It's a hawk. It has Intelligence 2. It can tell you if there are any bipeds in that valley, probably give you a rough description of their size and shape, and estimate their numbers in terms of "one", "few" or "many". It can tell you if it saw any major structures, but it doesn't know the difference between a farmhouse and a fort.
That's the real value of being able to see through its eyes.
Birds are a lot smarter than people realize. Ravens (which have the same intelligence as hawks, D&D stat wise) have been shown to be able to tell individual apart.
Given the different types of prey and dangers that a farm vs a fort have, I think they could discriminate too.
