E rua ngā āhua o te mura o te guano: ko te mura e puta mai ana i te kohikohinga o te mata o te ārai. Heoi, nā te mea he maha ngā wāhanga o ngā manu e wehea ana e te maru ārai, he iti rawa te tūponotanga o te mura tika. Ko tētahi atu ko te paheke o te guano i te taha o waho, ka puta te pakaru poto i waenga i ngā taputapu koura o runga me raro i te pūtake tika, ā, kāore he tohu guano e toe ana i runga i te sueko, koinei hoki te āhua matua o te mura guano. I runga i te whai huatanga o te whakatauira i te āhuatanga mura o ngā manu ārai, kua ako te tari hangarau hiko o te whare wānanga o Tsinghua i te tikanga mura me ngā āhuatanga mura o te guano, ā, kua whakatau ko te wā hinga o te guano ka whakararu i te tohatoha o te mara hiko huri noa i te ārai, ka pakaru te āputa hau o te awa guano i te pito teitei o te ārai, ka puta te mura o te ārai. Hei tauira, ko te suozi hangai 110 kv, me tiaki te porowhita me te diameter o te 55cm e te fantian. I taua wā anō, whakaarohia te hau e taka ana pērā i te parabola. I roto i ngā mahi tūturu, ko te rohe whakawhiti i te tihi o te pourewa ka kiia ko te mea nui mō te ārai manu i roto i te awhe 30-45° me te aho ārai hei pūtake me te koki i waenganui i ngā taha e rua. Tuarua, kia mau ai te mātotoru o te manu, ka "mono" katoatia ngā manu ki waho o te rohe tiaki.

I roto i te whakamahinga hangarau, nā te uaua o te momo pourewa, ka mahue pea ētahi wāhi matua o te tiaki manu, ka hua ake he hapa kino manu. Kua tāutahia ngā titi manu i runga ake i te ārai o te waea toru-wāhanga ki tōna wāhi, engari kāore te tataramoa manu i tāutahia ki te pou whenua i runga ake i te waea taha, ka waiho he raruraru huna mō te puta o te hapa.
