This is called exploratory biting. Birds tend to explore with their beaks, and this includes your fingers or other body parts. Your fingers are very new and interesting to birds, so they are often eager to inspect them. Young birds usually outgrow this behavior as they mature.
Correct Any True Biting
To correct bad behavior in birds, try not to get excited or call out vocally. Instead, use a frown and body language that shows you are unhappy. Speak calmly and softly in low tones to tell your bird that this is not acceptable behavior.
Birds can become overly excited if a new bird is close by and bite the nearest person. Birds may bite their owner if a human they do not like is approaching (displaced aggression). Some birds do not like the person approaching or trying to pick them up.
Many birds may bite when they are feeling playful and are over-stimulated. Amazons and Cockatoos are especially prone to "overload" behavior. Know your bird's body language and avoid trying to handle a bird that is obviously excited.
Birds do not bite because they are inherently “mean” or “aggressive,” as many people think. Most birds start biting when they are taught to be fearful of human hands. Baby birds who have not yet learned to be afraid of human hands can be touched all over without their attempting to bite.
Birds have many ways of showing affection for their partners. One way is allopreening, where a bird uses its bill to groom a mate, twirling each individual feather in its beak (like these Macaws.) Other birds present their partners with gifts like moss or sticks.
This can be a rapid, tap, tap, tap or a hard thump. Don't worry, your bird's beak can take the beating. This is typically attributed to courtship behavior. Your bird might be showing off to another bird, to a favorite toy/object, or to you.
Positive reinforcement is the best way to discipline a bird and you can do it by rewarding your bird's positive actions with his favorite snack or treats. You may also shower him with praise and attention when he's behaving well so he'll realize how he should act.
Often biting and pecking happens when the bird is being playful and affectionate.
Your parrot gives you kisses
Parrot kisses usually consist of the bird putting its beak against your face, often around your cheeks or lips. This can be accompanied by your bird gently nibbling you. Some parrots even stick out their tongues and lick their owners during a kiss.
The most common causes of aggression in birds are fear or previous traumatic experiences. These can lead to handling problems, bites, and attacks when birds are interacting with their owners and others.
In most cases, the bird is simply trying to groom its owner and may see their nails as part of their feathers or beak. However, aggression is not uncommon in parakeets as well, and biting could be a way your parakeet is exhibiting its aggression.
Few birds develop an emotional relationship with human beings, instead of attachment with other animals. They often return their feeling of love to a human. This is not a materialistic but an emotional attachment.
Vocal Bird Body Language
Singing, Talking or Whistling These are clear signs that your bird is in a happy mood and is healthy and content. Some birds may show off and do this more when near people. Chatter Soft chatter is another sign of contentment, or can just be your bird attempting and learning to talk.
This may result in aggressive targeting of the newcomer, and even objects owned or regularly used by that individual may be targeted. Some birds may be more inwardly focused and target themselves, mutilating their feathers, bird cages or toys. Other birds may become noisy or less manageable.
Parrots are very sensitive to our emotions, sometimes better than we are. Our birds are keen observers of our facial expressions, body language, tone and even energy levels and therefore we have to be cognizant of how our emotions can impact our birds.
Why do parrots open their wings? They'll be stretching out one wing and looking towards you. They may curl up the claw and stretch the leg on the same side of the stretched out wing. The parrot is saying with a movement, not words, 'Hi, pleased to see you again.
An angry bird may stretch up tall or crouch into an attack position, or it may sharply flick its tail or spread its wings to make itself appear larger and more threatening. Sound: Many birds have alarm calls and other sounds such as bill clacks or hisses that can indicate agitation and anger.
While many bird owners misinterpret birds' biting as an act of aggression, this behavior is often a sign of stress and fear. Birds will frequently bite and lunge to try to protect themselves when they are afraid.
Birds sometimes pick their favorites and neglect those they don't want. So, they might choose just one person who they love the most. That could also be the reason why they bite. They might think of other people as rivals for your affection.
