This morning as I arrived I found one adult (female) in a tree near the nest tree.  The male showed up and entered the nest for a few minutes.  His occasional vocalizations were answered (more softly) by the female.  The male then flew to the female's location and mated with her.  The female then flew off to a tree to the west, and the male followed.

The nest has failed this year.

Today I observed the hawks at their nest from about noon until about 5:30pm.  Most of that time was fairly uneventful, except when the bird in the nest left to perch briefly with its mate in a nearby tree.  The longest the nest was left unattended was 5 minutes --- at about 5:44pm the male left the nest flying directly in a southerly direction, to disappear out of sight, only to return 5 minutes later from the same direction.  In all cases the adult on the nest sits low as if incubating eggs, rising occasionally to reposition him/her-self and sometimes to (as I imagine) turn the eggs so as to achieve more even heating of the embryos within.  The adults did copulate on a nearby limb in the mid-afternoon.  When I left at about 6pm only one adult was in view, on the nest.

This weekend I spent at least 5 hours both days at Duke Gardens, but did not observe any red-shouldered hawk activity at or near the nest.  Rollen W. again proved to be a hawk-magnet by finding a juvenile Cooper's Hawk actively hunting at the feeder in the bamboo stand near the parking lot.

This morning I arrived at the Gardens and began photographing songbirds near the parking lot.  After encountering a singing Rufous-sided Towhee and an Eastern Bluebird I observed a red-shouldered hawk land in a tree.  Immediately thereafter another hawk perched beside the bird.  Soon the male mounted the female in copulation. This took place in a tree not far from a nest in which fellow photographer Rollen W. had observed some red-shouldered hawk activity only days prior to this.   

     


Update: Cynthia F. informs me that a pair of red-shouldered hawks bred in this location last year.





Note on equipment:  For photos taken prior to mid-March 2008 I used a Canon EOS 1D Mark III camera attached to a Sigma 800mm f/5.6 lens with a 1.4x or 2.0x teleconverter attached, for an effective focal length of 1120mm or 1600mm (not taking into account the 1.3x crop factor of the camera).  This combination does not allow autofocus, due to the use of the teleconverters, so the camera was focused manually using the "Live View" feature on the Mark III. A flash unit (Canon 580EX II) with fresnel extender (Walt Anderson's "Better Beamer") was used on some shots.  The entire rig was supported by an Induro carbon-fiber tripod and Manfrotto gimbal-type head.  All photos were shot in RAW format and processed in Photoshop Elements.  2009 Update: photos were taken with a Canon 1D Mark III attached to the Canon 600mm f/4 lens with 1.4x or 2x teleconverter, shot in RAW, and processed in Photoshop CS3.
