万一雌鸟不小心死了，那么那三个鸟蛋就再也孵不出小鸟了吗。我的意思是雄鸟不会自己单独进行孵蛋吧，至少与雌鸟轮换着孵蛋还行。
这两只鸟都挺漂亮的，我还是头次看到这么漂亮的红衣主教鸟。?

别呀。雌鸟儿一定不会有事儿的。我估计雌鸟儿的肚子底下有特殊的生物活性保证孵化，雄鸟儿没有所以真不一定能孵出来。你看人工孵化的都必须在一个特殊的孵化箱里，我觉得就是仿生雌鸟儿的肚子底下的环境的。万一雌鸟不小心死了，那么那三个鸟蛋就再也孵不出小鸟了吗。我的意思是雄鸟不会自己单独进行孵蛋吧，至少与雌鸟轮换着孵蛋还行。

雄鸟儿估计没戏，还是去找虫子回来喂一家儿他可能比较在行。?

BC渐渐好了，上周长周末后商城陆续开张，我们算是reopen早的，那时只有1/4店开门，现在有2/3了，憋了两个月理发店最忙，儿子要去理个发，昨天打电话预约，好家伙最早6月初才行。
我们公司的几个男士也都剃光头了，有几位女同事都好久没染发了，满头的白发灰发的 看着一下苍老了许多。
Northern Cardinal Facts
- Cardinals get their bright colors from the pigments found in berries and other plant materials in their diet.
- Pairs of male and female cardinals remain with each other year round. Pairs usually do not stray very far from each other.
- Female cardinals are responsible for building the nests. Cardinals will usually build the nests from twigs, pine needles, grass, and other plant material.
- Cardinal eggs have an incubation period of 11 to 13 days. During the incubation period, the female cardinal will stay with the eggs and the male will bring her food.
- Cardinals will breed 2 or 3 times per summer. They will usually drive their chicks away 10 days after hatching.
- Male cardinals molt in early fall after the breeding season is over. Both male and female cardinals otherwise maintain their bright color throughout the year.
- Cardinals are not found often in forests. They prefer the edges of forests and grassland landscapes with thickets and shrubbery they can hide and nest in.
- Cardinals are fiercely territorial during the breeding season of May through August, but during the winter months when food is scarce they may flock together around a food source.
- An average cardinal measures about 8 inches in length.
- The cardinal is a very popular bird, and has been named the state bird of 7 states: Illinois, Indiana, Kentucky, North Carolina, Ohio, Virginia, and West Virginia.
- The cardinal has a distinctive crest which is barely visible most of the time, but can be raised when agitated.
- Female cardinals sing more complex songs than males.
雄鸟没有 brood patch, 所以没有能力孵化，只能觅食给雌鸟。万一雌鸟不小心死了，那么那三个鸟蛋就再也孵不出小鸟了吗。我的意思是雄鸟不会自己单独进行孵蛋吧，至少与雌鸟轮换着孵蛋还行。

A brood patch is a patch of featherless skin that is visible on the underside of birds during the nesting season. This patch of skin is well supplied with blood vessels at the surface making it possible for the birds to transfer heat to their eggs when incubating.
