Marine Whelk Snails Are The Ocean’s Daddy Day Care, But Less Awful
Marine whelk snails carry their young on their back, toting their eggs
around for weeks after mating. The notion is not actually that uncommon
under the seas — male pipefish and seahorses are also known to take on
surprisingly active paternal roles, like gestating their own young. However,
a recent analysis of marine whelk eggs by researchers at UC Davis showed

The BBC reports that a new study on zebra finches has discovered that
same-sex pairings of the colorful birds not only exist but they also
participate in mating behavior just like their heterosexual counterparts.
Apparently the highly vocal birds sing to their mates in order to strengthen
the bond between them and this behavior is found in both he... 阅读全帖 |

发帖数: 12425 | 45 我也淆着认鸟，无奈一来我这人没耐心，二来网上搜索能力差（其实是因为没耐心），
认个鸟得花老大半天功夫，有时还一无所获，只能求救动物园的童鞋们。幸运的是，这
个鸟我很快就在网上发现了名字和图片，House Finch，头和胸前有红色羽毛的是雄鸟
，全身都灰了吧嘟的是雌鸟（再次证明自然界中雄性比雌性华丽）。你们帮我确认下我
的结论对不？
下面两张图，右下角的一只是Male House Finch吧，傍边和上面还有雌的，其余的好像
有Female American Goldfinch，对不？
下图中是不是House Finch和American Goldfinch,且都为雄性的？（发现背景有一只模
糊的小蜂鸟。）
下图中有四只鸟，House Finch和American Goldfinch，右上的那只很模糊，不知是个
啥（White Breasted Nuthatch，典型的倒挂扬头姿势，感谢李冰冰）。

Lesser Goldfinch。如何分辨American还是Lesser Goldfinch这个问题一直困扰着我，
所以手上有几张照片也总是没贴。我看鸟书的时候脚得这两种Goldfinch有些区别，可
是一对照自己的片子就晕菜了。有时连性别都判断不出来，倍儿受打击。比如书上画的
十月到三月间的雌、雄American Goldfinch就很类似，虽然羽毛明暗有区别，但照片往
往受到当时光线的影响，就不易判断了。
请问各位童鞋，有没有窍门区别下面照片中：
（1）到底是American还是Lesser Goldfinch？
（2）性别是雄是雌？
关于House Finch的旧帖在这里（后面有一张Male Lesser Goldfinch）：

in a typical primate social system,
the ranking of female is very stable and transfer from mom to daughter.
a tiny infant monkey from a high rank mom could abuse other monkeys already.
you could look up some documentary.
The group has a king, the alpha male, which typically only could hold the
position for couple years and always end up in painful death.
male ranking is not stable. they typically come from outside and join the
group to survive. and to ... 阅读全帖 |
