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).
Role of Hormones Antidiuretic hormone (ADH): Controls reabsorption of water in the blood. (more ADH, more water reabsorption) Made in the hypothalamus but stored in and released from the pituitary gland in the brain. Increases the permeability of the walls of the distil tubules and collecting ducts to water.t is produced in the hypothalamus and secreted from the posterior pituitary gland. Aldosterone increases the reabsorption of sodium ions into the blood in the loop of Henle and distal tubes.
