First Egg Laid March 24 at 7:12 in the evening
Rosie laid her first egg, without fanfare, on March 24 at 7:12 in the evening. (19:12). This was earlier than usual and took viewers by surprise. But her return was earlier this year as well, so possibly it is just an early season.
Richie immediately took on dad duties and asked for his turn at incubation.

Richie has brought a female friend to visit, but Rosie will have nothing of it! Or was Richie trying to chase the female away? Who can know?

Bird Decoration March 26 cap by Diann a
Another osprey predilection that the humans don't understand: bringing desiccated bird carcasses to adorn the nest. Perhaps because there are no human made plush toys available this year? Insulation? Soft pillows? we humans can only groan and guess.

Egg #3 arrived March 30 at 7:29 pm. Chatters have become quite adept at identifying the signs of impending egg lay and many were watching the entire sequence. Rosie cooperated by putting herself in a position where the viewers could see well. The interval between this third egg and the second was 73 hours and 29 minutes.

Now begins incubation. Both Rosie and Richie incubate. In fact, Richie is noted for demanding his time on the eggs. This year, Rosie seems to be ceding him more time and he appears more relaxed in his duties. In his fifth season on this nest, he is an experienced Dad. (There is evidence that he was at the RTYC nest a year prior to this nest, so we don't know his entire mating/nesting history).
Richie's other duties are to guard the nest, flying to the nest anytime he sees an intruder, to bring fish to Rosie, and to bring nest items Rosie will also bring items. Unfortunately, both have begun bringing HMO's (human made objects) to the nest lately: two plastic bags, a hard red plastic thing and a rope. More information on these objects can be found in the Fish Matrix, logged along with the fish.

Life continues calmly for the osprey couple. Richie brings a fish or two daily. Otherwise, he stays nearby, ready to defend the nest when necessary. He is often on the rail, especially at night. And Rosie stays on the nest, except for short breaks. Richie will nudge her off the eggs and take his turn, while she bathes, catches her own fish or takes a poo break. It is fun to watch one tap its mate lightly with curled talon to urge it to get up off the eggs.
They have the routine down this year. There are fewer human made objects in the nest this year probably due to clean-up efforts by concerned citizens. There has been a brown plastic bag, which isn't too hazardous for the adult ospreys and two small red plastic items. Of course, Richie always has to have something red in the nest!

Good Samaritans cleaned up the Sandpiper Spit area and found the following. Midi and others also found fishing line at Tepco beach. Please, if you are are fisherman's dispose properly of your fishing line and lures. They are very dangerous to birds and other wildlife. A dead osprey was found recently at Pt. Pinole dangling from fishing line and hook. Also dispose of other trash in receptacles. Six pack plastic is very dangerous and are plastic bags and other human trash. Carelessness can lead to death for our beloved wildlife! If you see trash that is dangerous, please pick it up safely (gloves) and dispose of it in a receptacle.

On a happier note, eggs will hatch soon! See below for craigor's handy chart of potential hatch dates.
