A bird that drinks more than normal water will have slightly more watery discharges. One of my 2 birds seems to enjoy taking drinks of water, and it is reflected but hes always was a big water drinker hes doing great 6 1/2 years. I give them ro water with liquid vitamins. Be careful with bottled water, there is microplastics in every brand.
My 10 year old budgie died today. Was preening and eating yesterday but silent for last 3 days. Was also flying up to top of cabinet. Night before he died he went into cage by himself as normal and slept most of the time on last 2 days. Fell off perch this morning to bottom of cage but still breathing for an hour before passing
