So true that Ryan,a reduction in water intake will increase the down fall.This season I have decided that the birds only get fresh water anything the require will be put on their food. Here a clip from an article I've been reading. "The green, dry "folds" in the center of the garlic clove are especially pungent. The sulfur compound allicin, produced by crushing or chewing fresh garlic, produces other sulfur compounds: ajoene, allyl polysulfides, and vinyldithiins.[1] Aged garlic lacks allicin, but may have some activity due to the presence of S-allylcysteine. In a rat study allicin was found to be an activator of TRPA1. The neurons released neurotransmitters in the spinal cord to generate pain signals and released neuropeptides at the site of sensory nerve activation, resulting in vasodilation, as well as inflammation.[95] Allicin is released only by crushing or chewing raw garlic and cannot be formed from cooked garlic."
