My comments：(歡迎打擊報複)。

1. A few typos: boom - bloom; genuin - genuine; huming bird - hummingbird

 

2. catalog of birds: "catalog" is not commonly used to classify living organisms. We can use terms such as category, family, order, class, phylum, et al. Well, it is not big deal. I majored in biology, so I can't help it.

 

3. the mother nature - "Mother Nature" (專有名詞)
