According to what I have learned by following Hob Osterlund, bird protector on Kauai and author of 'Holy Moli`', albatross mate for life.  I'm not sure about whether they will find another mate if theirs dies, I've asked Hob to respond to this article.  I believe a mating couple have one egg per hatching season.  I do no know how long it take for an albatross to reach reproductive maturity, but the population is small if not endangered so any loss of reproductively mature birds is a huge loss to the population.  It is recoverable over time, but we cannot let this horrible incident happen again.
