Do parakeets like nectar

It depends on their species.

The term "parakeet" is used to describe a medium-sized parrot. A "parakeet" itself is not a species.

Some parakeet species are:

• Alexandrine Parakeet
• Budgerigars
• Derbyan Parakeet
• Eastern Rosella
• Indian Ringneck Parakeet
• Plum-headed Parakeet
• Quaker Parakeet
• Regent Parakeet

And many more.

In general, many species of parakeet do enjoy nectar and eat it as part of their diet in the wild. However other species are indifferent and will either like it or hate it.

If you'd like to know the answer for a specific species of parakeet, please re-ask the question.
