After hearing wolves, Gandalf told them to climb into the trees to escape the wolves.
Bilbo went on an adventure with the thirteen dwarves, Fili, Kili, Balin, Dwalin, Dori, Nori, Ori, Oin, Gloin, Bifur, Bofur, Bombur, and Thorin Oakenshield, and Gandalf the Wizard was with them some of the time, too.
We do not know for sure that he did see the Lord of the Eagles again, but it could be inferred. At the battle of the Five Armies, he spotted the eagles coming, presumably led by the Lord of the Eagles. They saved the day, forcing the goblins off the mountain.
The battle of five armies comes after Smaug's death, after Thorin's 'dragon greed' almost starts a war against the elves and the men of Laketown.

Gandalf played a crucial role. It was Gandalf who warned the Elves, Men, and Dwarves of the incoming Goblins. It was also Gandalf who arranged for the Eagles to come. Without the Eagles, the battle surely would have been lost. The Eagles role was important as they freed the ledges of the Goblins, enabling all defenders to head to the gate. And also, it is speculated that Gandalf had something to do with Beorn's appearance, since he was in direct contact earlier. Beorn's swift coming and going was what won the battle.
