very sad today..... something has happened to the chicks

So sad to report that yesterday morning there was only one chick left in the nest. Both parents were very attentive..... and then this morning, one of the local photographers who had been watching the nest twice a day, discovered that the second chick was not there early this morning.  They are far to young to have flown away. Either a predator attacked the nest at night, which seem unlikely as the female would not leave the nest; or the nest was not sturdy enough and they fell out..... I guess we will never know.

This was the last photo I got of the remaining chick last evening...
