There are thousands of different kinds of birds and this is not enough for identification.
It would help to know: What kind of bird? How large? In what country was it found? What type of habitat? What sound did it make?
Check your field guide for yellow warbler.
canary

An eagle. I think parrots too.
yellow-rumped warbler
Possibly a Yellow-bellied Sapsucker.
The answer is a Western Kingbird.

A mallard is a bird that has an iridescent green head and brown on the body. The ring necked pheasant is another bird with a brown body, and an iridescent green head.
I think it's a parrot.

Yellow big bird
Interesting. You are the fourth person to ask about this bird that I've seen so far. It is a Northern Flicker, specifically the "Yellow-shafted" morph, nicknamed "Yellowhammer". It is a species of woodpecker.
