Sentence:
When dodo's ancestors setteled on this island with abundant food,no competition from terrestrial mammals, and no predators, it could survive without flying, thus was freed from the energetic and size constraints of flight.
cited from Khan Academy's SAT practice; Science.
- Why is 'constraint' used instead of 'limitations/restrictions' ? (I looked up an saw constrain means 'to hold within' e.g the cows were constrained within the field with barbed fences).I could not incorporate this meaning into the specified context.
- Why is 'size' used , being a noun adjacent to 'energetic' an adjective.
- What does it mean by freed from enegetic and size constraints of flight? Could it be reiterated to: The birds were freed from the obligations of having to reserve energy for flying and not growing too big in size so it's harder to fly? Also doesn't it invoke pleonasm, since having greater mass would mean they'd have to reserve and expand more enegry for flight?
I apologize for the really long question. Also if I've made any grammatical errors please rectify and apprise me of it in the comments.

(a) Because that's the word the writer chose! (b) They could have put 'energy and size constraints'. (c) Yes, it means approximately what you say in your paraphrase. (Reiterate means to repeat something.)

But doesn't constraint have a slightly different meaning ? (Atleast that is what I saw from google searches) or are the three words (constraint,restraint/restriction,limitation)completely synonymous?. Also, was the '...energetic and size constraints..' improper english? My bad on part 'c', thanks for pointing it out.

The first definition of "constraint" at dictionary.com is "limitation or restriction".

Yes, "energetic and size constraints" seems wrong, for exactly the reason you give. "energetic constraints" means constraints that have energy, not contraints on the amount of energy needed.

I don’t think your paraphrase is a good one. we’re talking about evolution here, not conscious decisions made by the birds- the use of obligations and reserve are not apropos.
