He nui nā poʻe pā i kū i nā pilikia e like me ka laweʻana i ka hulu o lākou iho. ʻO nā kumu e hume ai i ka hulu, kahi paha.
ʻO nā kumu no nā kāloka pono'ī
ʻO kekahi o nā kumu e hiki ai keʻaiʻole i ka'ōpala, i kaʻiliahi , i ka hulu manu. Ma keʻano hoʻomaluʻana i kāna puaʻa, uaʻona pinepine ka mea nona ka waiwai i kāna "mea maikaʻi" mai kona papaʻaina. ʻO kēia ka hopena i ka hopena o ka hanuʻana a me ka hopena o keʻano o ka momona, kahi a ka manu e ho'āʻo ai e ho'ōla ma ka huluʻana i nā hulu a hoʻohui me ka beak o kaʻili. Eia kekahi, hoʻokaʻawaleʻia mai nā hua'ōleʻa manu. No nā kāleka āpau, hikiʻole ke neʻe nui,ʻo kēia mauʻanoʻano, no ko lākou momona momona, he kumu kūpono paha no ka hukiʻana o nā hulu. ʻO ke kumu hou aʻe he parasites (fungus, mites, downy-noses). Hiki ke hoʻopauʻia me ke kōkuaʻana o nā lāʻau lapaʻau i'ōleloʻia e ka mea kauā. I ka manawa pinepine, e huki i nā hulu manu ma kekahi wahi, no ka laʻana, ma lalo o nā'ēheu. Maʻaneʻi, inā haʻaleleʻia nā kumu i luna nei, hiki i ka pilikia i loko o ka mimiho o nā hulu manu.
I kekahi manawa, ke kumu o ka hukiʻana i nā hulu o kahi pālolo, hiki ke hana i ka pilikia paalā a iʻole nā mea i loko o kahi kūlana hoʻoluʻolu. ʻO kahi laʻana, hiki i nā kāleka Corellia ke ohi i nā hulu manu no kaʻike i loko o nā pūhaka kokoke. ʻO kahi manu lele, ma keʻano he manu i aloha nuiʻia,ʻaʻohe o ka noho haʻahaʻa a me ka nānāʻole i ko lākou kino. ʻAʻole kēia wale nō ka mea e hoʻonāukiuki ai, e hōʻike ai, e komo pū ana i loko o nā hulu manu, akā hiki nō ke alakaʻi i ka makeʻana o ka manu. He aha e hana ai i nā mea e huki ai i kaʻulu o ka hulu? ʻO ke ala maikaʻi loa,ʻo ia ke hoʻopili aku i kahi kanaka lapaʻau e pili ana i ka mālamaʻana i nā manu. Ināʻo ke kumu o ka laweʻana iā ia iho i kekahi maʻi , e'ōleloʻo ia i kekahi mau lāʻau. Ināʻole
