This morning I spent some time photographing a Anna’s Hummingbird ( Calypte anna ). I watched it perform this elaborate swooping or diving aerial display. The male hummingbirds usually do these displays for females. The Anna’s Hummingbird does a steep, J-shaped dive, curling around at the bottom. It also produces a distinctive sound at the bottom of the dive, which I heard. Very cool.

The Bald Eagle ( Haliaeetus leucocephalus ) builds one of the largest nests of any bird. It can be 1.3 to 3 metres wide. Sticks are weaved together and they fill in the cracks with softer material like grass and moss. Both the male and the female bring materials to the nest, but the female does most of the placement. A nest can take up to 3 months to build and may be reused year after year. After laying the eggs the incubation period is 34 to 36 days. Both the male and the female take turns sitting on the eggs, but this is mostly done by the female. During this time, the other Bald Eagle is hunting for food or is perched close by to guard the nest, like in the photo. When I took this image it was windy and challenging for the Bald Eagle perched on the branch to maintain its balance.
