I have a large birdbath in the traditional saucer shape. It is
very popular with the wattle birds and blackbirds. Also currawongs and
rosellas. Haven’t noticed ravens in there a lot, but sometimes.
When it gets grungy, I simply tip about half a cup to a cup
of bleach in, stir and top up.
If you think about it, the concentration is low almost from
the start and since it is busy chewing up the greeblies, it is not really a
toxic mix at any point. I usually keep an eye on it for a little while to make
sure nothing uses it . After that, it smells about the same as the average swimming
pool for a short while. I would guess it probably tastes about like the tap
water on a day when they have been putting extra chlorination in (after all, bleach
is just sodium hypochlorite).
It does not seem to deter any of the regulars and I doubt it
does them the slightest harm. Indeed, if they bathe in it when it is dilute
they are more likely to gain parasite reduction than suffer plumage fade. Much the
same as persuading poor kids to use the swimming pool regularly to combat
scabies, etc .... J
