Rank the favourite foods honestly, in working order
A sitter does not need a list of everything your bird has ever eaten; they need to know what works. Write the favourites in true order of power, starting with the high-value treat your bird will interrupt anything for, which is the one reserved for training and for getting a reluctant bird back into its cage. Follow with everyday liked foods, then the tolerated ones that fill a bowl but inspire nobody. Be specific about form as well as food, because many parrots accept a nut only when it is broken into pieces, or eat a vegetable warm that they fling away cold. Note quantities too, so enthusiasm does not turn into a sitter feeding treats all day.
Add the dislikes and the hard limits
What a bird refuses or must never have matters as much as the favourites. Record genuine dislikes so the sitter does not keep offering a food the bird finds stressful, and record the individual quirks, such as a bird that guards a particular treat or one that must be hand-fed a certain item to take it at all. Then list the absolute limits in unmistakable language: toxic foods for birds including avocado, chocolate, and anything containing xylitol, plus any food your avian vet has restricted for this bird's health. A sitter should finish this section knowing exactly what never goes in the cage, without having to guess or search.
Log training as cues, responses, and current stage
Training notes fail when they describe ambitions instead of sessions. For each behaviour, write the exact cue word or hand signal you use, what a correct response looks like in this bird, the reward that follows, and the stage you have honestly reached. Target training, step-up, recall to the hand, and voluntary carrier entry are typical entries, each at a different stage. Note session length and time of day that suits your bird, and any point where progress stalls or the bird gets frustrated, because a sitter who pushes past that point can undo a fortnight of patient work in one long, pushy afternoon.
Keep the page alive between trips rather than rewriting it in a panic before each one. After a training breakthrough, update the stage the same day, date the change, and cross out any treat your bird has gone off, because favourites genuinely rotate and last season's irresistible reward may be ignored now. Leave space at the bottom for the sitter to add what they observed, since a note that the bird began offering a behaviour unasked, or refused a once-loved food, is exactly the detail you will want when you resume training yourself.
Keep it as one page the sitter sees before you leave
Combine the food ranking and the training log into a single current page, and update it after breakthroughs rather than letting it age into fiction. Run through it with the sitter while your bird demonstrates, if your bird is willing, because seeing the cue and the reward delivered once teaches more than the written version alone. Tell the sitter plainly that maintaining the routine matters more than advancing it while you are away. Delivering that page through a KinsLe Care Pass means the person feeding and training your bird works from your real favourites list and your real training stage, not from guesswork.
