NASA’s space program has nothing on Mother Nature when it comes to lightweight structural engineering and powerplants. They are very, very highly optimized critters.
And adult ostriches are too heavy to even pick up without help. I get your point.
Since I was responding to a comment about sparrows, I thought adding a “flight-capable” qualifier to my statement about birds was a tad too technical (read anal retentive) even for my usually over-verbose over-precise prose.
Yeah, I’ve seen a red tailed hawk, which is a lot smaller than an eagle, carry a squirrel it had just killed up into a tree for a peaceful lunch. (I was in my car, in a parking lot, and for a moment i was afraid it was going to land on my windshield. The moment was memorable.) And I’ve seen bald eagles carry a fish to give to their young. I would have thought a coconut (about 7 pounds with the husk, per Wikipedia, but it varies) would be around the limit of what a large eagle could carry, but if you could somehow motivate the eagle, i think it could do it.
Their talons are incredible strong. An eagle could easily grip the soft husk of a coconut.
