Why are the C. Sparrowhawk & B. Goshawk so similar?

One difference between the two species is that the Sparrowhawk does not have a distinct immature plumage, moulting directly from juvenile to adult plumage.

I'd love to know the answer to that. Also with the superficially very similar Black-shouldered Kite and Letter-winged Kite, why so similar when perched, and why the different underwing pattern and eye marking?
