Selective Eating Is the Cockatiel Giveaway
A cockatiel fed too much becomes a food critic, because it can afford to eat only the pieces it loves. Look at what remains in the dish at day's end. If the sunflower seeds and other rich pieces are gone while pellets, grains, and plainer seeds sit untouched, your cockatiel is not eating the balanced diet you bought; it is eating dessert first, every day, and the total volume lets it skip the rest.
Serve a measured portion and watch the pattern change. A cockatiel that gets a set amount in the morning works through more of the mix by evening, and its interest in vegetables and cooked grains usually improves once easy seed stops being endless.
The Keel and the Weekly Weigh-In
A cockatiel's keel check is easy once handling is routine. With your bird perched on one hand, stroke down the center of the breast with a fingertip. On a cockatiel in good shape you feel the keel as a clear ridge with firm muscle sloping away on both sides. If the ridge feels buried, with the breast plump and rounded like a little pillow, fat is padding over the bone.
Weigh your cockatiel on a gram scale each week, same time, ideally before breakfast. Cockatiels hold their weight within a narrow band when feeding matches activity, so a steady climb across several weeks is meaningful evidence. Write the numbers down; a trend you can see beats an impression you argue about.
Table Food, Treats, and the Second Breakfast Problem
Cockatiels are social eaters, and the family table is where portions unravel. A cockatiel that gets seed at dawn, a share of toast at breakfast, a treat stick at midday, and training treats in the evening has eaten four meals designed by four different logics. None of those people overfed it alone; together they doubled its day.
Notice crest and behavior as rough gauges. A cockatiel that begs constantly, screams toward the kitchen at family mealtimes, and still has food in its own dish is not hungry; it is habituated. Redirect that social appetite into being with you away from food, with a foot toy or a shower perch instead of another bite.
Flight, Whistling, and Willingness to Move
A fit cockatiel flies to you, lands with control, and spends its out-of-cage time walking, exploring, and whistling. An overfed cockatiel increasingly chooses to be carried, flies shorter distances, and lands with a thump and a moment of open-beak breathing. Those changes creep in slowly, which is why comparing this month with last month matters more than judging any single day.
Ground time tells the same story. Cockatiels evolved to walk grasslands picking at seed heads, and a bird that still bustles around the floor investigating is using its body as designed. One that sits where you put it, waiting for food to arrive, has had the foraging worked out of its day.
When a Cockatiel's Appetite Change Means the Vet
Contact an avian veterinarian if your cockatiel gains weight despite measured portions, breathes hard after mild flights, or you feel a soft swelling along the belly. A cockatiel that stops eating, drops weight quickly, sits fluffed with droppings stuck to its vent, or regurgitates repeatedly needs prompt care, because in birds a lost appetite is a symptom, not a phase.
Bring your portion and weight records. For a cockatiel, a month of weekly weights tells a veterinarian more than a worried guess, and it separates a feeding fix from a medical workup.
Sharing the cockatiel's treats and portions through KinsLe Care Teams stops the second-breakfast problem, since each family member can see what has already been fed and when.
