It has been a rather rocky ride and we hope the next month or two will be calmer, with the ospreys remaining healthy, plenty of fish caught, and successful migration later in the summer. As every year, the chatters and lurkers have learned much from the ospreys.
It is known that the bird is young due to the white marks on the feathers. It is assumed that she is a female due to certain behaviors, her heavier size and her speckled chest. It is also assumed that she fledged from a nearby nest recently and is now exploring.She still expects to have a fish brought to her but can eat one by herself.
Instead of rebuffing the visitor, Richie and Rosie upped their fish bringing. Below is the statement from the Fish Matrix Master at 5 pm. More fish came later.
"Four for Rosie today ties her season best. Highest total for a day this year is eight, six for Richmond and two for Rosie. Would not be terribly surprising to see that exact ratio reversed today. She just needs to bring two more by nightfall.
Six fish today and the last four have been eaten by some kid from down the block."
At 5pm, a smelt was delivered by Richie. At 5:46, a goldfish was delivered by Rosie. Trudy flew off. Brooks flew in to claim a fish and Trudy came back to reclaim the fish. They had a struggle over the goldfish. At 7pm, Brooks was on the nest again and Trudy landed on her, still clutching the goldfish. Brooks was mantling over the herring that had been brought earlier. Trudy attacked Brooks and Brooks went into a submissive position.
The morning of July 27, Rosie delivered a pfm to the nest. Trudy immediately came rushing in to claim it, screaming all the while. She then flew off again. Brooks has not been seen on the nest but may be nearby and may be fed off the nest by her parents.
Migration time is fast approaching. The human observers never know when this actually happens as the juveniles fly around, going farther and farther away from home, then one day in August they are gone. We do usually see Rosie and Richie together one last time before she migrates, usually in September. Keep your eyes peeled for blue bands around the East Bay!
Week 12: August 1-7 It's All About Fish
Chatters too have quieted down and are showing up less. They seem to have accepted the state of affairs, now that Brooks has been located. The osprey season is winding down.
Craigor, the Fish Matrix Master, made a wise statement recently:
Somebody has probably mentioned this, but all these intruders, plus our faux-Rosie and faux-Richie (remember?) visitors this year, and chicks swapping nests... is probably all a sign of a healthy and growing local community of O's. There's just more O's around than there were a few years ago so they run across each other more often and have to change their behavior accordingly.
And I even seem to recall reading that O's will act territorial and defensive up to a certain population density, but when they get really numerous (as on Cape Cod back east) they shift to more of a colony-type behavior with more comfortable and flexible sharing of territory. And I suspect we're seeing evidence of reaching that density.
I did note from Tony\'s remarks that it is now the Richmond shoreline and not Mare Island that is the epicenter of Bay Osprey life.
Just when life on the nest seemed to be calming down, Trudy surprised everyone by bringing a fish to the nest. And not just any fish, but a shark! And it appears she may have caught it herself. She brought it quietly, not screaming as she does when offered a fish by Rosie. She ate it to the last bite. It is thought that she caught it herself by Brooks Island. See video on Youtube.
Fish Matrix master craigor said: "Sensible. Just had to eat around the hook until it pulled loose, then there was nothing holding the line to the fish anymore. So, lift it off the nest, give it a good shake, presto!"
Birdbrain remarked: "It's funny how what we had deemed 'bad table manners' (spitting out the skin, leaving the spine hanging on a wire) turned out to be what saved the day."
Many chatters changed their opinion of Trudy that day, no longer a spoiled screecher but, as more than one said, a Warrior Princess.
In others news, word came back that both Brooks and Molate, who were given a DNA test while being banded, are male. Trudy did not receive a test so we can only go by appearance at this point. Most seem to think she is female.
