对斑马雀的视觉系统的物理特性进行了测量，斑马雀是一种眼睛横向放置的鸟。对视觉系统在啄食和求爱行为中的使用进行了研究。结果表明，眼球中心凹和光轴指向约62°方向。从头部的矢状轴。每只眼睛的视野覆盖约170度。在水平面上。在额区有大约30度-40度的重叠。鸟儿可以用双眼看到的地方；在60度的视野中有一个“缺口”。双眼最佳观察点在16.5°的矢状面上。在鸟喙下。关于运动检测，双眼(正面)视野部分的上限阈值为540度/S，单眼(侧面)部分的上限为110度/S。大多数啄食前的注视都是单眼进行的。在啄食时，没有检测到偏爱一只眼睛。在求爱的歌声中，一只雄鸟将头指向雌性。该结果与鸽子和鸡的研究结果进行了比较，并进行了讨论。
Measurements were made of the physical properties of the visual system of the zebra finch, a bird with laterally placed eyes. The use of the visual system in pecking and courtship behavior was examined. It was demonstrated that the optical axis and the fovea of the eye point in a direction about 62.degree. from the sagittal axis of the head. The visual field of each eye covers about 170.degree. in the horizontal plane. In the frontal region there is an overlap of about 30.degree.-40.degree. where the birds can see binocularly; caudally there is a ''gap'' in the visual field of 60.degree.. The point of best binocular viewing is in the sagittal plane at 16.5.degree. below the beak. Concerning movement detection, the upper threshold is 540.degree./s for the binocular (frontal) part of the visual field and about 1100.degree./s for the monocular (lateral) part. Most fixations before pecking occur monocularly. A preference for one eye during pecking was not detected. During the courtship song, a male bird directs its head towards the female. The results are discussed in comparison with findings in pigeons and chickens.
