In a company of widgeons,
huddled under a cloud of bats,
a parliament of owls and
a wisdom of wombats
remark upon a loveliness of ladybirds.
A convocation of eagles
approach a tower of giraffes
who are watching a memory of elephants
applaud a cast of falcons.
In the distance, a flutter of butterflies
and a charm of finches
ignore a scold of jays
preferring instead
a flamboyance of flamingos.
Spurred into action by a doading of sheldrake,
a posse of turkeys, gabbling loudly to encourage a mutation of thrush, are startled senseless by a smack of jellyfish.

Nice, great use of the collective names. Although I now need to look up and see what a widgeon is!
Thanks for the compliment!
