1.Are these two(use) right?
a. The black-faced spoonspills can use their bills to catch fish easily.
b. I want to use my eyes to watch black-faced spoonspills.
2. Or have to rewrite like these:
a. The black-faced spoonspills can catch fish easily with their bills.
b. I would like to watch black-faced spoonspills with my own eyes.
b- weird- what else would you use? It doesn't sound very natural to me.
