Drongo

An enterprising bird, the drongo forages individually
on the insects herded out by the movements of other
flocking birds. Insects compose 100 percent of a
drongo's diet. As one might expect, drongos that tend to associate with
larger flocks of other bird species (more than 20 birds) show increased
numbers of foraging trips and harvest a larger number of insects in a
given time than those associated with smaller flocks. The drongo and
the other bird species do not compete for the same food source, so the
relationship -- known as a commensal relationship -- is a good one for
the drongo. Drongos are considered remarkable for the courage with
which they will attack and dive off larger birds.

In Russian stories for kids, wolves were always pursuing Russian peasants
furiously driving horse drawn droshkys.

In Australian slang a 'drongo' is a stupid person or idiot. I wonder why? It doesn't sound like a daft bird.

Dear WW: everything is in metric now, and a good thing too. Grains, minims - too complicated

In using lead-tin solder in large quantities, as in repairing a large galvanized iron
pail, the molten solder oxidizes on to forming a film of dross that must be skimmed
off, as it can interfere with solder adhering to the work.
In working on printed circuit boards with a very small soldering iron and rosin core
solder, the iron tip has to be wiped immediately before being used for the same reason.
So the inert powdery oxides of the solder is called dross.
As a metaphor the term can be used to mean something worthless as dregs in something
of value.
