Kunezinhlobo eziyi-8 zama-pelican emhlabeni. Lezi yizinyoni zamanzi, izinyoni ezidla inyama, ziyadoba ogwini lolwandle kanye / noma emachibini nasemifuleni. AmaPelican asebenzisa izinyawo ezine-webbed ukuhamba ngokushesha emanzini, ukubamba izinhlanzi ngemilomo yazo emide - umthombo wokudla oyinhloko. Izinhlobo eziningi ziyacwila futhi zibhukude zijule ngaphansi kwamanzi ukuze zibambe inyamazane yazo.
IsiPelican
Incazelo yesiPelican
Zonke izinhlobo ze-pelican zinemilenze enezinzwane ezine ezine-webbed. Ama-paws amafushane, ngakho-ke ama-pelican asemhlabeni abukeka kabi, kepha lapho engena emanzini, aba abazingeli ababhukudi abanomusa.
Zonke izinyoni zinemilomo emikhulu enesikhwama somphimbo ezibamba ngaso inyamazane futhi zikhiphe amanzi. Amasaka nawo ayingxenye yomcimbi womshado futhi alawula ukushisa komzimba. AmaPelican anamaphiko amakhulu, andiza ngobuchule emoyeni, futhi awabhukudi emanzini kuphela.

Indawo yokuhlala yasePelican
AmaPelican ahlala kuwo wonke amazwekazi ngaphandle kwase-Antarctica. Ucwaningo lwe-DNA lukhombisile ukuthi ama-pelican ayizinhlobo ezintathu eziyinhloko:
- Izwe Elidala (elimpunga, elipinki nelase-Australia);
- ivuba elikhulu elimhlophe;
- Umhlaba Omusha (onsundu, waseMelika omhlophe nowasePeruvia).
AmaPelican adoba emifuleni, emachibini, ezilwandle nasezizalweni zemifula. Kepha kwesinye isikhathi bazingela ama-amphibian, ama-turtles, ama-crustaceans, izinambuzane, izinyoni nezilwane ezincelisayo. Ezinye izinhlobo zezidleke ezisogwini eduze kwezilwandle nolwandle, ezinye ziseduze namachibi amakhulu ezwekazi.
Ukudla nokuziphatha kwama-pelican
AmaPelican abamba inyamazane yawo ngemilomo yawo bese eqeda amanzi asezikhwameni ngaphambi kokugwinya ukudla okuphilayo. Ngalesi sikhathi, ama-gull nama-terns azama ukweba izinhlanzi ngomlomo wazo. Izinyoni zizingela zodwa noma ngamaqembu. AmaPelican angena emanzini ngejubane elikhulu, abambe inyamazane. Amanye ama-pelican athutha amabanga amade, amanye ahlala phansi.
AmaPelican ayizidalwa zomphakathi, akha izidleke emakoloni, kwesinye isikhathi ababheki bezinyoni babalelwa ezinkulungwaneni zamabhangqa endaweni eyodwa. Uhlobo olukhulu kunawo wonke - abamhlophe abakhulu, abamhlophe baseMelika, izikele zase-Australia namapelican agobile - isidleke phansi. Izilokazana ezincane zakha izidleke ezihlahleni, ezihlahleni, noma onqenqemeni lwamadwala. Inhlobo ngayinye ye-pelican yakha izidleke zosayizi ngamunye nobunzima.
Ama-pelican azala kanjani
Isikhathi sokuzalisa ama-pelicans sincike ezinhlotsheni. Ezinye izinhlobo zizala izingane minyaka yonke noma njalo eminyakeni emibili. Ezinye zizalela amaqanda azo ngezikhathi ezithile zonyaka noma unyaka wonke. Umbala weqanda lepelican:
- Chalky;
- ngokubomvu;
- okuluhlaza okotshani;
- okuluhlaza okwesibhakabhaka.
Omama basePelican bazalela amaqanda ngemvuthu. Inani lamaqanda lincike ezinhlotsheni, ukusuka kowodwa kuya koyisithupha ngasikhathi sinye, futhi amaqanda afukanywa izinsuku ezingama-24 kuya kwezingama-57.
Izinyamazane zabesilisa nabesifazane zakha izidleke futhi zichamusele amaqanda ndawonye. Ubaba ukhetha indawo yokwakha izidleke, aqoqe izinti, izimpaphe, amaqabunga nokunye ukungcola, umama wakhe isidleke. Ngemuva kokuba insikazi izalele amaqanda, ubaba nomama bayashintshana ukuma phezu kwabo ngezidladla ezinamawebhu.
Bobabili abazali banakekela izinkukhu, bazondla ngezinhlanzi eziphinde zavuselelwa. Izinhlobo eziningi zinakekela inzalo kuze kufike ezinyangeni eziyi-18. Izinja ezincane zithatha iminyaka emithathu kuya kwemihlanu ukufinyelela ekuvuthweni ngokocansi.
