Every Super Hero is not afraid of any challenges and... from time to time he has to take on such simple tasks as chasing a pigeon. In Marvel's Spider-Man you'll encounter a side mission "Helping Howard", which unlocks the possibility of tracking and catching missing birds.
Pigeons are marked on the map - just reach them and they will start to run away. Your task is to chase them with the help of your web, which is not that easy as it looks. The birds are fast, maneuverable and often change their flight path. Luckily, the game makes it a little easier to chase them - the pigeons leave a long blue trail behind them, which makes it easy to track them.
It is best to stick to a high position and gradually gain speed. When you are as close as possible to the bird, start dropping - when you are close to the pigeon, press L1+R1 to attract and catch it. You will be rewarded with a research token that you can spend on upgrades of Spider-Man equipment.
Note: If you lose a pigeon, open the map and try again - you have an unlimited number of attempts, so don't worry about potential failure.
