Indian Ringnecks Talk Hormones

Knock, knock.. KNOCK, KNOCK.. Who's there, Andrew? Let me think.. Amino acid derivatives! It's a group of hormones divided into groups based on chemical structure. So you're a biologist, now Andrew? No. A bird-ologist to be exact. The group of hormones include thyroid hormones, catecholamines, and trytophan derivatives. Dear god Andrew, did you brush your beak this morning? No, but when ate this morning the hormones in my digestive tract secreted in numerous amounts assisting with the function of my glucose metabolism. I quite figured as much.
