Eagles at Norfolk Botanical Garden 'As the Nest Turns' continues! According to Reese Lukei, 'This female with the black in her tail, known as #3, was last seen in the nest with the male on Jan. 30th. She was first in the NBG nest on Jan. 20th. Since Jan. 31st, another female, likely #2 (with the male Jan. 8th-19th), has been with the male and mating with him. #3 was seen Feb. 6th soaring above NBG. Yesterday, at 3:33pm she returned to the NBG current nest tree.' Here's the breakdown of the females you may have seen in the nest and the dates: Female #1 - Sept. 2011 - Jan. 6, 2012 Female #2 - Jan. 8 - 19, 2012 Female #3 - Jan. 20 - Jan. 30, 2012 Female #2 - Jan. 31 - Feb. 6, 2012 (Either #2 or a 4th female!) Female #3 -- Feb. 7 *Whew*  Dad better find 2 more nests!! Wonder whatever happened to #1? Doesn't sound like he's going to settle anytime soon! |

Audubon Starr Ranch Barn Owls
02/06/12 A note on the Male BNOW: In what I would describe as almost an impossibility or at least up against astronomical odds (and I think most biologists would agree) last Friday, 2/3/12, the male BNOW was found dead by Sandy’s field crew 0.6 miles north of the cavity in the corner of a grassland next to a small oak canyon. He was completely intact and appeared to have been dead for 2 or 3 days. Yet he’s been gone for approximately 2 weeks. What was he doing/what was happening to him during this time? A quick examine indicated no broken bones and no usual signs of starvation, such as diminished breast muscle causing a prominent keel. However, he is in the freezer and perhaps Dr. Scott Weldy from the OC Bird of Prey Ctr/Serrano Animal and Bird Hospital might be able to determine cause of death through some tests and necropsy. I believe it may be possible to test for anticoagulants that might have been picked up should the male have eaten a poisoned rodent (Note – no pesticides or herbicides are used anywhere on Starr Ranch but we are close by areas that do). It’s also possible that it might have been West Nile Virus, but I’ve been told that this is difficult to test for after the bird has been dead for as long as he was. Also, it just might have been old age. The Bird Banding Lab record for the oldest wild BNOW is 15 with 2nd and 3rd “place” belonging to BNOWs btw 12-13. This male was banded in 2006 at at least 3 yrs of age so he was 9 and could have easily been older. Bottom line is the male is confirmed dead and at this point from unknown cause(s)
A note on Fostering. The search continues for another cavity to foster some if not all of these chicks. Others and I have not given up, but this effort is very time consuming and often requires travel to remote areas that in some cases are now even less accessible because of road damage caused by flooding in Dec 2010. Nonetheless, we will press on. But I feel the need to raise something in hopes that it will better prepare you if we should be fortunate enough to find an appropriate foster nest. If we do the chances are greatest that the smallest chick(s) will be fostered. This means they will be removed from this cavity and you will not see them again. But more important it means they will have been given a much greater chance at survival than they have now. The supplemental feeding will continue, but as I’ve mentioned numerous times chicks require supplemental feeding by the adults for weeks after they fledge and it isn’t a given that continuing to put food in the cavity will get used at this point.
