On many species with bright, colourful males (Red-flanked Bluetail, Narcissus Flycatcher, Blue-and-white Flycatcher etc) the contrast between replaced adult-type very colourful feathers and retained, usually worn, brownish juvenile feathers in the wing can be obvious.
在许多公鸟色彩明亮鲜艳的鸟种(蓝尾鸲，黄眉黄鶲，白腹琉璃等)身上，已替换的成鸟型态非常鲜艳的翼上羽毛，和还留著，通常已磨损，带棕色的幼鸟羽毛，其对比是很明显的。

They also moult more or less continuously from juvenile through to adult plumage, so can be very variable at any time "in between".
而且它们从幼鸟一直到成鸟持续地在进行换羽，所以我们看到的很可能是介於两种羽色之间的过渡阶段。

Here we show that American coots, Fulica americana, can recognize and reject parasitic chicks in their brood by using learned cues, despite the fact that the hosts and the brood parasites are of the same species.
被巢寄生鸟当作目标的很多鸟类已学会拒绝寄生鸟的卵，但它们却很少有排斥寄生鸟的幼鸟的--如果这些幼鸟得以孵化出来的话，即便这些幼鸟与它们自己的幼鸟在大小上的差别显而易见。
-
Even after the baby is hatched, it's dad who keeps the baby in the brood pouch.
即使在幼鸟孵出后，爸爸也会把幼鸟放在育仔囊中。

His experiments with young indigo buntings showed not only that the star patterns have to be learned through exposure to the skies at an early stage in life, but individual birds may learn to fixate on different reference stars in the small group of constellations that lie over the pole.
他对靛蓝色的巫鸟雀的幼鸟所作的实验表明，不仅仅是星星的形状需要鸟儿在出生后的幼鸟阶段在空中飞行时学知，即使是长大的鸟也需学会注意极地上空的那一小群星座中的各种不同参照星。
-
Some birds, for example, always feed the largest chick in the nest, while others chose the hungriest or feed chicks at random.

An all dark juvenile marsh harrier, or a juvenile or immature with a paler head, full eye-stripe (reaching from the nape-sides through the eye and across the lores), lacking a pale rump, pale patches on the upperparts away from the marginal coverts, or extensive pale on the under sides of the primaries, barring or streaking, can be safely identified as a WMH .
依据以下几点才能被鉴定为白头鹞：所有暗褐色的鹞属猛禽幼鸟，或拥有过眼纹及浅白色头部的鹞属猛禽幼鸟或亚成鸟；没有浅色腰部；身上具有白斑，而翼上覆羽没有；或初级飞羽的基部具大片的浅色区域、横纹或斑纹。

The result indicate the optimized clutch size is 11 in the nest box by analyzing the reproductive parameter such as hatching period, hatching rate, feeding period, fledged rate, fledgling mass and number fledged of 10 and 11 clutch size.
在育雏前期，亲鸟喂雏频次与窝雏数有一定的正相关关系，而在育雏的中期和后期没有这种关系，说明在育雏的中期和后期亲鸟会最大限度的提高它们的繁殖投入，以保证幼鸟的最佳数量和质量，同时尽量缩短育雏时间，降低被捕食的风险。
-
This work indicates that the correlation between the clutch size and reproductive success of Great Tit is remarkable.
对窝卵数为10枚和11枚的孵化期、孵化率、育雏期、出飞率、幼鸟离巢体重、出飞幼鸟数量等繁殖参数比较结果表明，人工巢箱条件下，大山雀的最佳窝卵数为11枚。
