Pfupiso:
Kuchengetedza shiri dzinotama kwakaoma nekuda kwekuvimba kwadzo nenzvimbo dzakawanda dziri kure pamatanho akasiyana ehupenyu hwadzo hwegore negore. Pfungwa ye "flyway", iyo inoreva nzvimbo dzese dzinofukidzwa nekuberekesa, kusaberekesa, uye kutama kweshiri, inopa hurongwa hwekushandira pamwe kwenyika dzese kuchengetedza. Zvisinei, munzira imwe chete yekubhururuka, mabasa ekutama emhando imwe chete anogona kusiyana zvakanyanya pakati pemwaka nehuwandu hwevanhu. Kujekesa musiyano wemwaka nehuwandu hwevanhu mukutama kunobatsira kunzwisisa ecology yekutama uye kuona mipata yekuchengetedza. Nzira Tichishandisa satellite-tracking takatevera kutama kweWhimbrels (Numenius phaeopus variegatus) kubva kunzvimbo dzisiri dzekuberekesa paMoreton Bay (MB) neRoebuck Bay (RB) muAustralia muEast Asian-Australasian Flyway. Miedzo yeMantel yakashandiswa kuongorora simba rekubatana kwekufamba pakati penzvimbo dzisiri dzekuberekesa uye dzekuberekesa dzeMB neRB. Bvunzo yeWelch yakashandiswa kuenzanisa mabasa ekutama pakati pemapoka maviri uye pakati pekufamba kuchamhembe nekumaodzanyemba. Mhedzisiro Munguva yekutama kwemhuka kuenda kuchamhembe, daro uye nguva yekutama kwadzo dzaive dzakareba kune vanhu veMB pane vanhu veRB. Kureba uye nguva yekubhururuka kwekutanga panguva yekutama kwemhuka kuenda kuchamhembe kwaive kwakareba kune vanhu veMB pane vanhu veRB, zvichiratidza kuti vanhu veMB vaiisa mafuta akawanda vasati vabva panzvimbo dzisingabereke kuti vatsigire kubhururuka kwavo kwenguva refu vasingamire. Vanhu veRB vakaratidza kusabatana kwekufamba kwavo (nzvimbo dzekuberekesa dzichipararira munzvimbo dzakasiyana dzemarefu makumi matanhatu) kupfuura vanhu veMB (nzvimbo dzekuberekesa dzakanyanya munzvimbo dzakasiyana dzemarefu mashanu muFar Eastern Russia). Zvichienzaniswa nehuwandu hwevanhu veMB, huwandu hwevanhu veRB hwainyanya kuvimba nenzvimbo dzekumira muYellow Sea nenzvimbo dziri kumahombekombe muChina, uko nzvimbo dzemvura dzakarasikirwa zvikuru. Zvisinei, huwandu hwevanhu veRB hwakawedzera nepo huwandu hwevanhu veMB hwakaderera mumakumi emakore apfuura, zvichiratidza kuti kurasikirwa nenzvimbo dzemvura munzvimbo dzekumira hakuna kukanganisa zvakanyanya huwandu hwevanhu veWhimbrel, avo vanogona kushandisa mhando dzakasiyana dzenzvimbo. Mafambiro akasiyana pakati pevanhu anogona kunge ari nekuda kwemazinga akasiyana ekumanikidzwa kwekuvhima munzvimbo dzavo dzekuberekesa. Mhedziso Chidzidzo ichi chinosimbisa kuti matanho ekuchengetedza anogona kuvandudzwa nekunzwisisa hupenyu hwese hwegore hwekufamba kwemarudzi akasiyana eWhimbrels pamwe nedzimwe shiri dzinotama.
