first chase it so it is in the bottom-left corner, by the rock. That's right where you want it. See those sticks? The piles of sticks that make noise when you step on them? Walk across both piles and watch the Farfetch'd listen to the noise, turning which direction it's looking.
When it's down there, step on the bottom set of twigs, the ones directly to the south of the rock it is by, then carefully walk to the right, avoiding that other set of twigs and go in from the other side of the clearing so you'll wind up behind the Farfetch'd. Press A by it when you're behind it and it's facing away and you'll catch it, bringing it back to the dude from earlier.
He expects you to go get the other one he lost. It's farther back in the forest. Head east, pick up the Revive along the way, and head for the next Farfetch'd. This patch is very similar and it will seem like the last one you just did, but it's actually a little more interesting due to where the twigs are placed.
To bag this Farfetch'd, lure it to the top-right corner (it won't go in the area where the two twigs are, so don't worry). When it's there, walk over and step on the set of twigs directly to its right. That will cause it to look right. Then walk up into the corner, carefully avoid the northern-most twigs, and then walk up so you're behind it. That's it
