Again, gemini says the bird is European Sparkling

They are European Starlings. While they might look like "just another black bird" from a distance, they are famous for their stunning, oil-slick iridescence and their ability to mimic sounds (including human speech and car alarms!).

Are they all the same species?

Yes, every photo shows the same species. In fact, looking at the branch and the background, it appears to be the exact same individual bird captured in a series of movements.

Why the color change?

The shift from bright green/purple to dark grey/black isn't a change in the bird's actual pigment—it's an optical trick called structural coloration.

The Science of Shimmer: Starlings have microscopic structures in their feathers that act like tiny prisms. They don't just "have" green color; they refract light to create it.

The Angle of Light: In the first 12 pictures, the bird is positioned so that the sunlight hits those microscopic structures and bounces directly back to your camera lens, revealing the brilliant greens and purples.

The Shadow Effect: In the last few photos, the bird has shifted its body or the camera angle has changed slightly. Because the light is no longer hitting those structures at the "sweet spot," you only see the base pigment of the feather, which is a dull, dark brownish-black.

Fun Fact: During the winter, these birds also have bright white spots. As spring approaches, the tips of the feathers actually wear off (a process called "wear molt"), revealing the glossy, un-spotted breeding plumage you see in your photos!

这是欧洲椋鸟。虽然远看可能只是“另一种黑鸟”，但它们以其惊艳的、如油彩般的光泽以及模仿声音的能力（包括人说话和汽车报警器！）而闻名。

它们是同一物种吗？
是的，每张照片（注：在视频后面）显示的都是同一物种。实际上，看这根树枝和背景，这似乎是同一只鸟在一系列动作中被捕捉到的画面。

为什么颜色会变化？
从明亮的绿色/紫色到深灰/黑色的转变并非鸟类的实际色素发生了变化——这是一种被称为结构颜色的光学把戏。

闪光的科学：椋鸟的羽毛中含有微小的结构，它们的作用就像棱镜。它们并非“拥有”绿色，而是通过折射光线来创造出这种颜色。

光线角度：在前3张照片（注：在视频后面）中，这只鸟的位置使得阳光照射到那些微观结构，并直接反射回你的相机镜头，从而呈现出明亮的绿色和紫色。

阴影效应：在最后2张照片（注：在视频后面）中，这只鸟的身体位置发生了变化，或者相机角度略有改变。由于光线不再以那个“最佳角度”照射到那些结构上，你只能看到羽毛的基础色素，也就是暗淡的深棕黑色。

趣味小知识：在冬季，这些鸟身上还有明亮的白色斑点。随着春天临近，羽毛的尖端实际上会磨损掉（这个过程称为“磨损换羽”），从而露出你照片中看到的这种有光泽、无斑点的繁殖羽。
