Would giving human-like sentience to a bird make the bird too energy expensive to fly?

If hawks or eagles (or any creature that can fly like a hawk) had the same ability to pronounce words as parrots but also had consciousness (what I mean by that is that they can scout and describe the enemy movement to their side), would that extra capability of their brain hinder their flight?

The ways I imagine it would hinder their flight:

1. The brain size would need to be larger to allow them to have speech and higher-than-normal memory.
2. The brain would require more blood adding to the very energy expensive process of flying.

If it does hinder flight, what are ways to make it scientifically possible (without magic)?
