There are shallow rollers, and there are deep rollers. You can’t breed two deep rollers… or their young, their offspring, will roll all the way down… hit and die. Agent Starling is a deep roller, Barney. Let us hope one of her parents was not . – Hannibal Lecter
This is such a great piece of dialogue, I have always wondered whether it is true or not. And whether it applies to “real” rollers as well or only domesticated roller pigeons. Because how would the roller know whether they’re a deep roller or not?

or whoever made all this stuff at least had a good sense of colour.
“Oleandrin and neriine are two very potent cardiac glycosides (cardenolides) found in all parts of the plant. Red flowered varieties of oleander appear to be more toxic. Oleander remains toxic when dry. A single leaf can be lethal to a child eating it, although mortality is generally very low in humans. The lethal dose of the green oleander leaves for cattle and horses has been found to be 0.005% of the animal’s body weight. The minimum lethal dose of oleander for cattle was found to be 50mg/kg body weight. Horses given 40mg/kg body weight of green oleander leaves via nasogastric tube consistently developed severe gastrointestinal and cardiac toxicosis. Cardiac glycosides that act by inhibiting the cellular membrane sodium-potassium (Na+-K+ ATPase enzyme system) pump with resulting depletion of intracellular potassium and an increase in serum potassium. This results in progressive decrease in electrical conductivity through the heart causing irregular heart activity, and eventual complete block of cardiac activity, and death.”
