Sigh of Relief

I think it's safe to say now that the two hatchlings of 2016 are flying that we survived the summer of 2016!
As far as we can tell, the parents were vigilant this summer, never leaving the nest and the babies unsupervised until they could fly; the eagle invaded our airspace -- barely -- several times only to be driven off by the parents.
This could be evidence that birds learn; that this is the pair who nested her last year and that they remembered the massacre and adjusted their own behaviour accordingly the following season.
Learning from the past -- if birds can do it, why can't humans? Ah, but as harsh as it is, this is the reason why we prefer nature.
