fact that if, while the bird was saying, 6 Old — old — old —

Emotions . 
As regards emotions, it is among birds that we first 
meet with a conspicuous advance in the tenderer feelings 
of affection and sympathy. Those relating to the sexes 
and the care of progeny are in this class proverbial for 
their intensity, offering, in fact, a favourite type for the 
poet and moralist. The pining of the 6 love-bird ’ for its 
absent mate, and the keen distress of a hen on losing her 
chickens, furnish abundant evidence of vivid feelings of 
the kind in question. Even the stupid-looking ostrich 
has heart enough to die for love, as was the case with a 
male in the Rotund of the Jardin des Plantes in Paris, 
who, having lost his wife, pined rapidly away. It is remark- 
able that in some species — notably pigeons — conjugal 
fidelity should be so strongly marked ; for this shows, not 
only what may be called a refinement of sexual feeling, 
but also the presence of an abiding image in the mind’s 
eye of the lover. For instance, — 
Referring to the habits of the mandarin duck (a Chinese 
species) Mr. Bennett says that Mr. Beale’s aviary afforded a 
singular corroboration of the fidelity of the birds in question. 
Ol a pair in that gentleman’s possession, the drake being one 
night purloined by some thieves, the unfortunate duck displayed 
the strongest marks of despair at her bereavement, retiring into 
a corner, and altogether neglecting food and drink, as well as 
the care of her person. In this condition she was courted by a 
drake who had lost his mate, but who met with no encourage- 
ment from the widow. On the stolen drake being subsequently 
recovered and restored to the aviary, the most extravagant 
demonstrations of joy were displayed by the fond couple ; but 
this was not all, for, as if informed by his spouse of the gallant
