I have pulled some background information on the Sauces nest from the annual reports. More information can be found at the links below. There is so much information being produced it is a credit to the small band of volunteers that collect, collate, report and post so much of it. The two links cited below are just a small sampling of the information available. Page 3 of the second link shows where you can find all the annual reports. The 2016 report has not been filed yet.

14th Annual Report
Page 10
Santa Cruz Island
We surveyed the 7 known breeding territories on Santa Cruz and located active nests in 5 territories (Sauces Canyon, Fraser Point, Cueva Valdez, Fry?s Harbor, Malva Real; Fig. 9). We surveyed much of the island for new territories in conjunction with peregrine falcon surveys and located 2 new breeding territories: Baby?s Harbor and Smuggler?s (Fig. 9).
Sauces Canyon Territory. The Sauces Canyon pair (Fig. 9) used the same nest as in 2014. Male A-40, a bird from the ACC, was hacked on Santa Cruz in 2005. The female, A-48, an ACC-produced bird, was hacked on Santa Cruz in 2006. An egg was laid on 7 February and we were not able to confirm whether more eggs were laid. The nest failed during incubation on 15 March and there were no further nesting attempts.
We replaced the camera with a different camera in November 2015 and raised it about 1.5m higher so that we should have a better view into the nest, as well as night vision, in 2016.

Sauces Canyon Territory. The Sauces Canyon pair (Fig. 7) used the same nest as in 2013. Male A-40, a bird from the ACC, was hacked on Santa Cruz in 2005. The female, A-48, an ACC-produced bird, was hacked on Santa Cruz in 2006. The first egg was laid on 15 February, but broke on 22 February. The first egg of a second clutch was laid on 16 March, but soon after the egg was laid A-40 returned with a large, forked stick that got caught around A-48?s neck, causing her to step on and break the egg. There were no further nesting attempts.

Sauces Canyon Territory. The Sauces Canyon pair (Fig. 9) used the same nest as in 2012. Male A-40, a bird from the ACC, was hacked on Santa Cruz in 2005. The female, A-27, was collected from Alaska and hacked on Santa Cruz in 2004. The first egg was laid on 24 February and a second was laid on 27 February. Normal incubation continued until 4 March, at which time A-27 stopped returning to the nest. A-40 incubated alone until he left the nest on 7 March, at which time ravens flew away with the two eggs (Fig. 10). On 12 March, the Fraser Point female, A-49, was seen visiting the nest, although she had eggs at her own nest by this date (see below). A-49 showed up on the nest until 15 March, at which time A-48, an ACC-produced bird released in 2006, was seen at the nest. A-48 was seen in the territory through the end of the year.

Sauces Territory. The Sauces pair used the same Sauces Canyon nest as in 2011 (Fig. 7). Male A-40, a bird from the ACC, was hacked on Santa Cruz in 2005. The female, A-27, was collected from Alaska and hacked on Santa Cruz in 2004. The first egg was laid on 2 March and a second was laid on 6 March. Chicks hatched on 8 and 10 April
We entered the nest on 8 June to install leg bands, VHF transmitters, and wing markers on the eaglets, and to obtain blood samples (Fig. 8, Table 2). Eagle A-81 fledged on 21 June and A-82 fledged on 2 July. A-81 was seen on Santa Rosa on 30 August, but he returned to Santa Cruz within about a week. On 12 September, we found him in a narrow erosion gully from which he could not escape on the west end of the island. We accessed the gully with a ladder, captured the bird, and placed him in a dog crate. Once the bird was out of the gully we provided him with fish (it is believed to have been trapped for a couple of days) and released him near Christy Ranch. He was seen flying and feeding several times after his release and was last seen on 22 September. He likely moved to Santa Rosa around this time, as we did pick up a signal from his transmitter towards Santa Rosa on 5 November. A-82 flew to Santa Rosa by 31 August and we last received a signal from her VHF transmitter on 9 September on Santa Rosa.
