"Aery is a peaceful exploration game from the perspective of a little bird who decided to discover the world. Calm down from the hassle of your daily life, experience the feeling of flying and immerse into beautiful and atmospheric landscapes." - microsoft.com
Full credit for the 100% video walkthrough goes to Achievement Land.
The object of the game is simple; fly around each level and collect feathers. The controls are basic; controls the flying and rotates the camera. and lets you do barrel rolls. Also, all of the achievements are story-related so by completing the game you earn the full 1000.
Most of the feathers are out in the open and easy to find, but there are some that are obscured from view or blend into the background making them difficult to see. Some of the levels are more expansive than others too, so you may be searching for a while. If you have any issues finding feathers, you can always refer to the video in "A Journey Ends".
If you crash, you are placed back at the starting position, but you retain all the feathers collected up to that point. Luckily, the flying mechanics are simple to learn so you shouldn't have much trouble. Also, there is no way to speed up or slow down; you travel at a consistent speed, so if you miss collecting a feather, circle back and try again.
Aery is probably one of the most relaxing games you can play on the Xbox One. Enjoy your 1000!
