Udyr is a very strong LATE game champion, in low level or ELO people dont think he is any strong and will underestimate him, ive seen this happen lots of times. But udyr isnt any easy champion to master, but when you have first mastered him, he is lots of fun!

The build is good for udyr, because you get Movement speed to get out and in of team fights, and damage from Ghostblade + Trinity Force gives udyr insane damage late game, and defence with Omen and Force of Natur, makes udyr very offence, but he is also very offence while he have insane amount of damage and movement speed.

: Is most needed for jungeling, it makes you jungle faster, and you can safe baron and dragon kill.

: Is needed for ganks, and survival ability, if you get ganked in jungle, you got better chance getting out of it, some people go with exhaust or flash, but thats a bad choice in my opinion.

You start with Regrowth Pendant and Phonix Stance, the best way to not get ganked and give away first blood is to go to raves at the start, smite the blue rave, and Phonix the others, then you move to wolfs, and back down to double golems, after uve finished them, you will go back to base and buy Philosophers stone, at that point you should be level 3, and move to Blue golem.

Udyr is no good earlie game, so what you will be doing is farm, farm farm farm, tell your team to play passive til you get a few levels and items up, try finish your trinity force - shurelyas reverie and your (Randious omen first/youmuus ghostblade) depends if you need defence or offence.

Now udyr is getting strong, even though your strong doesnt say that your Over powered and cant die, you are not tryndamere ^^) well try hide in the bush and get your tank to go in first, then follow your tank in and kill the squishy ones, from the side or behind. If your team got, no good tank, buy defence items first and tank for your team, go in with turtle and bear stance and keep your team mates alive, when you got your bear stance on,you do one basic attack on each, and theyr all stunned for one second and can win you the team fight, but remember after you stunned one, you cant stun that target on 6 seconds, so after you stunned, switch back to turtle as fast as you can.

Is pretty much like mid game, only now your stronger, and your tank should be stronger aswell, so you should keep line of sight from people, try hide as much as you can, and when your tank goes in, go in for the weak ones.

Im not saying this is the best way to go udyr, but its a good/ok way to build and use udyr, i use it, and i have lots of fun pwning with it :) dont quit if your first game is shitt, keep playing him! His lots of fun! trust me :)
