BIRDS WITH QUEER BEAKS 
87 
of birds known as curassows, many of which 
possess curious embellishments of the beak 
which usually take the form of brightly- 
coloured and bulbous outgrowths; while in 
the puffin we have an example that indulges 
in a double form of beak. When seen in this 
country during the summer months, the latter 
bird is easily recognized by its brightly- 
coloured and compressed beak which is of 
much greater depth than length. But should 
we see the same during the winter, we might 
easily be excused if we failed to recognize 
it, for during the moulting season the brightly- 
coloured outer covering of the beak falls off, 
and reveals a small and soberly-coloured 
structure beneath which is the beak proper.
