Wagtail on the roof

A baby watched a ford, whereto
A wagtail came for drinking;
A blaring bull went wading through,
The wagtail showed no shrinking.

A stallion splashed his way across,
The birdie nearly sinking;
He gave his plumes a twitch and toss,
And held his own unblinking.

Next saw the baby round the spot
A mongrel slowly slinking;
The wagtail gazed, but faltered not
In dip and sip and prinking.

A perfect gentleman then neared;
The wagtail, in a winking,
With terror rose and disappeared;
The baby fell a-thinking.

A bit of colour and cheer on a rotten grey day - so glad the Grey Wagtail is more colourful than his name!
