Incazelo yesilwane

I-shrew evamile iyilungu lomndeni wakwa-shrew, ovame kakhulu emazweni amaningi. Uyilungu elikhulu lomndeni.

shrew yokuphila

Udlani umkhovu

Lezi zilwane ezincelisayo ezincane ziyizilwane ezidla ezinye. Bachitha isikhathi sabo esiningi befuna ukudla. Ukuzizwa njalo kwendlala esilwaneni kungenxa ye-metabolism esheshayo kakhulu.

Ngesikhathi sasehlobo Ukudla okuyinhloko kwama-shrews yizi:

Ebusika, ukudla kwesilwane kuqukethe izinambuzane ezihlala ebusika ezindaweni ezingaphezulu zenhlabathi. Uma sesiku-pantries kanye ne-cellars, isilwane asichithi isitokwe sokudla, kodwa sibheka kuphela izinambuzane ezihlala ebusika.

Lezi zilwane ezincelisayo azivamile ukudla ukudla kwezitshalo. Kuphela ngenkathi ebandayo ama-shrews angakwazi ukwengeza ukudla kwawo okuncane ngamantongomane noma imbewu evela ku-spruce nama-pine cones.

ukuzalanisa ama-shrew

I-shrew encane.

I-shrew yesifazane iletha inzalo izikhathi ezingu-2-3 ngonyaka. Enzalweni eyodwa, amawundlu angu-7-8 ngokuvamile avela. Isikhathi sokukhulelwa kwesilwane yizinsuku ezingu-18-28. Izilwane zizalwa ziyizimpumputhe futhi zinqunu, kodwa kakade ezinsukwini ezingu-30 emva kokuzalwa ziyakwazi ukuzimela ngokuzitholela ukudla kwazo.

• encane noma i-Chersky, ummeleli omncane kunabo bonke kuze kufike ku-4 amagremu;
• I-Tibetan, efana nejwayelekile, kodwa ehlala ezindaweni zezintaba;
• I-Bukhara, isilwane sase-alpine esinombala onsundu ngokukhanyayo esinebhulashi emsileni;

isiphetho

Ngokuvamile, ama-shrews adidaniswa nabameleli bomndeni wegundane futhi zonke izono zabo zibhekwa kubo. Nokho, lezi zilwane azizona nhlobo izinambuzane ezinonya futhi, ngokuphambene nalokho, zisiza ukuvikela isivuno ezinambuzaneni eziyingozi.
