Bald Eagle pair at Delta Ponds. This is likely the pair that nests on Skinner Butte. The nest, on top of a tree, is huge! Here is a video about the nest there - https://www.youtube.com/watch?v=3nq061p10rU Check it out, worth watching!

Below is some information about eagle life history and reproduction:

"Bald eagles are solitary, but monogamous animals. Although they spend winters and migrations alone, bald eagles maintain the same breeding pair year after year. A mated eagle pair finds a nesting site and produces offspring each year. If one of the pair dies, the surviving bald eagle will look for a new mate in the next breeding season. The nests are built on the tops of trees. The pair uses sticks and twigs to construct a platform nest. Some pairs return to the same nest the following year. Bald eagles normally lay two or three eggs. The eggs are incubated for about 35 days. Depending on the location, the eggs are laid in the winter or spring." - (Quoted from National Wildlife Federation website - https://www.nwf.org/wildlife/wildlife-library/birds/bald-eagle.aspx)
