I've also noticed the female is quieter, less fidgety, and walks with her talons more open. The male likes to rearrange the nesting material a LOT, and walks with his talons curled up way more, way sooner when approaching the eggs, and he's just noisier, calling for his mate more frequently. The female's beak is much larger/heavier. The male has the spikey feathers on his head.
A lot of people on the (eagle) forum are confused about which is which- so that's unreliable about who was on the nest when. But, if you see them together, the larger female is quite apparent.
