Pfupiso:
Ruzivo rwezvinodiwa neshiri dzinotama rwakakosha pakugadzira zvirongwa zvekuchengetedza mhuka dzinotama dziri munjodzi. Chidzidzo ichi chaive nechinangwa chekuona nzira dzekutama, nzvimbo dzechando, mashandisirwo enzvimbo dzekugara, uye kufa kweshiri dzeChinese Egrets (Egretta eulophotata) dzakura. 60 Chinese Egrets dzakura (hadzi 31 nehurume 29) pachitsuwa chisina vanhu vanogara kunze kwenyika muDalian, China dzakateverwa dzichishandisa GPS satellite transmitters. Nzvimbo dzeGPS dzakanyorwa maawa maviri kubva muna Chikumi 2019 kusvika Nyamavhuvhu 2020 dzakashandiswa pakuongorora. Huwandu hwevanhu vakuru 44 ne17 vakatevera vakapedza kufamba kwavo kwematsutso nechirimo, zvichiteerana. Zvichienzaniswa nekufamba kwematsutso, shiri dzakatevera dzakaratidza nzira dzakasiyana-siyana, nhamba yakakura yenzvimbo dzekumira, kumhanya kwekutama zvishoma nezvishoma, uye nguva yakareba yekutama muchirimo. Zvakabuda zvakaratidza kuti shiri dzinotama dzaiva nemaitiro akasiyana panguva yekufamba kweshiri mbiri. Nguva yekutama kwechirimo nenguva yekumira kwechirimo kweshiri dzechikadzi yaive yakareba zvakanyanya kupfuura yehurume. Paive nehukama hwakanaka pakati pemazuva ekusvika kwechirimo nekubva kwechirimo, pamwe chete nepakati pezuva rekusvika kwechirimo nenguva yekumira. Zvakawanikwa izvi zvakaratidza kuti maegret akasvika nekukurumidza panzvimbo dzekuberekera aibva munzvimbo dzechando nekukurumidza uye aimbomira kwenguva pfupi. Shiri huru dzaifarira nzvimbo dzine mvura zhinji, masango, uye madziva ekupfuya shiri panguva yekutama. Munguva yechando, makuru aifarira zvitsuwa zviri kure, nzvimbo dzine mvura zhinji pakati pemvura, uye madziva ekupfuya shiri. Maegret ekare eChinese akaratidza mwero wekurarama wakaderera zvichienzaniswa nemamwe marudzi mazhinji eArdeid akajairika. Mienzaniso yakafa yakawanikwa mumadziva ekupfuya shiri, zvichiratidza kuti kukanganiswa kwevanhu ndicho chikonzero chikuru cherufu rwemhando iyi isina njodzi. Mhedzisiro iyi yakaratidza kukosha kwekugadzirisa kusawirirana pakati pemaegret nenzvimbo dzakagadzirwa nevanhu dzinopfuya shiri uye kuchengetedza nzvimbo dzakati sandara dziri pakati pemvura nezvitsuwa zviri kure munzvimbo dzine mvura zhinji kuburikidza nekushandira pamwe kwenyika. Mhedzisiro yedu yakabatsira pakufamba kwemarudzi eegret ekare eChinese asina njodzi pagore, nokudaro ichipa hwaro hwakakosha hwekuchengetedzwa kwemhando iyi isina njodzi.
