The photo shows the red tip of the feather, which forms red regions at the tip of secondary feathers of the cedar waxwing.
This is the shaft of the feather called calamus.
The barbs at the lower portion of the vanes lack barbicels which hook onto barbules. The barbs are not interlocked.
The upper portion of the shaft where vanes are attached, is called rachis. The vanes consist of barbs that run parallel in regular intervals.
Barbules are attached to the barbs. The barbs are interlocked by hooks, or barbicels. The photo shows the hooks and how they attach to barbules.
The photo shows barbules that cross the barbules of the adjacent barb.
The hooks, the barbicels of the barbules are shown in the photo below. These hooks make it possible to interlock the barbs and form the planer vanes.
Cedar waxwings belong to Bombycillidae family, order Passeriformes. Click the following link to go to List of North American Birds page.
