Ehandle ka ndzhawu yale Greater Cape Town, atitali kukumeka kutlula kwalomu ka ti kilomitara nyana laha kungariki na mati ya lwandle. Swinyenyani leswingana kutlula 24 wa malembe switsarisiwile xikan’we na swinyenyani leswinga haha kutlula 1 211 km kusuka e swisakeni swa swona, hambi leswi switlhelaka switlhelela eka mintlawa ya swona.
Ku Dlaya na Madyelo
Tinyenyani leti titala ku hlengeletana eka tindzhawu letingana swakudya, kambe titlhela titiveka kuva tihlasela valala tani hi ntlawa, laha hi xitalo titalaka ku hlasela matihlo ya nala watona. Madyelo yatona ya fana swinene nalawa ya tinyenyani tati crows, laha loko ti hlasela ntsumbu tisungula hile matihlweni lawa se yanga pfuriwa, nomo xikanwe na xirho xale xihundleni.
Vulawuri
Seagulls i tinyenyani letinga sirheleriwa, se van’wamapurasi vafanele kukuma mpfumelelo kuva va tilawula. Ku sivelela nhlaselo, hambiswiritano, swikahle kuva ku hungutiwa swakudya leswingariki swa ntumbuluko, hikuva ku antswisiwa malahlelo ya malakatsa. Swibye swo chela thyaka swifanele kuva leswi hlayisekeke, swo phamela eka swona tinyenyani swifanele ku susiwa xikan’we na swibye swa swakudya swa timbyana kumbe swimanga swifanele kupfaleriwa eka tindzhawu ta nhlayiseko.
Swisirhelelo swa mpfumawulo na leswivonakaka tani hiti reflectors kumbe ti scarecrows, tinga tirhisiwa ku chavisa swinyenyani leswaku tiya kule na swifuwo naswona magoza yafanele kutekiwa kusirhelela swifuwo loko swiri e khombyeni. Swa xisati leswinga biha emirini tani hi xikombiso, swifanele kususiwa kuya eka tinkamba letintsongo, laha swi olovaka kuva kuva na murisi loyi angata risa swifuwo leswi, mavhiki nyana loko swinga se ya tswala naswona swita tshama kona ku ringana loko vana vangahari e khombyeni.
