The highlight of the day was a pair of nesting Gray Hawks that were forced to protect their nest from a marauding Raven while we looked on. The Raven is the larger of the two birds and it kept flying close to the nest which had young calling out in it.
The nest was placed perfectly in the tree so that it was impossible to get any more than a glimpse of it from the ground and we never saw the young birds at all.
