It is known that homing pigeons tend to avoid flying over the water in the daytime, perhaps
because the downdrafts of air over water make flying difficult. Suppose a homing pigeon is
released on an island at point C , which is 3 km directly out in the water from a point B
onshore. Point B is 8 km downshore from the pigeon’s home loft point A. Assume that a
pigeon requires 1.28 times the rate of energy over land to fly over water. Toward what
point S downshore from A should the pigeon fly in order to minimize the total energy
required to get to home loft A ?
