Well, another year, another failure.  just heard from the neighbour at the lake that the loons abandoned the nest yesterday.  It then rained like crazy and they can't even see the nest any more.  There is a slim chance they might start a 3rd nest, but it's very rare.  I think we're done again.  They made it to day 20; only 9 more to go and then failure.  So sad.  Might try blogging again next year!
