Two
The small size of ruby-throated hummingbird eggs is directly related to the fact that the female typically lays two eggs in a single clutch. This is because the female hummingbird’s body is only able to produce a limited number of eggs, and the size of the eggs is constrained by the size of her body. If the eggs were any larger, the female hummingbird would not be able to lay as many eggs, and this would reduce her chances of reproductive success.
In addition, the small size of the eggs allows the female hummingbird to incubate them more effectively. Hummingbirds are very small birds, and they do not have a lot of body heat to spare. If the eggs were larger, the female hummingbird would have to spend more energy incubating them, and this could reduce her chances of survival. By laying small eggs, the female hummingbird is able to conserve her energy and increase her chances of survival.
