Pacific Parrotlets are highly social small parrots. They can live in flocks of up to 50 individuals, and they communicate through a variety of vocalizations.

Males have vivid blue feathers on their wings, while females have more muted colours. 

Pacific Parrotlets eat a variety of plant material, including seeds, fruits, and flowers. They tend to stay in one area throughout the year, foraging in different areas to follow seasonally available foods.

They nest in tree cavities. Females lay 4 to 6 white eggs, which are incubated for 18 to 21 days. Both parents take care of the eggs and chicks.

They are considered Least Concern on the IUCN Red List with a fairly large range and stable population. They are also adaptable to human activity, so they will likely continue to thrive as human land use expands.
