  • There are many natural strains of bobwhite; few domesticated strains have been intentionally developed (ref: oecd2006)
  • The bobwhite is distributed from southeastern Ontario (Canada) to Guatemala and in Cuba but reaches its highest density in the eastern United States and Mexico (ref: oecd2006)
  • Body size also increases from south to north in its native range with birds in Chiapas, Mexico, averaging 129 g, whereas those in the eastern United States weigh about 172 g. (ref: oecd2006)
  • Bobwhite nest in the spring with clutch sizes of 10 to 15 eggs. (ref: oecd2006)
  • Body temperature of 38.9 in summer and 37.7 in winter - we use the summer temperature in this entry (ref: SwanWein1997)


  • The entries assumes all data are performed in the thermoneutral zone. Data from SwanWein1997 which are outside of the thermoneutral zone are not included.
  • t-N dataset: egg ripening assumed to be around 0.7 d^-1, and that material accumulated in the reproduction buffer for 182.5 days prior to experiment - this number is based on the fact that they have on average 1.5 clutches per year.
