Ubuchwepheshe Bokulandelela Busiza Ukubhala Ukufuduka Kokuqala Okunganqamuki Kwentsha iWhimbrel isuka e-Iceland iye eNtshonalanga Afrika

Ku-ornithology, ukufuduka kwezinyoni ezincane ezikude kuye kwaba yindawo enzima yocwaningo. Thatha i-Eurasian Whimbrel (I-Numenius phaeopus), isibonelo. Nakuba ososayensi belandele kabanzi amaphethini okufuduka emhlabeni wonke kwabantu abadala abakhalayo, beqoqa idatha eningi, ulwazi mayelana nezingane ezincane beluyivelakancane kakhulu.

Izifundo ezedlule zikhombisile ukuthi ama-whimbrel amadala abonisa amasu ahlukene okufuduka ngesikhathi sokuzala ngo-Ephreli nangoMeyi lapho ehamba esuka ezindaweni zawo zasebusika eya ezindaweni zawo zokuzalela. Amanye andizela ngqo e-Iceland, kanti amanye ahlukanisa uhambo lwawo lube yizigaba ezimbili ngokuma. Kamuva, kusukela ekupheleni kukaJulayi kuya ku-Agasti, ama-whimbrel amaningi amadala andizela ngqo ezindaweni zawo zasebusika eNtshonalanga Afrika. Kodwa-ke, ulwazi olubalulekile mayelana nama-small—njengemizila yawo yokufuduka kanye nesikhathi—luhlale luyimfihlakalo isikhathi eside, ikakhulukazi ngesikhathi sokufuduka kwawo kokuqala.

Esifundweni samuva nje, ithimba locwaningo lase-Iceland lisebenzise amadivayisi amabili okulandelela alula athuthukiswe yi-Global Messenger, amamodeli i-HQBG0804 (4.5g) kanye ne-HQBG1206 (6g), ukuqapha ama-whimbrel ayi-13 ezingane. Imiphumela yembule ukufana okuthakazelisayo kanye nomehluko phakathi kwama-whimbrel ezingane kanye nabantu abadala ngesikhathi sokufuduka kwazo kokuqala eNtshonalanga Afrika.

Njengabantu abadala, ama-whimbrel amaningi asemancane akwazile ukwenza umsebenzi omangalisayo wokundiza engami esuka e-Iceland eya eNtshonalanga Afrika. Kodwa-ke, kwabonakala nomehluko ohlukile. Ama-whimbrel asemancane ngokuvamile ahamba kamuva kule sizini kunabantu abadala futhi ayenamathuba amancane okulandela indlela eqondile yokufuduka. Kunalokho, ayema ​​kaningi endleleni futhi andize kancane. Ngenxa yabathungathi be-Global Messenger, ithimba lase-Iceland lathwebula, okokuqala, uhambo lokufuduka olungami lwama-whimbrel asemancane esuka e-Iceland eya eNtshonalanga Afrika, enikeza idatha ebalulekile yokuqonda ukuziphatha kokufuduka kwentsha.

Umfanekiso: Ukuqhathaniswa kwamaphethini okundiza phakathi kwama-whimbrels amadala namancane ase-Eurasia. Iphaneli a. ukuklewula kwabantu abadala, iphaneli b. Izingane.
