Signs of illness in birds are often quite subtle until disease is advanced. Fortunately, quite a bit of information can be gleaned from a detailed history and careful observation. View this brief slideshow for tips on the visual examination.
The crop or ingluvies is a diverticulum of the esophagus present in many but not all, bird species. The crop serves as a food storage organ, regulating the flow of food through the gastrointestinal tract. Food within the crop is also softened by mucus glands. Crop stasis is a common clinical sign in which the crop fails to empty in a timely manner…
Crop wash, also known as crop lavage or crop infusion, is indicated in patients with a history of persistent regurgitation unrelated to sexual behavior, crop stasis, crop impaction, or palpable abnormalities of the crop.
Regurgitation is a non-specific clinical sign, and it is not pathognomonic for any specific problem. Regurgitation can indicate a problem anywhere along the gastrointestinal tract or it may occur secondary to crop stasis caused by systemic illness.
