New thread.

A young elementary school student that my wife teaches has set up a very cool blog called Save All Owls.  Check it out here and give her some love and support for her excellent work.



New thread.  Third egg!  Debi pic below.


First egg thread. 

From our biologist Dr. Jim Siegel:

The egg laid today is likely to hatch after about 35 days, aroundMarch 19.   One or 2 more eggs are likely to arrive over the next 4 to 5 days, with accordingly later hatching dates.  Although  the female will likely do most of the incubation, both sexes have developed a brood patch and will continuously incubate the eggs, turning them every so often for even warming and to maintain a healthy relationship between the embryonic membranes and shell. The eggs must remain covered to avoid cooling.


Here's a note I got from Dr. Jim Siegel on my staff about the nest visitor yesterday.  Jim has studiedsanderlings, scrub jays, great blue herons, brown creepers, hermit thrushes, and a few others pretty intimately,  including their territorial, reproductive and feeding behavior. Observing eagles is a hobby for him, so here are his thoughts:
"Birds are instinctual creatures.  If the male is bringing in fish without young in the nest (Feb 4) , he is provisioning the female - feeding her as if she cannot leave the eggs or young and making sure she is fit and healthy to reproduce.  The fish may have attracted the sub-adult (Feb 5) 
I am not convinced the sub-adult is a fledgling from 3 years ago just hanging out and visiting its parents.  Fledglings of long-lived predatory birds have to disperse widely from home or  they will be constantly competing with their parents who may live for decades in the same place.  Every young born cannot stay home and wait for their parents to die;…


Lot happening on this windy February day in the nest.  Check the webcam page for an update. 

We have not observed this before at this nest, and while things were civil today they could get rough for the juvenile soon enough.  Time will tell.

New thread.


We are watching the goings on at the nest.  If an egg was laid this AM, the fact that there has been no incubation for this many hours is not a good sign for this particular egg (if there is one).

We'll be preparing an update and will continue to watch.
