Yes. A princess parrot is a long-tailed, ground-foraging Australian parrot whose condition can slip quietly: she may still fly to the top perch, call in the morning, and pick through seed while slowly carrying less muscle over the keel bone. A simple health and weight log turns that vague impression into evidence, showing whether a lighter reading is a single odd morning or the start of a pattern worth investigating.
Setting a trustworthy baseline for this bird
Weigh your princess parrot the same way, at the same time, on the same day each week. First thing in the morning, before the feed goes in, gives the cleanest comparison, because a crop full of seed and blossom can shift the reading enough to hide or invent a change. Use a perch mounted on a small scale if she will step onto it calmly, and record the result alongside a quick keel check: run a finger gently along the breastbone and note whether the muscle either side feels full, flat, or shrinking. Add her moult stage, because a heavy moult can nudge weight and energy without anything being wrong.
What to write down besides the number
Weight alone tells only half the story for a princess parrot. Note what she actually ate rather than what was offered: this species enjoys sorting through seed on the ground, scattering husks, and favouring a few items while leaving the rest, so a full-looking dish can hide a shrinking intake. Record droppings, time spent on the aviary floor, willingness to fly the length of the enclosure, breathing after flight, and any tail bobbing at rest. Note new foods, a change of aviary mate, cold snaps, and egg laying if she is a breeding hen, because those details later explain readings that otherwise look alarming.
Reading the trend like an owner, not an alarm
Look for direction over several weeks rather than reacting to one entry. A princess parrot that holds steady, eats with interest, and flies strongly is showing you a healthy pattern even if individual mornings wobble slightly. Concern grows when the line drifts the same way week after week, especially alongside quieter behaviour, more time sitting fluffed on the floor, or droppings that change in colour or volume. Because princess parrots spend so much time low down, also note any exposure to droppings from wild birds or damp, soiled ground if she lives outdoors; that context belongs in the log, not in your memory months later.
When the log says to call the vet
Book an avian vet promptly if the downward trend continues across consecutive weigh-ins, if she stops flying to high perches, breathes with an open beak after mild effort, or passes very scant droppings. Take the log with you: a dated run of weights, foods, and behaviour notes lets the vet judge how fast things changed and what else was happening at home. Do not wait for her to look obviously thin, because by the time a long, slim parrot looks wasted, the loss has usually been building for a while.
