"El pájaro bebe agua."
Translation:The bird drinks water.
The accent ´ above vowels is used to indicate stress or to differentiate between words (él vs. el). And when you see 'ü' it means that you should pronounce the letter instead of ignoring it, and is seen after 'g' or 'q'. http://en.wikipedia.org/wiki/%C3%9C#U-diaeresis can explain it a bit more.
