Soo Koobid:
Labaatan Geese oo Bariga Fog ah oo Greylag ah, Anser anser rubrirostris ah, ayaa la qabtay oo lagu rakibay Nidaamka Meelaynta Caalamiga ah/Nidaamka Caalamiga ah ee Isgaarsiinta Moobaylka (GPS/GSM) si loo aqoonsado meelaha taranka iyo jiilaalka, waddooyinka socdaalka iyo goobaha joogsiga. Xogta Telemetry markii ugu horreysay waxay muujisay isku xirka u dhexeeya meelaha jiilaalka ee Webiga Yangtze, goobaha joogsiga ee waqooyi-bari Shiinaha, iyo goobaha taranka/qoynta ee bariga Mongolia iyo waqooyi-bari Shiinaha. 10 ka mid ah 20-ka qof ee calaamadaysan ayaa bixiyay xog ku filan. Waxay ku hakadeen socdaalka Webiga Yellow River Estuary, Kaydka Beidagang iyo Webiga Xar Moron, taasoo xaqiijinaysa in meelahan ay yihiin goobo muhiim u ah joogsiga dadkan. Muddada dhex-dhexaadka ah ee socdaalka gu'ga wuxuu ahaa 33.7 maalmood (shakhsiyaadku waxay bilaabeen inay u guuraan inta u dhaxaysa 25 Febraayo iyo 16 Maarso waxayna dhammaystireen guuritaanka laga bilaabo 1 ilaa 9 Abriil) marka la barbar dhigo 52.7 maalmood dayrta (26 Sebtembar - 13 Oktoobar ilaa 4 Noofambar - 11 Diseembar). Muddada joogsiga dhexdhexaadka ah waxay ahayd 31.1 iyo 51.3 maalmood, xawaaraha dhexdhexaadka ah ee safarkuna wuxuu ahaa 62.6 iyo 47.9 km/maalintii socdaalka gu'ga iyo dayrta, siday u kala horreeyaan. Farqiga weyn ee u dhexeeya socdaalka gu'ga iyo dayrta ee muddada socdaalka, muddada joogsiga iyo xawaaraha socdaalka ayaa xaqiijiyay in Greylag Geese oo qaangaar ah uu si dhakhso leh u safray guga marka loo eego dayrta, isagoo taageeraya mala-awaalka ah in ay tahay inay waqti badan ku xaddidan yihiin inta lagu jiro socdaalka gu'ga.
