Is there an annual climber that I can plant that is beneficial to
bees/birds/butterflies?

I've got some nice things that I planted last year but I have a VAST fence
to cover and I'd like something quick for the summer - I've got some morning
glory seeds, any good? I can't be arsed with sweetpeas because of all the
hassle of picking them, and they won't be in a very accesible place (back of
border).
