Keep his world identical inside a world that is not
A house move changes everything a bird navigates by: light, echoes, views from the window, the sounds of doors and pipes, even the people passing his cage. You cannot soften all of that, but you can control the things he cares about most. His cage arrangement, his food, his toys and the rhythm of his day can cross to the new home completely unchanged, and those constants are what he will use to decide that the strange place is safe.
Resist improving his setup during the move. A new cage, new food or a new routine can each wait a few weeks until he is settled, so that only one change, the house itself, is ever being absorbed at a time.
Moving day: travel calmly, arrive first
Travel him in the travel cage he already knows, secured in the car away from loudspeakers and direct sun, with a familiar toy and food he reliably eats. If the journey is long, plan water and quiet rest stops, and keep handling to a minimum. Ideally his main cage is transported and reassembled in the new home before or alongside his arrival, so he moves from the travel cage back into his own territory rather than waiting in a strange room.
Choose his first room deliberately: the quietest room that is finished, away from paint fumes, cleaning sprays and drilling, with a corner where his cage can sit against a wall as it did before. Set the cage up exactly as it was, down to which perch sits highest and where his sleeping spot is, before he goes into it.
The first days: routine is the medicine
Feed, greet, cover and uncover at the old times. Sit with him as you did at the old house, keep visitors to his room few, and let him watch unpacking from the cage rather than being carried around a home full of open doors, stacked boxes and hazards. His appetite, droppings and willingness to vocalise are your settling gauges: a bird eating normally and calling to the household within a day or two is coping well.
When he seems relaxed, offer out-of-cage time in that one room first, after checking windows, mirrors, gaps behind furniture and any cables. Add rooms one at a time over the following days, letting him map the house gradually rather than discovering it all in one startling flight.
Watch for the delayed wobble
Some birds seem fine for the first days and become withdrawn, picky or unusually loud in the second week, once the move is clearly permanent. Return to maximum routine and quiet company if that happens, rather than introducing more novelty to distract him. Keep his favourite foods in stock through the move so a familiar diet is never interrupted by an empty cupboard in a new neighbourhood.
A bird who stops eating, sits fluffed and silent, or whose droppings change and do not recover within a day of settling should be seen by an avian veterinarian, and it is worth locating one near the new home before the move if your current practice will be too far away. Registering his new address details wherever his records are kept keeps that first visit simple if it is ever needed urgently.
Divide the bird jobs during the chaos
Moving day has a hundred tasks, and bird care gets squeezed unless it is assigned by name: who travels with him, who sets up the cage, who does the first feed in the new home. Writing those jobs down protects him from being everyone's assumption and nobody's task.
