True Parrots

The true parrots are about 330 species of bird belonging to the Psittacidae family, one of the two "traditional" families in the biological order Psittaciformes (parrots). The other family is the Cacatuidae (cockatoos) which are also parrots, but not classified as true parrots. True parrots are more widespread than cockatoos, with species in the Americas, Africa, Asia, Australia and eastwards across the Pacific Ocean as far as Polynesia.
The true parrot family is often considered to contain two subfamilies, the Psittacinae (typical parrots and allies) and the Loriinae (Lories and lorikeets). However, there are other systems of classification and these two groups are sometimes ascribed full family status, being called Psittacidae and Loriidae. This does not seem to be warranted however, though treating cockatoos and certain lineages of true parrots at equal taxonomic rank (but not as families) may well be so; see below for why.

Hummingbirds

Hummingbirds are birds of the family Trochilidae, and are native only to the Americas. They are known for their ability to hover in mid-air by rapidly flapping their wings 15–80 times per second (depending on the species). Capable of sustained hovering, the hummingbird also has the ability to fly backwards, being the only group of birds able to do so.Hummingbirds may also fly vertically or horizontally, and are capable of maintaining a position while drinking nectar or eating tiny arthropods from flower blossoms. Their English name derives from the characteristic hum made by their wings
Owls

Owls are an order of birds of prey. Most are solitary, and nocturnal, with some exceptions (e.g. the Burrowing Owl). They are classified in the order Strigiformes, in which there are over 200 extant species. Owls mostly hunt small mammals, insects, and other birds, though a few species specialize in hunting fish. They are found in all regions of the Earth except Antarctica, most of Greenland, and some remote islands. Though owls are typically solitary, the literary collective noun for a group of owls is a parliament.
