Bird's engineering

續鳥媽媽意志的故事。。。
Continuing the 'Bird mom's spirit' story...

話説我堅持不讓 Steve 拿掉鳥再銜來的小枝後，我們看到兩、三隻鳥不停飛來飛去。
我們不知牠們是爭着這地盘還是協助築巢。
不過，我想牠們两天内就完工。(前兩天的大風雨可能延誤些牠們的工程。)

After I stopped Steve from taking away the sticks, we saw two or three birds keep flying to and from the nest.

We were not sure whether the birds were fighting for the place or cooperating to build the nest.

However, I think the birds finished the work within two days. (Project might have been delayed due to the stormy weather the last two days.)

你看，鳥窩做好了。
鳥真聰明，她建立了家。
牠們有讀工程學術嗎？
Here, you can see the nest is done.

How smart the bird is, she built the home.

Do they study engineering?
