我們每天晚上都要到離宿舍1.5小時車程的海灘巡邏,找巢和海龜媽媽。拾到的龜蛋會放到海灘的hatchery 裡,數數目然後整個新巢堆了蛋。因為周圍有小天敵例如浣熊、貓等愛吃蛋的小動物,因此hatchery 被四面圍封防止牠們進入。我們每晚到hatchery 查看有沒有龜仔出世,如有便把牠們放生到海裡去。昨晚有一隻龜仔出世了,但牠懶得不想動,或未瞓醒?呵護了牠一小時,放在沙上還是沒動 (但反轉牠又很醒爬),最後還是把牠放回hatchery 等待牠瞓醒才放了。 . . . Patrol We will patrol the beach where it is 67km away from our hostel every night. Searching for nest and turtle mother. If there is a nest, we will take out all the eggs , count the numbers and put them into hatchery , we create a new nest for incubation. As there are some animals like racoon and cats etc. love the eggs, the nursery has to be fenced off. Every night we will check the nests in hatchery to see if there are babies hatched. If so, we will release them. Last night we got one baby, but he is just so sleepy that it seems didn't want to leave. I took care of it for 1 hour but finally he still didnt move at all when i put him on the sand. So finally we put him back to the hatchery and wait until he is active again later. ...
今天特別環節,黃昏放生海龜BB~ 墨西哥西岸有大大小小長長的海灘,都是海龜繁殖地,但一些已變成遊客陽光與海灘的地方,就是海灘旁建了不同的酒店,因此日頭的海灘人流不絕。但在這個離hostel不遠處有個長長的海灘,也是海龜繁殖地。這裡沒有建酒店,因此也沒什麼人來。也因這樣,海龜媽媽可放心下蛋了。Red tortuguera 也在這裡建了一個小小的hatchery,由於政府不讓他們建建構物在海灘上,因此這個hatchery也十分簡樸,不過由於遊人不多,也不怕有人騷擾。 我們今天放生29隻Olive ridley 小海龜,我們每人要用沙"洗洗手", 把手上的油和味洗走。然後把牠們放到近水邊一字排開,小海龜需要在沙灘上爬爬走走,感受牠們出生地的海灘的沙和海水,這個記號會留在牠們腦海裡,直至長大成龜,大約15年後,到了可交配繁殖的年紀,牠們便會游回牠出生地附近的水域找伴侶進行交配,交配後媽媽便在某一夜晚回出生地上岸下蛋。 由於太大浪,因此龜龜都不斷被沖回上岸,要等待牠們到回到海中,我們的工作就完成了。 以後就要靠自己喇,海龜BB 加油喇! P.S. 也有研究指小海龜的記憶內有地磁標記,因此會懂得回家的路,相信遷徙的鳥和獸也是如此。 Ref.: https://medium.com/…/how-do-sea-turtles-find-their-way-home… . . . Today we are going to release babiesssss in the evening! There are many beaches along the west coast of Mexico, many of them are the breeding site of sea turtles. at the same time, many hotels were build next to the beach for tourism, at daytime there are many human activities on the beach. But there is a long beach near our hoste...
