This may be one of the better nests going forward this year. It looks to be more open, less branches, than a few of the others. At some point many of the nests will be covered by leaves and other foliage.
I had a nice open view of this male coming back after hunting around for food.
Of all the places around where we shoot, for a few months each year this view cannot be beat.
With a female he will build this out a little better. Not much though, master builders they are not.
If he can keep this nest until a female moves in this should be pretty safe for chicks.
