Yes — and this species is exactly why logs exist
You should keep a health and weight log for your Bourke's parrot, because few pet birds give you less to go on by eye. A bird that feels unwell typically does the Bourke's version of coping — sitting a little quieter, eating a little less at its dawn and dusk feeds, spending a little more time on the cage floor — and every one of those shifts is easy to wave away in a busy week. One page of weekly weights and two-line daily notes turns 'he seems a bit quiet lately' into a visible trend with dates, and that trend is often what gets a small bird to an avian vet while help is still simple.
Weighing a small grass parrot without a battle
Weight is the log's backbone, and for a bird this size the method matters more than the equipment budget. Use a small digital scale that reads in grams and a perch or a light container the bird already knows, and weigh at the same point in the routine every time — before the morning feed is the most consistent moment, since a crop full of seed at dusk and an empty one at dawn are not comparable numbers. Weekly is a sensible rhythm for a healthy adult Bourke's; step up to every few days during a moult, after any illness, or when a bird is new and still settling. Record the number exactly as read rather than rounding it into reassurance, and note beside it anything that explains a wobble — a heavy bath morning, a disrupted night, a new seed mix being picked over rather than eaten.
What else belongs on the page beside the weight
Give the log a few more columns, kept deliberately light so the habit survives. Appetite: did the bird eat its usual amount at both active feeds, and did it take favourite items or leave them — a Bourke's refusing a treasured spray of millet is a louder statement than any squawk. Droppings: note changes in amount, colour, or wateriness that persist beyond a day of watery foods or a bath, described plainly rather than diagnosed. And condition events: moult progress, any fall or hard landing, a new bird or pet in the house, a room move, and every vet visit with its outcome.
Turning entries into a vet threshold you will actually use
Decide your call-the-vet triggers while the bird is well, and write them at the front of the log. For a Bourke's parrot, sensible triggers include a weight slide that continues across two or three weigh-ins, especially paired with reduced eating; a bird sitting fluffed on the floor rather than a perch through an active period; droppings that change and stay changed; any breathing effort, tail-bobbing, or discharge around the eyes or nostrils; and any day the bird does not eat at all. Those signs in any small bird warrant a prompt call to an avian vet rather than a watch-and-wait week, because little birds run on fast metabolisms and decline on the same schedule. When you call, the log answers the vet's first questions — when did the weight turn, what changed, what has the bird eaten — accurately, instead of relying on a worried memory.
Keeping the log where it will be found
A log kept in a kitchen drawer gets lost between keepers; the value compounds when everyone who feeds the bird can see and add to it, and when it travels to the vet instead of being summarised from memory in the car park. When the record lives in KinsLe, the Pet Passport holds your Bourke's weights, notes, and veterinary history in one portable packet that is ready for a vet visit, a boarding stay, or a sitter's handover without any last-minute gathering.
