A pair bond is like having a very special friend that you love and trust very much. You might like playing with other friends or toys, but this special friend is the one you want to be with all the time.
In the animal world, some animals like birds, wolves, and penguins also have this kind of special friend. It's when two animals decide to only be together, share a home, and have babies together. It's like they're married.
They take care of each other, share food, and protect the family they make together. They even have special ways of communicating, like making special sounds or movements, and sometimes they can feel what the other is feeling without even talking.
Pair bonding is very important because it helps animals feel safe, loved, and supported. And just like with people, some pair bonds last a long time, and others might not work out, but the animals will always have that special friend memory.
