The Whinchat's delicate weight (16-22 grams) highlights its lightness, which is often compared in context to what common item?
Answer
Less than that of a standard AA battery
The bird's weight is cited as being very light, typically ranging between 16 and 22 grams. This specific range is used to illustrate the extreme lightness required for the bird to successfully complete its extensive annual migrations between breeding and wintering grounds. The comparison drawn directly highlights this lightness by noting that its mass is generally less than the weight of a standard AA battery, emphasizing the minimal load the small passerine carries during flight.
