The Barbets are Scansorial birds which deposit their eggs in holes in trees, the entrance to which is invariably drilled by the hirda themselves, though the tunnel and chamber may be merely enlarged, shaped or partly made by them out of the soft or rotten interior. In many cases the entrance-hole penetrates direct into a natural hollow, in which no further work is needed. No nest is made, nor is a lining of any sort whatsoever made for the reception of the eggs, which are deposited on the bare wood or upon such dust or fragments of wood which may have collected there.
The eggs are invariably white, generally rather long in shape and sometimes distinctly pointed. The texture is strong and smooth, but there is no gloss, though the surface is satiny to the touch.
No Barbet’s egg can, when freshly taken, be mistaken for a Wood¬pecker’s egg, or vice versa, though eggs taken a very long time previously might be so in exceptional cases.
