Isingeniso: Ziyini Izimpaphe Ezingangeni Manzi?
Izimpaphe zingenye yezici ezihluke kakhulu ezinyonini, futhi zenza imisebenzi ehlukahlukene, ehlanganisa ukundiza, ukuhlukanisa izinto nokubonisa. Kodwa-ke, akuzona zonke izimpaphe ezidalwe zilingana, futhi ezinye zenzelwe injongo ethile. Izimpaphe ezingangeni manzi, ezaziwa nangokuthi yi-contour feathers, ziyindlela ebalulekile yokujwayela izinyoni zasemanzini njengamadada, amadada, namahansi. Lezi zimpaphe zenzelwe ukuxosha amanzi futhi zigcine umzimba wenyoni womile, ngisho nalapho zibhukuda noma zitshuza.
Ukubaluleka Kwezimpaphe Ezingangeni Manzi Emadada
Izimpaphe ezingangeni manzi zibalulekile ukuze amadada aphile, njengoba echitha isikhathi esiningi emanzini naseduze namanzi. Lezi zimpaphe zivimbela umzimba wenyoni ekubeni manzi, okubalulekile ukugcina izinga lokushisa lomzimba nokugwema i-hypothermia. Ukwengeza, izimpaphe ezingangeni manzi zisiza amadada ukuba ahlale evunulile futhi akwazi ukuhamba ngokuphumelelayo emanzini, okwenza kube lula ngawo ukuba athole ukudla futhi agweme izilwane ezidla ezinye. Ngaphandle kwezimpaphe ezingangeni emanzini, amadada abengakuthola kunzima ukuphila ezindaweni zawo ezihlala emanzini.
