<human>:  What are the differences between parakeets, cockatiels and lovebirds?
<bot>: The main difference between parakeets, cockatiels and lovebirds is size. Parakeets are the smallest of the three, typically about 7 to 8 inches long. Cockatiels are slightly larger, measuring 11 to 14 inches, and lovebirds are the largest, usually around 6 to 8 inches. Parakeets tend to be the most popular choice for first-time pet owners due to their relatively low cost and ease of care. Cockatiels have unique feather patterns and may be more outgoing than parakeets. Lovebirds are known to be very active and social birds and may be more interactive than other parakeet species.
