布谷鸟！

咕咕叫的鸟有多种，愚公没提供录音，无法判断他听到的鸟叫就一定是布谷鸟；相反，是哀鸽的可能性更大。
因为哀鸽春天求偶时，城市里四处经常听见他们没完没了的咕咕叫，我很不喜欢那种哭腔。

布谷鸟！

刚听了猪猪的帖子里布谷鸟的叫声，不是。看来是Mourning Dove。

点击此图，可听见布谷鸟（杜鹃）的叫声。

看来我春天听到的叫声是Mourning Dove，不是杜鹃鸟。

爸妈轮流孵蛋，一个值白班，一个值晚班。

无数的事实证明：
领导的眼睛是雪亮的。
以后，一定要：
听领导的话
跟妻走
多干活
少喝酒

人家说鸟你说你家里鸟人
谁理你家里都是什么鸟人

这个鸟叫声很烦人
和生猪在叫魂一样
声音还传的特别远
并连着叫好几个月

你在瞎扯蛋

是你无知。

请看：
哀鸽蛋又小又白，长度约为3厘米。雄鸟和雌鸟都会孵蛋，雄鸟从早晨到下午孵蛋，雌鸟则在白天余下的时间里和夜间孵蛋。孵化需要花费约2周时间。

多谢猪猪！看来我得从颜色入手了。
今天我家领导还说，这明显是两只鸟在孵蛋，其中一只颜色发灰。 ...

猪猪真是高手！能告诉我哀鸽雌雄怎样分辨吗？

《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.
