Little Kitty, Big City

A technique that worked for me was to trip a human carrying food, pick up the food they drop, and then put it on the ground. A bird will soon slowly descend to eat it. Just judge your distance, hold A, and pounce.

(I also managed to catch a bird in flight by dropping down on it from a ledge as it sat on the street).

Make a human drop some bread / bagel on the ground.

Keep A pressed and wait near by.

When a bird is landing release the A button and catch the bird.

Find a bird that's out in the open and sneak towards them holding . It will prompt you with to pounce them, but wait till you get closer to jump. They should start to fly away but you'll catch them in the air. It's a little tricky, you just have to get the timing right.

This will require some timing as you need to sneak up on a bird and then pounce at them just as they are taking off or about to land on the ground. The key is to grab them while they are just above the ground. It'll probably take a couple tries to get the timing down!

Here is a full video walkthrough with timestamps in the YouTube Description (Cat-Like Reflexes @ 0:39:45)

You can get this Achievement very easilly, but first you need to learn how to catch a bird :

1 : Find a bird
2 : Hold RB to enter sneak mode and get close to the bird
3 : While in sneak mode, hold A to enter Pounce and use your left stick to adjust the lenght of your jump, release A to pounce

Note : A "A to Pounce" message will prompt when you're close enough to the birds so you can pounce them.

I suggest training on a few birds so you can build minimal action memory.

When you feel ready (this might still take a few attempts) :

1 : Run/walk in a bird's direction to scare it or wait until it takes off as you sneak too close to it, birds will come back to their take-off position after a few seconds and they won't be scared again if you're in sneak mode when they come back
2 : Aim at the sky and follow the bird and wait for it to start its landing approach
3 : Now make the camera follow the bird and wait for it to reach about a 1,5-2 meters altitude
4 : Adjust the pounce trajectory so it connects to the bird's landing trajectory (use the bird's shadow as a reference point) and release A

If this written solution doesn't help, I made a video for you :
