  1. Prairie WarblerOrder: PasseriformesFamily: Parulidae

  2. Excretory System 1. Structure similar to that of other advanced vertebrates 2. Paired metanephric kidneys 3. Ureter dumps directly into the cloaca 4. Usually, wastes are immediately voided to save weight- but may be saved to use as a defense tactic

  3. Testis Testis Kidney Ureter Kidney Ureter Vas deferens Vas deferens Large intestine Coprocdeum Seminal vesicle Urodeum Proctodeum Vent Reproductively active male Non-breeding male

  4. O H H N C N H H Three Main Waste Products in Vertebrates 1. Ammonia (ammoniatelism) H Advantages ? N H Disadvantages ? H 2. Urea (ureatelism) Advantages ? Disadvantages ?

  5. O H H C N C N C C C N O N H H 3. Uric Acid (uricotelism) Advantages ? Disadvantages ?

  6. Reproductive System-male 1. Gonadal recrudescence 2. High body temperatures “lethal” to spermatozoa a. Produced at night when body temperatures drop b. Cloacal protuberance 3. Gonadal control of behavior

  7. Two views of cloacal protubrance in a male Song Sparrow, Fam: Fringillidae Cloacal protubrance in an Indigo Bunting, Fam: Cardinalidae

  8. Ovary Mature Ovum Ostium Infundibulum Magnum Kidney Isthmus Ureter Uterus Large Intestine Vestigial Oviduct Vagina Coprodeum Urodeum Proctodeum Vent Reproductive System-female
