eBird玩家系列 – 頂寮王鄭可

從2014年開始,鄭可經常前往宜蘭海岸利澤工業區內一個不起眼的小山丘 – 頂寮賞鳥,並上傳一筆筆完整紀錄清單到eBird帳號。至2017年7月在當地記錄超過200種鳥種。來看看是甚麼原因讓他看上頂寮,而除了累積鳥種數,長期的、同一地點的紀錄在eBird裡又可以怎麼玩。你可以利用eBird 資料探索 – 熱門鳥點地圖 工具,搜尋 宜蘭–頂寮生態公園(Yilan–Dingliao Ecological Park),進一步認識這個地方。

eBird Science: Distribution predictions using eBird data are comparable to those from satellite transmitters

Ever since satellite technology has been small enough to put on a bird, researchers have been using transmitters to ask questions about birds that were previously unanswerable. Although some questions still can’t be answered with anything aside from satellites (e.g., precise paths of migrating birds throughout their entire annual cycle), a paper published this week in Global Ecology and Conservation shows that eBird data can be comparable to satellite data when creating species distribution models. The authors of the open-access paper “Species distribution models for a migratory bird based on citizen science and satellite tracking data" have written a great account of their research on Band-tailed Pigeons (below). Thanks to Chris Coxen, Jennifer Frey, Scott Carleton, and Dan Collins for taking the time to share their work with the eBird community.

October eBirder of the Month Challenge

This month’s eBirder of the Month challenge, sponsored by Carl Zeiss Sports Optics, will keep get you snapping photos and recording bird sounds. Every time you take a photo or hold out a microphone, you’re creating an incredibly powerful piece of data. Media help document records, provide resources for learning and education, and also pave the way for future eBird and birding tools like Merlin Photo ID. The eBirder of the month will be drawn from eBirders who submit 15 or more eligible checklists in September containing at least one rated photo or sound. Checklists must be for observations during this month; not historical checklists entered during September. Winners will be notified by the 10th of the following month.

September eBirder of the Month Challenge

This month’s eBirder of the month challenge, sponsored by Carl Zeiss Sports Optics, will keep your eyes and ears trained upwards. As the seasons turn over in September, the movement of birds begins perhaps the best part of a birder’s year: migration. Whether you’re enjoying a northern autumn or an austral spring, things are happening! Migratory restlessness may result in local movements of 10s of kilometers, or herculean journeys that take shorebirds from the Arctic to the edge of the southern continents. The most amazing part of all of this is that you can witness it, wherever you are. The eBirder of the month will be drawn from eBirders who submit 15 or more eligible checklists in September containing at least one “Flyover" code. Checklists must be for observations during this month; not historical checklists entered during September. Winners will be notified by the 10th of the following month.

eBird Android──自動追蹤你的賞鳥路線

最近,Android版本的行動eBird有個重大進展:自動追蹤你使用eBird時所行進的路線。每次你從eBird Android開啟一份新的紀錄清單時,你可以選擇是否要讓GPS記錄你的行進軌跡。這項功能若開啟,會自動記錄你的行進時間和距離──所以你只要專心賞鳥就好了!這絕對是eBird發展史的新章,替未來一些超棒的新工具開啟了無限可能:相關研究可利用你實際的賞鳥路程而改善研究結果,eBird資料輸出可以針對每份清單顯示確切路徑,諸如此類。此外,這功能讓你的賞鳥過程更為輕鬆。立刻就啟用eBird Android吧!

在紀錄清單上更改鳥種

你是否曾經上傳照片或錄音檔到紀錄清單,之後卻發現認錯鳥種了?這時你得從eBird網頁端刪除那張照片,再重新上傳到正確的鳥種上。或者,紀錄審查員通知你清單上有錯誤,你要更改,這也頗麻煩──尤其當你要把原來的備註、繁殖代碼、年齡性別資訊等改放到新的鳥種時。我們在此宣布一項全新、簡便的方法,從今以後更改鳥種就輕鬆許多:各位可以直接透過清單編輯頁面上的「更改鳥種」來編輯紀錄清單。首先,先到「管理我的賞鳥紀錄」頁面,再找出想編輯的清單,點入後選「編輯鳥種清單」,就能更改鳥種。

eBird 2017 八月挑戰

本月由卡爾蔡司運動光學所贊助的 eBird挑戰  ,要來鼓勵你在天氣炎熱的八月多出去走走。如果你能在八月上傳 31 份以上符合條件 的紀錄清單,就有機會被抽到。中獎者將於下個月10號前通知。八月其實是個有趣的月份,如在寒帶繁殖季將要結束,但卻是南半球春天快要開始的時候。許多鳥開始在棲地間遊蕩,更有不少水鳥和部分小型陸鳥已經開始遷徙,趕快出門看看可以發現些什麼吧!

新登場!西半球eBird動態展示

每當我們外出賞鳥,並且提交紀錄到eBird時,就像是替全球鳥類的時空間分布拍張即時小照片。eBird有個宏大的願景,就是從這些小照片來拼湊出全球鳥類豐富多樣的時空分布樣貌。而這些鳥類分布圖像的貢獻,已經開始揭露出鳥類與環境之間的複雜關係,此外,隨著季節更替,我們也開始了解鳥類在地球上散布和遷徙的循環是如何進行。有鑑於此,我們很高興跟各位分享我們的2017 STEM模型,這是「eBird出現地圖」多年來蛻變、進化之後的成果。STEM(Spatio-Temporal Exploratory Model,時空探測模型)是一種「物種分布模型」,由康乃爾鳥類研究室的統計學家和研究人員特地為處理eBird資料所發展而成。

eBird影音名錄要你好看!

你是否想過,有沒有一份電子圖鑑,能讓你查看世上任何熱點或地區的鳥種?好康報你知,那就是我們的「eBird影音名錄」啦!最猛的是,這裡頭的資訊都來自你所提供的紀錄喔!我們從麥考利資料庫中,挑選評分最高的照片跟錄音,結合eBird相關數據,呈現鳥種出現的季節變動,以及一種鳥在該地區最後一次被記錄到的日期。成果便是:能夠提供最適切資訊的區域鳥況概覽。你想讓你拍的照片成為該區的最佳影像嗎?把它放上你的紀錄清單就對啦!想要看看影音名錄到底長啥樣,可從探索區域或探索熱門鳥點頁面來搜尋某一區域或熱點。在鳥種清單的最上方,你會看到一個新的分項標籤,「影音名錄」。這裡有個例子可查看。

Bird Academy giveaway: How to Identify Bird Songs

As summer winds down across much of the Northern Hemisphere, there’s still a lot of bird song to be heard. Want to improve your audio birding skills?
