I-grebes enkulu kunazo zonke yase-Europe, enentamo ende nomlomo omude, ofana nommese. Lesi sakhiwo somlomo sitholakala ezinhlanzini ezizingela izinyoni zasemanzini, futhi empeleni, i-grebe e-crested, ngokungafani namanye ama-grebe, abamba izinhlanzi eziningi kakhulu kunezinambuzane ezingenamgogodla. Badla kusuka ku-3 cm okunamathela kuya kuma-eels ngaphezulu kwama-20 cm.
Ngabe bahlala kuphi amaGrebes
Izindle ezinkulu ezinkulu zidinga amanzi amaningi angenazitshalo ukuzingela izinhlanzi, ngakho-ke lolu hlobo aluhlali ezindaweni eziluhlaza zamanzi ezihlala ezinye izikhovu. Kukhona uhlaza olwanele ogwini, izinyoni zikusebenzisa njengehange lesidleke.
Imikhuba yokubonisana yamazwane amakhulu
Lezi zinyoni zichitha isikhathi sazo ngaphandle, ngakho-ke kulula ukuzibona, futhi ukuqomisana kwazo okuhlaba umxhwele kwaba isihloko sesinye sezifundo zokuqala ezinzulu zokuziphatha kwezinyoni.
Ukuhamba okuvame kakhulu wukuhamba "kwe-head shake", lapho amalungu alo mbhangqwana ebhukuda ebhekisa komunye nomunye, anikine amakhanda ngapha nangapha. Lo mcimbi uphazanyiswa ukususwa kwezimpaphe. Izindlezane, kubonakala ohlangothini, zihlwitha izimpaphe ngemuva kwalowo okhethiwe, kodwa empeleni zimane nje zinyakaze ngamakhanda azo. Bese kulandela izinkulumo eziyinkimbinkimbi zokuzwelana. Owesilisa nowesifazane bacwila ezitshalweni ezingaphansi kwamanzi, badabula iziqu, bavele futhi babhukude ngokushesha. Bahlangana isifuba nesifuba, bavuka emanzini, banikine amakhanda abo ngapha nangapha, basabambe ukhula ngomlomo.
Ngemuva kokukhetha umbhangqwana nokuqedela isiko elinemibala yokuqomisana, lapho izinyoni sezivele zenze umbimbi, ziqala ukuphila impilo yodwa, zibekele amaqanda.
Isidleke sesigaxa esikhulu
Izici zamatshwele akhulayo
Ama-Grebes anesikhathi eside ngokuzala eside. Amaqanda abekwa yizinyoni kusukela ngoFebhuwari kuya ku-Okthoba. Lo mbhangqwana wakha okungenani isidleke esisodwa. Izinyoni zakha “amapulatifomu” asizayo ezintantayo kwezinye izinhloso, kufaka phakathi ukukhwelana.
Ngesikhathi sokufukamela, umzali ohlezi (womabili amalungu alaba bobabili afukamela amaqanda) uyashiya esidlekeni uma ethola umhlaseli kude. Le nyoni imboza amaqanda ngo-algae, ngakho-ke asheshe ashintshe umbala kusuka kokumhlophe abe nsundu ngokufiphele. Lokhu kwenza ukuthi amaqanda angavamisi ukubonwa ngumzingeli.
Isicefu esihle esinamachwane
Amatshwele nawo asengozini yokudliwa uma ehlala esidlekeni isikhathi eside ngaphandle kukamama nobaba, ngakho-ke "ahamba ngezinyawo" emahoreni ambalwa emva kokuzalwa. Abazali bathwala amaphuphu amancane emhlane, ngakho-ke kulula ukuthi wonke umndeni ubhukude usuke osebeni.
Amachwane anemishwe, umbala wawo ufana nengubo yeziboshwa. Bakwazi kahle ukubhukuda ngokushesha nje lapho bechanyuselwa, kodwa ngenxa yokuphepha nokulondolozwa kokushisa komzimba, abancane babambelela ngemuva komunye wabazali, bahlala phakathi kwamaphiko. Baze babambelele emihlane yabo ngesikhathi sokuntywila kwabantu abadala.
Abancane bondliwa umzali oyedwa lapho izinyane lihlala ngemuva komunye. Ukucaciswa kokukhuliswa kamuva akukhona ekusebenzisaneni kweGrbe, kepha "ekwabiweni kwenzalo", ngenkathi umzali ngamunye ethola ilungelo lokugcina ingxenye yengane, engazinaki ezinye izinkukhu. Kepha kwesinye isikhathi amatshwele amadala avela kumantshontsho angaphambilini ajoyina ukondliwa kwabancane, asize noma umzali.
Indle enkulu yokubhabha endizeni
ICrested Grebe ijwayele indlela yokuphila yasemanzini. Ngakho-ke, kunzima ukuthi itoostool enkulu ime phezu kwephiko, ngokungafani, ithi, idlelo noma izinyoni zehlathi. Lapho ikhuphukela emoyeni, iyahlakazeka isikhathi eside, ilwa kanzima ukuphuma ebusweni bamanzi. Kungakho iGreatan Greater igwema amachibi namachibi amancane.
Kungani abantu bethanda ukubuka izinzwane ezinkulu
I-grease ebunjiwe emanzini ibukeka inomusa, izimpaphe ezihlotshisiwe nemikhuba emangazayo yokuqomisana yenza izinyoni zithandwa phakathi kwezilwane zasemanzini.
