1 Lambert: How about we ride some Giant Eagles and fly over the mountains?
2 Mordekai: Now there's an idea! Let the Eagles do all the work!
3 Lambert: There you go. There's my contribution to this quest.
4 Alvissa: You don't know any Eagles, do you?
4 Lambert: I figured Kyros could summon them.

I don't think he means that type of Giant Eagle.

It's weird the things you find when you Google otherwise completely innocuous stuff. I had no idea this thing existed before. Yet it's the first Google hit for the phrase "giant eagle".

I was actually looking for something more like this. Or perhaps like this, which is in a sense even cooler, since it really existed.
