Intriguing gift-passing behaviour was noted today as two adult Waxwings passed food to each other. In BWP v.5, page 498, there are some exact illustrations showing what has been photographed below. The female is the lower bird accepting the berry. It is fairly obvious that there is some serious pair bonding happening. After reading the text and then re checking the photo's, it seems that many of the images are actually showing other forms of ritual bonding, eg, the erect crest of the male, fluffing of the breast feathers, fluffing and ruffling the rump feathers, extended neck, the female quivering her wings and the pair sidling along the branch towards each other. The lower photo shows the male ruffling his rump as she preens.
