《How to Tell Male & Female Mourning Birds Apart》
--------（哀鸽傍地走，安能辨我是雄雌？）
Mourning doves (Zenaida macroura) are elegant birds.
Although male and female mourning doves look alike, they're not identical.
1，Size Difference（个头不同）
Male specimens are generally just a tad larger than females, although the difference isn't major.
2，Color Difference（毛色不同）
Colorwise, male mourning doves are a bit more vivid and intense. The males' breast regions exhibit some pink coloration, and the highest parts of their heads are also somewhat blue.
3，Wooing Activities（求偶不同）
Physical appearance isn't the only way in which to differentiate between male and female mourning doves.
Males make big efforts to attract females, notably by lingering on perches and attempting to gain attention through making sweet cooing sounds, which are like smooth and deep cries. These vocalizations draw in female mourning doves. Boy mourning doves carefully guard their preferred perches against any fellow males who are nearby. If you hear murmuring sounds coming from a mourning dove, he's probably a male.
4，Nest Construction（铺巢不同）
Nest construction is another way in which to discern between the genders of mourning doves. Male and female mourning doves work together as teams to establish their nests, both with totally different duties that are easy to tell apart.
The males collect all of the necessary elements, whether twigs, pine needles, sticks, grass or anything else.
The females put together nests that are approximately 8 inches in width, all while the males remain on their backs, providing them with all of the required components. They generally complete their nests in more than 10 hours or so.
5，Flying Style（飞姿不同）
The way mourning doves fly offers gender clues, but only in times of reproduction. Mourning doves travel in units of three individuals, in brief "lines."
The one in the front is the male half of a mourning dove mating couple.
The bird immediately following him is a competitor for female access, another male.
The last dove, however, is the female half of the couple.
