Dear All,
One aspect I've never understood about this whole "birds introducing species
across the world" angle (BTW whenever this crops up I'm always reminded of
the Monty Python film "The Holy Grail" and the coconut -carrying swallow!!!!)
is the ability of small birds to carry an aquatic species, even a short
distance without it drying out.
Its hard enough to keep some of these aquatic species going (even U. Gibba)
in a "perfect" environment, never mind drying them out and transplanting a
number of hours later.
So what are the birds doing right that I'm doing wrong???? and specifically
how do they carry these pieces of plant material (bearing in mind that most
birds groom themselves on a fairly regular basis).
