Research is not the same as birdwatching for pleasure. Researchers must also find the birds 'nests and habitat, and to gain a more complete understanding of the animals themselves, must trap them and attach radio transmitters to them to assist track ing.
研究畢竟不是賞鳥，必須進一步找到鳥巢、棲息地點，為了更完整瞭解動物本身，還得設法捕捉鳥、上無線電發報器利於追蹤。
