Maererano nerugwaro rwacho, mabheya anodya huni here kana kuti anongotema miti yokuvaka madhamu?
Context:Mabheya (genus Castor) zvikara zvikuru zvinogara mumvura zvinowanikwa muNorthern Hemisphere. Kune marudzi maviri aripo: beaver yokuNorth America (Castor canadensis) uye beaver yokuEurasia (C. fiber). Mabheya ndiwo makonzo makuru kwazvo aripo, pashure pemakapybaras, anorema makirogiramu anosvika 50. Dzine miviri yakasimba ine misoro mikuru, maoko marefu akafanana nechivezwa, mvere dzakasvibira kana kuti dzakasvibira, tsoka dzokumberi dzakafanana nemaoko, tsoka dzeshure dzine makumbo, uye miswe yakati sandara uye ine mbabvu. Mhando mbiri idzi dzinosiyana pakugadzirwa kwedehenya uye muswe uye ruvara rwevhudzi. Mabvi anogona kuwanikwa munzvimbo dzinoverengeka dzemvura yakachena, dzakadai senzizi, hova, madziva nemadhamu. Zvinodya miti, zvinodya matanda emiti, zvinomera zvemumvura, uswa nemiti.  Madzimai anovaka madhamu nedzimba achishandisa mapazi emiti, zvinomera, matombo uye madhaka; anodya miti kuti agadzire zvinhu. Madamu anoderedza kuyerera kwemvura, uye dzimba dzokugara dzinoshanda senzvimbo dzokuvanda. Zvivako zvavo zvinogadzira nzvimbo dzine mvura dzinoshandiswa nemamwe marudzi akawanda, uye nemhaka yemigumisiro yazvo pane zvimwe zvisikwa zviri muchimiro chemhoteredzo yezvinhu zvipenyu, mabheya anoonekwa semarudzi anokosha.
Mhashu dzinodya zvinomera uye dzinozivikanwa kuti dzinodya makwati emiti sechikamu chokudya kwadzo. Zvisinei, mabheya anowanzovaka madhamu nedzimba achishandisa mapazi emiti yakawa nezvimwe zvinomera zvaanoruma nemazino kuitira kuti agadzire zvinhu zvinodzivirira kuyerera kwemvura uye pokugara.
