Discussion
- Males are assumed to differ from females by {p_Am} only
- Body temperature is guessed
- mod_3: additional tW data; ignore guessed Wwx
- scaled functional response turned out to vary during handrearing
- mod_4: v is reduced
- mod_5: males have equal state variables at b, compared to females
Facts
- wings have the largest surface area (measured in square centimeters) of any extant bird (Ref: Wiki)
- It sometimes takes a condor one week to hatch from an egg; Condors do not have talons like eagles or hawks; their nails are more like toenails (Ref: ventanaws)
