It has a memory chip here, 這是個很簡單的RIFD裝置。 它有一個內存芯片在這裡。 and anytime a bird with a PIT tag lands on here, 和任何時候的鳥 與PIT標籤降落在這裡, on the circuit board we’re recording the date, 在電路板上,我們正在記錄日期。 the time to the second, 時至秒。 and the ID number of that bird. 以及該鳥的ID號。 One of the really neat things about the RIFD technology is that it’s been around since the 70s. 關於RIFD技術的一個真正整潔的事情是,它從70年代就開始了。 It’s not cutting edge technology, it’s in boxes that Walmart uses in distribution centers 這不是什麼尖端科技,而是沃爾瑪在配送中心使用的盒子裡 that tracks the boxes, it’s in our passports. 追蹤箱子,它是在我們的護照。 So, passive integrated transponder technology is out there. It has widespread commercial use, which makes it cheap for us 所以,無源集成應答器技術是有的。它有廣泛的商業用途,這使得我們的成本很低。 because companies are using it like crazy. 因為公司正在瘋狂地使用它。 When this technology came along and that light bulb went off 當這個技術出現,那個燈泡熄滅了的時候。 –hey, we can actually use this to understand the behavior of the individual birds, around the clock -嘿,我們其實可以用這個來了解單個鳥類的行為,晝夜不停地進行 – how they feed during the day, their daily patterns of foraging behavior, - 它們在一天中如何進食,它們每天的覓食行為模式。 how that changes throughout the course of the year, how birds switch their diet from season to season. 在一年中如何變化,鳥類如何從一個季節到另一個季節轉換它們的飲食。 All of these questions we can look at because of these little PIT tags 所有這些問題我們都可以看,因為這些小PIT標籤 that we’re putting on the legs of individual birds and tracking their individual behaviors. 我們給每隻鳥兒的腿上都貼了標籤 追蹤它們的個體行為 Live long and prosper. 長命百歲,興旺發達。 And students really love it. 而學生們也非常喜歡。 Change the battery…connect the circuit board to the computer. 換電池......把電路板連到電腦上。 4,000 hits at this one. 4000次點擊率,在這個。 We’re tracking about 125 individual birds of four species 我們正在追蹤四種鳥類的125只個體。 and from those 125 birds in the last two years we've recorded over 從這125只鳥在過去的兩年中,我們'記錄超過 2.2 million visits to the bird feeders that we have out in the woods here. 220萬人次到我們在這裡的樹林裡的喂鳥器。 We were blown away and thrilled 我們被嚇到了,激動不已 with the amount of data coming in from this really simple technology. 隨著這個真正簡單的技術所帶來的數據量。 And it's open up a whole world of new research and new avenues that we can travel down 它打開了整個世界的新研究和新的途徑,我們可以走下去。 and get students involved with to learn more about the natural world, focusing in on common backyard feeder birds 並讓學生參與進來,瞭解更多的自然界,重點是在常見的後院餵養鳥類 which are the model organisms for answering bigger scientific questions. 哪些是回答更大科學問題的模式生物。 We’ll just put it back together, 我們只是把它重新組裝起來。 fill it up with seed. 用種子填滿它。 One of the great powers of citizen science is that we’ve got people out there 公民科學的一個偉大的力量是 我們已經得到了人們在那裡。 watching birds everywhere in all sorts of different ecosystems and environments. 在各種不同的生態系統和環境中觀察各地的鳥類。 And since this technology is relatively inexpensive 而且由於這種技術相對便宜 and easy to use, I think we have the potential to expand, 且使用方便,我認為我們有拓展的潛力。 expand this research out and develop a network and answer some of those bigger questions. 把這個研究擴展出來,發展一個網絡,回答一些比較大的問題。
