How To Help Birdwatcher in Life is Strange: True Colors
After leaving the pub and getting on a journey to check for Havens, you will see a park. Visit the park and you will come across a birdwatcher, struggling to find a specific bird with binoculars. Reach out to her and ask what exactly she’s been looking for. Using your powers, now you know which bird it is.
Go to the riverside, then take a turn to the left and you will find a house with some BBQ settings. That house has a big tree, and soon as you look above at it, you will spot the bird, for which the birdwatcher is struggling. Now press the triangle button from your console to interact with the bird. Rush towards the birdwatcher, tell her about the bird, and get your Bird Spotting Trophy unlocked.
