The Keel Test on a Bourke's Parrot
The keel tells you more than the seed cup on a Bourke's parrot, because this slim grass parakeet hides extra weight under soft pink and blue plumage. Hold your bird gently and run a fingertip down the center of the breast. You should feel the keel bone as a defined ridge with a slight slope of muscle on either side. If the ridge sits in a valley of soft tissue, or disappears entirely under padding, your Bourke's is carrying more than it needs.
Pair the keel check with a weekly weight on a small scale, taken at the same time of day before the morning feed. A Bourke's parrot whose weight creeps upward across three or four weigh-ins while its routine stays the same is eating more than it burns, even if each day's cup looks modest.
Leftovers Reveal What a Bourke's Actually Eats
A Bourke's parrot that is fed too much becomes a selective eater, because abundance lets it pick out the richest seeds and ignore the rest. Check the cup before you refill it. If the same less-loved seeds sit untouched day after day while the oily favorites vanish within the hour, the total offered is larger than the bird's real appetite, and the diet it actually eats is narrower than the one you think you are serving.
Blow gently across the cup before judging how much is gone. Bourke's parrots hull their seed where they sit, and a cup that looks half full may be mostly empty shells over very little real food. Judging by eye alone misleads in both directions, so weigh the fresh portion in and the remains out for a few days to learn the truth.
Dusk Flight and Ground Time as Appetite Clues
A Bourke's parrot is most active at dawn and dusk, and an overfed bird often gives up that evening flight first. Watch what happens when the light softens. A fit Bourke's leaves the perch, flies circuits of the room or aviary, and drops to the floor to forage among scattered seed. A bird that stays puffed on one perch through its usual active window, breathing a little harder after short flights, is showing you the cost of the extra padding.
Ground behavior matters too. Bourke's parrots evolved to walk and pick over open ground, so a bird that no longer bothers to descend for scattered food may already feel full from the cup before the interesting part of its day begins.
Portions That Suit a Bourke's Parrot
Portion control for a Bourke's parrot works best measured, not guessed: offer a set amount of a quality small-parakeet mix and fresh greens in the morning, then remove what is stale rather than topping up through the day. Scatter part of the ration on a clean tray or floor area so the bird walks and searches for it, stretching a modest portion into real activity.
Keep millet sprays and seed treats as training rewards or weekly extras, not permanent cage furniture. A Bourke's with a spray always within reach grazes rich food all day without ever feeling hungry enough to try the greens and vegetables you want it to accept.
When Extra Weight in a Bourke's Needs a Vet
Contact an avian veterinarian if your Bourke's parrot gains steadily despite measured portions, breathes with its beak open after mild exertion, develops a swelling you can feel under the skin, or stops flying and foraging altogether. Weight change in a small bird can also follow illness rather than appetite, so a bird that loses interest in food, sits fluffed at midday, or produces persistently scant droppings needs checking rather than a diet change alone.
Bring your weight notes to that visit. A short record of weekly weights and daily portions turns a vague worry into something a veterinarian can judge quickly, and it shows exactly when the trend began.
Logging each feeder's portions and your Bourke's weekly weights in KinsLe Care Teams lets every helper mark the measured feed as done, so the bird's true intake is visible at a glance.
