Itekhnoloji yokulandelela inceda ukurekhoda ukufuduka kokuqala okungayekiyo kukaWhimbrel oselula esuka eIceland ukuya eNtshona Afrika

Kwi-ornithology, ukufuduka kweentaka eziselula ukusuka emgama omde kuye kwahlala kuyindawo enzima yophando. Thatha i-Eurasian Whimbrel (Numenius phaeopus), umzekelo. Nangona izazinzulu ziye zalandela ngokubanzi iipatheni zokufuduka kwabantu abadala kwihlabathi liphela, ziqokelela ulwazi oluninzi, ulwazi malunga nabantwana abancinci belunqabile kakhulu.

Izifundo zangaphambili zibonise ukuba ii-whimbrel ezindala zibonisa iindlela ezahlukeneyo zokufuduka ngexesha lokuzala ngo-Epreli nangoMeyi xa zihamba ukusuka kwiindawo zazo zasebusika ukuya kwiindawo zazo zokuzalela. Ezinye zibhabha ngqo e-Iceland, ngelixa ezinye zahlula uhambo lwazo lube ngamacandelo amabini ngokuma. Kamva, ukususela ekupheleni kukaJulayi ukuya ku-Agasti, uninzi lwee-whimbrel ezindala zibhabha ngqo kwiindawo zazo zasebusika eNtshona Afrika. Nangona kunjalo, ulwazi olubalulekileyo malunga nee-whimbrel ezincinci—ezifana neendlela zazo zokufuduka kunye nexesha—luye lwahlala luyimfihlakalo ixesha elide, ingakumbi ngexesha lokufuduka kwazo kokuqala.

Kuphononongo lwakutshanje, iqela lophando lase-Iceland lisebenzise izixhobo ezimbini zokulandelela ezikhaphukhaphu ezenziwe yiGlobal Messenger, iimodeli ze-HQBG0804 (4.5g) kunye ne-HQBG1206 (6g), ukuze zijonge ii-whimbrels ezili-13 zolutsha. Iziphumo zityhile ukufana okumangalisayo kunye nomahluko phakathi kwee-whimbrels zolutsha kunye nezo zabantu abadala ngexesha lokufudukela kwazo eNtshona Afrika okokuqala.

Njengabantu abadala, uninzi lwee-whimbrels eziselula zikwazile ukwenza into emangalisayo yokubhabha zingayeki ukusuka e-Iceland ukuya eNtshona Afrika. Nangona kunjalo, kwabonakala umahluko owahlukileyo. Ii-whimbrels zihlala zikhwela kamva kwixesha lonyaka kunabantu abadala kwaye zazingenamdla wokulandela indlela ethe ngqo yokufuduka. Endaweni yoko, zazima rhoqo endleleni kwaye zibhabha kancinci. Ngenxa yabalandeleli beGlobal Messenger, iqela lase-Iceland libambe okokuqala, uhambo lokufuduka olungayekiyo lwee-whimbrels eziselula ezivela e-Iceland ukuya eNtshona Afrika, zibonelela ngedatha ebalulekileyo yokuqonda indlela yokuziphatha kokufuduka kolutsha.

Umfanekiso: Uthelekiso lweepateni zokubhabha phakathi kwee-whimbrels ezindala neziselula zase-Eurasia. Iphaneli a. ii-whimbrels zabantu abadala, iphaneli b. Amantshontsho.
