What is Candida in birds?

Candida is an environmental fungus that infects the bird's digestive tract. Often times making their crops smell 'sour', candida is the main reason for 'sour crop' infection in birds.  Many factors can lead to Candida as a primary infection such as contaminated water, diet (excessive sugar in food or fatty seeds that go rancid), long periods of treating with antibiotics such as Doxycycline, and a compromised immune system. Some symptoms of Candida, or sour crop, include a compacted or fowl-smelling crop, a crop full of mucus, fluffed feathers, lethargy, loss of appetite, and delayed emptying of the crop.
