Other Activity: First time I have been able to confirm female is present. This years nest is very different from all previous versions -much taller and deep in center so female’s head barely shows above nest. Scope needed to confirm presence. Based on previous visits with only binocs which suggested something in nest and the time the new nest took to build they have clearly been present since earlier in April.
