinthu zilili zabwino polera nyama zazing'ono. Zisa zambiri zimakhala ndi mazira obiriwira abuluu 4 mpaka 5. Makolo amasinthanasinthana kukhalira mazira kwa masiku 25 kapena 26 anapiye asanatuluke.
Anapiye a nyerere akuda
Ana amatsekedwa pansi, ndipo makolo onse amawasamalira, kuteteza ndi kudyetsa nsomba zomwe zayambirazo. Kuwomba mokweza kwa anjala anjala kumamveka masana. Poyamba, makolowo amadyetsa, akubwezeretsanso chakudya pamlomo, kenako kenako kupita ku chisa, ndipo anapiye amapikisana nawo kuti adye nyamayo. Amakankhira okondedwa awo kunja kwa chisa ngakhale kudya abale ndi alongo omwe anafa.
Anapiye amasiya chisa pakatha masiku 50, koma amakhala pafupi ndi makolo awo mpaka akadzakwanitsa kudzidalira pakatha milungu ingapo.
Kodi nkhandwe zaimvi zimakhala zazitali bwanji?
Mbalame yayikulu kwambiri idakhala zaka 23. Nthawi yayitali yazachilengedwe ndi pafupifupi zaka 5. Pafupifupi gawo limodzi mwa magawo atatu aliwonse amakhala ndi moyo kufikira chaka chachiwiri chamoyo; atsitsi ambiri amtundu wawo amakhudzidwa.
