    Although Iris would not take this gift of food directly from Rusty, she is happy to retrieve it later when he is not around.

    See, This Is What You Do

    Rusty seems to be showing Iris how to incubate. Just after we captured this moment, they switched positions. Iris has shown a lot of interest in the nest since yesterday evening.

    Iris' Egg

    Iris rarely gives us a glimpse of the egg that she has been diligently incubating since the 21st of January. Eggs are incubated for 28-35 days.

    We finally get a glimpse of Iris' two white eggs! If all goes to plan, they should hatch around Feb. 22-24.

    What Large Wings You Have

    Feb 01, 2012 -
    Rusty's long wings are seen fully stretched out here. A male's wing can be over 14" long. Imagine being a small mammal in this big guy's territory!

    Rusty Means Business

    Feb 07, 2012 -
    Rusty stands guard on the platform. Still on squirrel patrol, he's determined not to let any more intruders disturb the peace. The squirrel eventually found its way out, unharmed by Rusty.

Jan 18, 2012 - Rusty & Iris Hooting at Nest
Here we see Iris hooting with Rusty while on the nest. She has been spending a lot of time on the nest lately. It looks promising that there could be a nesting attempt soon (if not already).

Rusty gives his territorial hoots into the camera while Iris incubates and calls back to him. One to five eggs are typical for the species; she has at least one egg now.

Feb 01, 2012 - Incubation: Day 12
Iris returns after a short break, taking care to position herself ever so cautiously on the eggs. Rusty hoots unseen from the platform, while American Crows and a third Great Horned Owl call in the distance.

Iris placidly looks on while an infuriated Rusty chases away this trespassing squirrel who has found its way into the flight cage. (Speakers recommended)
