Kev txheeb xyuas cov chaw yug me nyuam thiab cov kev cai txhua xyoo ntawm cov bohaii subspecies tshiab ntawm Black-tailed Godwits.

Hom (Noog):Tus Tsov Dub (Limosa limosa bohaii)

Phau ntawv xov xwm:Emu

Cov Lus Qhia Txog:

Tus Bohai Black-tailed Godwit (Limosa limosa bohaii) yog ib hom tsiaj tshiab uas tau tshawb pom hauv East Asian-Australasian Flyway. Raws li kev taug qab satellite ntawm 21 tus tib neeg uas tau raug cim nyob rau sab qaum teb Bohai Bay, Suav teb, txij xyoo 2016 txog 2018, peb piav qhia txog lub voj voog txhua xyoo ntawm cov hom tsiaj no. Tag nrho cov noog muaj Thaib teb ua lawv qhov chaw nyob 'lub caij ntuj no' sab qab teb. Lub caij nplooj ntoo hlav tawm mus thaum kawg Lub Peb Hlis thaum lub sijhawm tsiv teb tsaws chaw mus rau sab qaum teb, Bohai Bay yog thawj qhov chaw nres tsheb uas lawv siv sijhawm nruab nrab 39 hnub (± SD = 6 hnub), ua raws li Inner Mongolia thiab Jilin xeev (nres rau 8 hnub ± 1 hnub). Kev tuaj txog ntawm cov chaw yug me nyuam hauv Russia Far East tau nyob hauv nruab nrab thaum kawg Lub Tsib Hlis. Ob qhov chaw yug me nyuam tau pom, nrog qhov chaw nruab nrab 1100 km sib nrug; qhov chaw sab hnub tuaj dhau ntawm qhov paub txog kev faib tawm ntawm Black-tailed Godwit hauv Asia. Kev tsiv teb tsaws chaw mus rau sab qab teb tau pib thaum kawg Lub Rau Hli, nrog rau cov noog godwits feem ntau nres ntev dua ntawm ob qhov chaw nres tseem ceeb uas siv thaum lub caij nplooj ntoo hlav, piv txwv li Inner Mongolia thiab Jilin xeev (32 ± 5 hnub) thiab Bohai Bay (44 ± 8 hnub), nrog rau qee tus neeg nres thib peb hauv nruab nrab-qis ntawm Yangtze River hauv sab qab teb Suav teb (12 ± 4 hnub). Thaum kawg Lub Cuaj Hli, feem ntau cov neeg taug qab tau tuaj txog hauv Thaib teb. Piv nrog rau cov subspecies uas paub ua ntej, cov noog bohaii muaj cov sijhawm tsiv teb tsaws chaw thiab moult sib txawv heev, yog li kev tshawb fawb no ntxiv rau kev paub txog kev sib txawv ntawm cov noog dub-tailed hauv East Asian-Australian Flyway.
