When writing about the frigatebird, two blogs ago, I neglected to comment on its most noticeable and outstanding physical feature: its gular pouch. It is an inflatable, red-coloured throat pouch used as part of the courtship display.
To make amends for the oversight mentioned above, I have written the following verse.
The frigatebird has a grand pouch
When displaying it he's no slouch
If this sac's bright red
It's time he was bred
If not, he turns into a grouch
Please comment if you wish.
