To your eagle I would choose a penguin. I heard a story once that they pick up a pebble and give it to their potential mate and if that other bird accepts the pebble they stay together for life. I never looked into it to see if it was true or not just one of those things I want to blindly believe in. Eagles are wonderful though. Very strong and steady is what I think of when I think of the eagle. I just bought my hubby a book called "even eagles need a push" learning to soar in a changing world by David McNally. I have not even picked at it because I am more relatable to the penguin, you know, but my spouse says it's been a great read so far. He is an eagle too. The fierceness of the eagle is the only thing that worries me for it among other birds. It's a predator which is rare for birds, right?! Are the eagles the only predator bird? I can't think of another because cultures are scavengers and seagulls eat sealife which is kinda a fine line for vegans so idk never heard of anyone wanting to be a seagull so doubt people think of it a strong or smart.
