A group of flamingos is called a “flamboyance."

 This day, whate’er the Fates decree,

Shall still be kept with joy by me:
This day then let us not be told,
That you are sick, and I grown old;
Nor think on our approaching ills,
And talk of spectacles and pills.
To-morrow will be time enough
To hear such mortifying stuff.
Yet, since from reason may be brought
A better and more pleasing thought,
Which can, in spite of all decays,
Support a few remaining days:
From not the gravest of divines
Accept for once some serious lines.
