Mbalame zomwe zimasamuka ndi mbalame zomwe zimawulukira kutali kupita kumalo otentha chaka chilichonse. Iwo amakhala kumeneko nyengo yozizira. Mbalame zomwe zimasamuka ndi adokowe, cranes, atsekwe, ndi mbalame zina zambiri. Mbalame zomwe zimathera chaka chonse mochuluka kapena mocheperapo pamalo amodzi zimatchedwa "mbalame zongokhala".
Kusintha kwa malo kumeneku nthawi zosiyanasiyana za chaka n'kofunika kwambiri kuti apulumuke ndipo kumachitika nthawi imodzi chaka chilichonse. Nthawi zambiri zimauluka mofanana. Khalidwe limeneli ndi lachibadwa, ndiko kuti, lilipo kuyambira pa kubadwa.
Kodi tili ndi mbalame zotani zomwe zimasamukasamuka?
Kuchokera kumalingaliro athu, pali mitundu iwiri: mtundu umodzi umathera chilimwe ndi ife ndi nyengo yozizira kum'mwera, kumene kumakhala kofunda. Izi ndi mbalame zenizeni zomwe zikusamuka. Mitundu ina imathera m’chilimwe kumpoto kwakutali ndipo m’nyengo yozizira imakhala nafe chifukwa kudakali kotentha kwambiri kuno kuposa kumpoto. Amatchedwa "mbalame za alendo".
Choncho mbalame zosamukasamuka zimakhala ku Ulaya m’nyengo yachilimwe. Izi ndi, mwachitsanzo, mitundu ya adokowe, nkhaka, nightingales, swallows, cranes, ndi ena ambiri. Amatisiya m’dzinja n’kubweranso m’chilimwe. Ndiye kumakhala kofunda ndipo masiku ndi otalika, zomwe zimapangitsa kuti azilera ana mosavuta. Kuli zakudya zokwanira osati zolusa monga kumwera.
Nthaŵi yozizira ikafika kuno ndipo chakudya chikasoŵa, amasamukira kum’mwera, makamaka ku Africa. Kumeneko kukutentha kwambiri kuposa pano panthawiyi. Kuti zipulumuke pa maulendo ataliatali amenewa, mbalame zosamuka zimadya ziwiya zonona zisanachitike.
Mbalame za alendozi zimalekereranso kutentha pang'ono. Choncho, nyengo yachilimwe imakhala kumpoto ndi kuberekera ana awo kumeneko. M'nyengo yozizira kumazizira kwambiri kwa iwo ndipo amawulukira kwa ife. Zitsanzo ndi tsekwe wa nyemba kapena khola la red-crested pochard. M’maonedwe awo, ndiko kum’mwera. Kumatentha kumeneko kwa iwo.
