Can birds see color?

Cards are items that appear in Angry Birds 2. When you play a level, the first three cards appear at the bottom left of the screen with the other cards on the main deck faced down. The cards are the birds or spells that you will choose for the next shot. Choose one by tapping the first three cards, just like choosing the birds in Angry Birds Stella’s pig sightings levels. However, it is used to attack the pigs. If the player runs out of them & there’s still pigs remaining, they will either watch a video for a free bird once or be charged with   × 60 for additional 3 cards for the first time, the price will increase to 180 for the second time & will double every time you revive. after the fifth revived the price stops doubling, If you don’t revive the level is failed and you lose a heart.
