Rivet's return after (presumed) migration May 16, 2019 gif by Robin
I was thinking one day of the daily life of an osprey and how the daily pattern changed throughout the year. I thought how different this was from human's daily patterns, then I had an insight. The patterns are the same, based on the biology of reproducing and raising progeny. The difference is in the timing. While humans take many years to raise a family, the osprey pattern is compressed into a year. What humans do once, ospreys do every year for up to 20 years.
Rosie and Richie's year starts with Rosie's return to the nest. They get to know each other again, copulate (CK or cloacal kiss is used by chatters as shorthand). Richie re-establishes the connection by bringing Rosie fish and other presents. They both bring sticks, grass and other items to prepare the nest for the chicks. After a few weeks of this, Rosie lays the eggs, usually three. This happens in the space of a week, each egg one to two days after the previous. Now Rosie spends more time on the nest, incubating. Richie does some incubating too and also continues to bring fish. Rosie takes some breaks to fly off for a poop or even to catch her own fish. After 34+ days, the chicks hatch. Rosie is more restless during this period, although she stays on the nest. This is much like the newly wed humans, at first into themselves as a couple then focussed on the coming baby, setting up the nursery. 
Once the chicks hatch, Rosie stays on the nest to brood and to feed them. Richie ups his game bringing fish. It is mostly Rosie who feeds but Richie does some. He does not brood much. The chicks sleep, eat and poop. As does the human baby, while the mother nurses it and the father tries to help, sometimes needing a helpful nudge from the mother. What is it she really wants?
The chicks grow quickly and the parents build up the nest to keep their offspring safe. They also warn off all intruders. Put up baby gates and lock the door? Screen visitors? Sometimes the chicks/children squabble, establishing a pecking order, but as they mature, this fighting stops. All too soon, the offspring are ready to try their wings, the human children figuratively, the birds in reality. They make some attempts then one day they fly but many return to the nest for meals, after spending the day with friends. Remember Brisa and Rivet screaming, "I'm home! Where's my fish?" Or a teenager slamming the door, "I'm home, what's for supper?"
Then they truly fledge, fly off to establish their own lives. They live a few years independently,  associating with other young ones like themselves, learning to be an adult. They may stop by home, asking to stay for a while, but their parents tell them they have left the nest. And one day, they find a mate, build a nest, and the cycle starts all over again. 
Sound familiar?
Now, imagine raising a family once a year instead of once in a lifetime!

The chatters and lurkers of the Whirley Crane have witnessed this cycle three times now and are on their fourth year of watching. Each year, there have been more watchers and more documentation. I have tried in my posts to summarize these in text and caps both as memory for the long timers and as an overview for newcomers. Please let me know how this can be improved to meet your needs. And thanks to all who let me use their wonderful caps and gifs. Thanks to craigor and Robin who do so much for the cam. And of course, thanks to the GGAS and all the essential people-Cindy, Tony\, Moderator John who make all this possible!

​Egg Laying and Chicks

​2017                                                                    2018
eggs laid: 4/1/17
                 4/4/17
                 4/7/17 (overnight during a storm)
   
​The eggs hatch in order of laying.        
 hatched:             May 12 Whirley (WB)
                            May 14 Rivet     (ZR)
​                          
The third egg didn't hatch and was disposed of on 5/1/17 by Rosie 
Rivet and Whirley both fledged. Whirley flew off early in the morning on July 4, was heard that day then was fished out of the Bay by Dutra Dredging on July 5 and taken to Wildcare with a blunt force injury to her neck. (S)he did not survive. Rivet fledged on July 5, hung around the area then presumably migrated around August 20. Rivet made a brief return to the nest on May 16, 2019, was chased off by Rosie and is presumably still in this area. See below for possible range of area. Rivet is the first osprey to be banded, survive and return to Richmond.

Information provided by Tony Brake, our resident osprey expert and "caretaker" of the East Bay osprey nests.

Whirley died after an early fledging in the early morning. She was found and fished out of the Bay by Dutra Dredging and taken to Wildcare but could not be saved.

Peace-up (WP) was found after falling from a tree in Corte Madera on Oct. 1, 2019. He was buried onsite on private land. Authorities could not examine the body to find the cause of death.  

Rivet and Victory have been seen in the area.

​Fledging and Migration

Rivet is the first banded chick to fledge, migrate and return. According to Tony, he is a male and this is his likely area of settlement. Be on the watch for an osprey with a blue legband ZR! Victory of 2018 has also returned and was seen at Pt. San Pablo. Watch for the blue legend VU.

In 2017, Golden Gate Audubon set up live stream cameras to watch ospreys Rosie and Richmond, who nest on a Whirley crane in Pt Richmond, CA. Below are videos related to the nest, and other links that you may find
helpful. Post suggestions for other information to be included on the Live Chat at www.sfbayospreys.org.
