Here is a close up of ware to stand when trying to catch the condor. The arrow points to a tinny small line that seems to mark a fairly good target area for standing. With the red dot on the walking action, click on this line and Graham should move to a good position to try and catch the condor.
Catching the condor seems to be more an issue of timing that positioning. Timing isn't something I have found a perfect way of mastering. It seems that I am most often able to grab the condor when it is almost above Graham when I jump. It is helpful to slow down the game speed when attempting to this also and will give you more time to watch the condor's position. (Any better suggestions please see the about page and send me an e-mail).
