Red Shouldered Hawks nesting at Eaglecrest

Here's some info about the RSH from Cornell that I thought was interesting.

Cool Facts

Although the American Crow often mobs the Red-shouldered Hawk, sometimes the relationship is not so one-sided. They may chase each other and try to steal food from each other. They may also both attack a Great Horned Owl and join forces to chase the owl out of the hawk's territory.

The Great Horned Owl often takes nestling Red-shouldered Hawks, but the hawk occasionally turns the tables. While a Red-shouldered Hawk was observed chasing a Great Horned Owl, its mate took a young owl out of its nest and ate it.

Red-shouldered Hawks return to the same nesting territory year after year. One Red-shouldered Hawk occupied a territory in southern California for 16 consecutive years.

By the time they are five days old, nestling Red-shouldered Hawks can shoot their feces over the edge of their nest. Bird poop on the ground is a sign of an active nest.

The Red-shouldered Hawk is divided into five subspecies. The four eastern forms contact each other, but the West Coast form is separated from the eastern forms by 1600 km (1000 mi). The northern form is the largest. The form in very southern Florida is the palest, having a gray head and very faint barring on the chest.

The oldest-known Red-shouldered hawk was at least 22 years, 5 months old. It was banded in Florida in 1989, and found dead in Florida in 2009, the victim of an attack by another raptor.

Nesting
Nest Description

Both male and female build the nest, or refurbish a prior year’s nest. Stick nests are about 2 feet in diameter and lined with bark, moss, lichens, and conifer sprigs. The parents continue to add fresh green leaves throughout the nesting season.
Nest Placement

Tree

Red-shouldered Hawks often reuse nests from past years. Scientists don’t know which sex originally selects the nest site, although the male typically arrives back at the nest site first and defends the territory until the female arrives. They typically place their nests in a broad-leaved tree (occasionally in a conifer), below the forest canopy but toward the tree top, usually in the crotch of the main trunk. Nest trees are often near a pond, stream, or swamp, and can be in suburban neighborhoods or parks.


Makes me question where or not the South Nest is and has always been the RSH's nest. They don't steal nest so???? R4 brought up the question of why there has not been any nestoration activity in the South Nest by the RSH if that is where they are thinking about nesting again this season. This is going to be interesting to watch and see what happens.
I got a pic of both male and female this morning checking out the nest.

Today the RSH pair came to South nest. Keeping an eye out for the red-tailed hawks, they brought nest material in.

Good thing they are keeping an eye out. Today there was a brush off by an RT who didn't like the attention the RSH was giving the South nest. However, the pair of RSH were later seen doing some nestorations together until a shadow passed in front of the camera, prompting a hasty exit out the back side of the nest.
