下列关于鸟类生殖和发育叙述错误的是（ ）
A．体内受精，整个发育在体外进行
B．卵黄为胚胎发育提供营养
C．晚成鸟需要亲鸟的喂养
D．发育受温度的影响
A、在繁殖季节，许多鸟类会选择合适的场所筑巢，然后求偶，求偶成功，雌雄鸟进行交配．精子和卵细胞在雌鸟的体内结合成受精卵．受精卵在雌鸟的体内就开始发育．产出后，由于外界温度低于亲鸟的体温，胚胎停止发育，需要由亲鸟或是其它鸟类孵化才能继续发育．符合题意．
B、卵黄为胚胎发育提供营养，不符合题意．
C、晚成鸟也叫做晚成雏，晚成雏出壳时还没充分发育，身体外表没有或只有很少绒羽，眼不能张开，需要由母鸟衔虫喂养．不符合题意．
D、影响鸟类胚胎发育的外界因素主要是温度，不符合题意．
故选：A
