Whatever happened to Radaghast?

Yet he was chosen by Yavanna. Thus it is little surprise that he mostly protected her creatures. I can't see how he could be blamed for it.

Another indication of somehow different mission is the fact that Radagast remained in ME after Sauron had been brought down. Gandalf regarded his mission as terminated (he was the enemy of Sauron), but not Radagast. He remained and continued his task.

First and formost, Radagast was the first to give warning against the nazgul when he became aware that they had crossed the Anduin. He acted without delay: he left Rhosgobel and went (flew) to report to Saruman, the head of the Order. He also consented to go look for Gandalf to warn him. But for it, Gandalf would have remained oblivious of the danger. It was not Radagast's fault that Gandalf got trapped in Orthanc and that Butterbur failed to send the letter to Frodo. What is important is that Rhadagast was willing to forget his birds for a time and do his duty against Sauron.
