So, I can see you used the GM guidelines for monster creation, the numbers are overall in the normal ranges. Let's look at some details then.
Nitpick: You wrote Initiative instead of Perception.
AC is moderate, HP is low, and saves are high/moderate/low - overall this makes the creature a bit fragile.
As for attacks, you used the Moderate to hit and Moderate damage.
The buzz-by attack is probably supposed to work with its fly speed, but technically speaking, a Stride is only land movement. You might want to look at the Zephyr Hawk for how you could word the ability for flying.

Overall, I think you might have lowballed this monster a bit. It has only moderate offense, and is a bit weak defensively. You can probably afford to make it a bit more powerful in one area.
You could use the Base Roadmaps (GM Core p. 115, or GMG p. 59) to figure out a good combination of strong and weak points.
Does the revised creature above look more in line?
