Hom (Avian):Hooded Crane (Grus monacha)

Abstract:

Hooded Crane (Grus monacha) tau teev tseg raws li hom kab mob tsis zoo los ntawm IUCN. Kev paub txog kev tsiv teb tsaws ntawm Hooded Crane tseem txwv. Ntawm no peb tau tshaj tawm cov qauv kev tsiv teb tsaws chaw ntawm Hooded Cranes lub caij ntuj no hauv Izumi, Nyij Pooj, nrog rau cov chaw nres tsheb tseem ceeb rau lawv txoj kev txuag. Plaub tus neeg laus thiab tsib subadult cranes, txhua lub caij ntuj no hauv Izumi, Nyiv, tau haum nrog satellite transmitters (GPS-GSM system) ntawm lawv qhov chaw nres tsheb nyob rau sab qaum teb 10 15 hnub ntawm Tuam Tshoj thiab 2 lub sijhawm ntawm cov neeg laus. thiab subadults nyob rau hauv caij nplooj ntoos hlav thiab lub caij nplooj zeeg tsiv teb tsaws, nrog rau lub sij hawm thiab lub sij hawm lawv nyob rau hauv kev yug me nyuam thiab wintering av. Tsis tas li ntawd, peb tau soj ntsuam kev siv av ntawm cov cranes hauv cov chaw nres tsheb. Cov neeg laus cranes siv sijhawm ntev dua los mus rau sab qaum teb thaum lub caij nplooj ntoo hlav (txhais tau tias = 44.3 hnub) thiab sab qab teb hauv lub caij nplooj zeeg (txhais tau tias = 54.0 hnub) piv nrog subadult cranes (15.3 thiab 5.2 hnub, feem). Txawm li cas los xij, cov subadults muaj lub caij ntuj no ntev (txhais tau tias = 149.8 hnub) thiab nomadic (lub caij yug me nyuam rau cov neeg laus) lub caij (txhais tau tias = 196.8 hnub) piv rau cov neeg laus (133.8 thiab 122.3 hnub, feem). Peb qhov chaw nres tsheb tseem ceeb tau raug txheeb xyuas: thaj tsam ncig Muraviovka Park hauv Russia, Songnen Plain hauv Suav teb, thiab sab hnub poob ntug dej hiav txwv ntawm Kaus Lim Qab Teb, qhov chaw cranes siv sijhawm feem ntau ntawm lawv txoj kev tsiv teb tsaws chaw (62.2 thiab 85.7% nyob rau lub caij nplooj ntoos hlav thiab caij nplooj zeeg, feem). Thaum tsiv teb tsaws chaw, lub caij nomadic thiab lub caij ntuj no, Hooded Cranes feem ntau nyob hauv cov qoob loo rau so thiab pub mis. Nyob rau lub caij ntuj no tsis yog lub caij ntuj no, tsawg dua 6% ntawm qhov chaw nres tsheb tau nyob hauv thaj chaw tiv thaiv.Zuag qhia tag nrho, peb cov txiaj ntsig tau ua rau nkag siab txog txhua xyoo spatio-temporal migration qauv ntawm Hooded Cranes nyob rau sab hnub tuaj flyway, thiab npaj kev txuag kev ntsuas rau hom no.
