媒体文件注释

Neat donkey bray vocalization. A single raven at top of leafless oak tree make this call twice at which point a second raven flew in next to it. After making a couple more calls, they both started to do some bill wiping on the branches and remained perched together for several minutes.

观察细节

Gang of 15 flying together, bronking & doing some acrobatics. Tough boyz.
