In General
1. It's recommend that you use white paper towels to cover your cage bottom. They're non-toxic, inexpensive and gives you a clear view of what the bird has dropped on it.
2. They should be changed at least once a day and examined at that time, as it can tell you many things. You can see what your bird has eaten or not eaten, how his/her fecal droppings have looked during the course of the day and even find the missing piece to that toy he dissasembled.
1.Normal droppings in pet birds consist of three parts. The stool is coiled or partially coiled and varies in color from rich green to brown depending on the bird's diet. It will be green with birds on a seed diet and for birds formulated diets will reflect the color of the pellet. Certain fruits can also effect it's color...for example,beets,blueberries and other fruitscan give the stool their color.
2.The urates are a by-product of the kidneys and are usually snow white when dry. They are chalky in texture and will vary in size from tiny(as in the Parrotlet) to large and spread out (as in the Macaw). It's normal to have some transient color changes during the day and some colored formulated foods can tinge them a creamy color.
3. The urine is the liquid portion and it is usually clear. The volume of the urine will change according to what the bird is eating. You will see more after consumption of fruits and vegetables and less after pellets.
1. Watery droppings..... an increase in the amount of urine are often confused with diarrhea. The fecal matter will look the same, but there will be notably more fluid around the feces. A change in the color of the urine is also a warning.
2. Loose stool, or true diarrhea, can show up in one or two droppings due to stress, but if you're seeing it constantly throughout the day it is cause for concern. The tubular feces will lose it's shape and become mushy. Color change in the feces to bright green or black is in indicator of trouble.
3. Yellow or Green stained urates is also a warning of trouble. This part of the droppings should always be white when dry.
4. Undigested seed or food in the droppings, pale or foamy droppings and a consistent change in the volume or number of droppings during the day are also of concern.
Any of these abnormal concerns to be followed up by your local veternarian.
