Honeyguides are named for a remarkable habit seen in one or two species: guiding humans to bee colonies. Once the hive is open and the honey is taken, the bird feeds on the remaining larvae and wax. This behavior is well studied in the greater honeyguide; some authorities (following Friedmann, 1955) state that it also occurs in the scaly-throated honeyguide, while others disagree (Short and Horne, 2002).
Antidiuretic hormone (ADH): A relatively small (peptide) molecule that is released by the pituitary gland at the base of the brain after being made nearby (in the hypothalamus).ADH has an antidiuretic action that prevents the production of dilute urine (and so is antidiuretic).ntidiuretic hormone (ADH): A relatively small (peptide) molecule that is released by the pituitary gland at the base of the brain after being made nearby (in the hypothalamus).
ADH stands for antidiuretic hormone, which is also known as vasopressin, and it looks like this: ADH is produced in the hypothalamus and stored in the pituitary gland. It's released from there into the bloodstream, and it affects how the kidneys work by letting them know how much water they need to keep in or get out of the body.
