Quick answer
Cockatiels feed on seeds, grains and plants, adjusting with season, age, and what is abundant in Open scrubland and wetlands (wild). That label is a preferred pattern, not every item an individual might sample.

Cockatiel diet overview
Cockatiels (Nymphicus hollandicus) are best summarised as Herbivore (seeds, grains, plants). Anatomy and habitat (Open scrubland and wetlands (wild)) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How cockatiels find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Cockatiel role in the food web
As herbivores shaping plants and seeds, cockatiels move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild cockatiels. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
The expressive crest
A cockatiel's mood can be read from its crest. When the bird is relaxed the crest sits at a gentle angle, when it is alert or excited the crest stands tall, and when it is frightened or angry the crest flattens against the head. This visible body language, along with their gentle nature, helps make cockatiels easy and rewarding to keep.
Whistling and sounds
Cockatiels are better known for whistling than for talking. Males in particular learn melodies and can whistle catchy tunes, and many mimic household sounds such as phones and microwaves. While some learn a few words, their clear, musical whistles are their standout trait.
