  1. Do Birds Drink?

  2. Evaporative Water Loss versus Body Mass Fig. 6-24 in Gill 2008

  3. Evaporative Cooling H20 (liquid) + Energy H20 (gas) California Towhee 40o F 30o F Water Loss Quadruples

  4. Obtaining Water 1: Direct Uptake

  5. Obtaining Water 2: Fleshy Food

  6. Obtaining Water 3: Metabolic Water O2 CO2 H20 + +

  7. WATER LOSS (EXCRETION) &$@%& Why?

  8. PROTEIN UPTAKE

  9. Protein Digestion: Proteases I) Pepsin Trypsin Chymotrysin II)

  10. NITROGENOUS WASTE Urea (Mammals) Uric Acid (Birds)

  11. Nitrogenous Waste UREA (Mammals) URIC ACID (Birds) • Simple Molecule • Less Expensive to • Synthesize • Less Nitrogen per Molecule • Very Water Soluble • Complex Molecule • Expensive to Synthesize • More Nitrogen per Molecule • Low Water Solubility

  12. Excretory System 1: Kidneys, Ureters • Water Resorbed to Level Just Above Precipitation Level • of Uric Acid

  13. Excretory System 2: Cloaca • Very Little Water needs to be Resorbed by Cloaca • to Precipitate Uric Acid (Avoiding an Energy Intensive Process)

  14. Excretory System: Kidneys,Ureters, Cloaca (Bladder?) Rhea Fig. 4-106 in Podulka et al. 2004

  15. Bird Droppings (= Feces + Uric Acid) Fig. 4-105 in Podulka et al. 2004

  16. URINARY SYSTEM: SUMMARY Fig. 107 in Podulka et al. 2004

  17. Avian Water Conservation: An Exception Water Excretion up to 3.5 Times Body Mass

  18. Final Thoughts . . .
