OH poo
I completely forgot about this SGB
The nest here likely failed because of interactions between peregrines and great horned owls. During daylight hours, the falcons regularly incubated, but at night, they left their nest and their eggs untended when the owls (with young in their own nearby nest) were present and active. During hours of daylight, the falcons ruled the roost here, but at night, the owls were in charge. If the falcons continued to incubate at night, they would have been vulnerable to an attack inside their nest box by an adult owl. In such an attack, the owl would have been the victor.
As of this week, the adults continue to attempt to incubate their remaining two eggs (one egg was broken and removed by the adults), but at this point they won't hatch. As far as a re-nest goes, this only will happen when eggs are lost early in the nesting season. Since the eggs haven't been lost and
are still present, the falcons won't lay again. Eventually, the falcons will give up.
To alleviate this problem next year, a nest box has been installed on the new chimney south of the plant. Once I install the astro-turf deck later in the summer, I'll try closing off the old nest boxes (the owl box as well as the falcon box) so that only the new box on the chimney remains open. The falcons likely will locate the new box this fall and use it next spring - that is of course if the owls don't find it first! If this happens, I'll open up one of the old boxes for the peregrines and hope the distance and change in elevation between the new chimney site and the old nest site are sufficient enough to discourage the problems we experienced this year.
SO if he did get the new box up the Owls may be nesting there and there isn't a cameraMaybe you could contact greg and see whats happening
