why are female birds ornamented?

generally they aren't.  the males are ornamented to attract their female counterparts.  most female birds are camouflaged (sp?) in order to sit on the nest without predators finding them.

All I've heard is that for some tribes, partially the plains, multiple feathers is probably for multiple honers, most likely war honors. Likewise different markings on feathers and worn in different ways meaning different things as pertains to these honors.\n\nFar as I know women did not originally wear feathers. I think the feathers they had were as a fan.\n\nOr so I have heard, but don't quote me on it.

most birds only have one ovary.

still in the trees. deadwood, holes in branches etc. natural hidy holes. thats why itr is important to keep old forrests around - so the trees have little places like that for the birds

On extremely cold days many birds will roost to conserve heat. If they take to the air they expose their underwings and bodies, and the short insulating feathers under the flight feathers are exposed to the cold air, so they no longer provide adequate insulation.

Humming bird necter is red. It attracts them better than other colors. I guess it mimics flower colors.

because males MAY use them as stimulation receptors, they aren't ruled out by evolution\nso infact that are used, just not like females use them (think about it, if a male has nipples and uses them this way, then he would be able to spread his charateristic to more females thereby increasing the popularity and favorability of the trait)\nas for the question of why they there in the first place...\nits one of those characteristics that are kept when the baby is developing in the womb

I don't think they are strictly male....rather a type of penguin.  Check out the link:

I guess because guys are TURKEYS.?\nAt least chicks are CUTE and cuddly unlike weird looking turks.\n Yeah I'm not sure what's up with the whole bird thing...\nBut if you get called a chic you know why    ; )\n\nHope this makes you feel better Miss SassySara-

This is really common in the animal kingdom. There is a type of snake where in which the male performs female mimicry and allows other males to mate with it. This ensures reproductive success, as only they will fertilise the females (the other males exhausted themselves on what they thought were females). Bonobos, for example, use sex in order to establish and maintain social relationships and even perform face-to-face copulation, rare amongst primates. Members of the dolphin family (such as Orca's) rub themselves against other males. There are species of lizard that are only females (and produce only clones of female offspring), and females will mount and imitate mating. It's interesting because the lizards that are mounting are "reproductively inactive" which means that they are male-like, whereas the mounted female is "reproductively active". There are also mites that mimic females, again to ensure reproductive success. \nThese are just a few examples!

Birds fly south because it is instinct. I hope that answers your question.

Tinkerbell (though i'd prefer she'd be a little bit bigger) lol More spunky, sexier outfit :)  Never dated a girl with wings..

What a good quesiton. It is very possible that the paint may have interferred with sexual seletion during mating. It is well documented that in certain species, that mates are selected by certain physical attributes. The change in color or pattern the paint made on the seals may have confused potential mates - if sight is the main way that mates find each other. I don't know a ton on seal behavior, but I seem to recall that they do a lot of calling - which may be another way to attract a mate. So, I guess it depends on the importance of visual attraction. (Like in peacocks, there is a major differnece between males and females -males are really flashy, while the females aren't. It's all way for the male to attract females). I think in seals, males and females mostly differ by size...so, taking that factor in as well, paint may not have done too much damage. \n\nHope these points are helpful to you!

They are birds. \nThey lay eggs.

No, they dont. Birds have a different "set up" as far as sex goes. Both sexes look the same, just a single opening. This is used for both elimination and sex. The male mounts the back of the female. He twists his back end around and both openings, called the cloacals, touch. He releases the sperm into her and thats how fertilization takes place.

the male robins are brighter in color\nthe female robins duller so they can blend in to the nest better from predators

Assuming that you're in the U.S. and you're talking about the Northern Mockingbird (Mimus polyglottos), the answer is yes. Both sexes sing. Males are more vocal and louder, but females sing and imitate too. Females are at their most vocal in the fall and sing rarely in spring and summer.
