Part 1: Waiting for Rosie
Feb. 17-23
The ospreys are returning. Chatters can see them flying around the nest. Richie is coming almost daily to the nest and has found some visitors. A female has come to the nest and there has been some mantling. We expect Rosie any day now. Feb. 23: the female has come the past three days. Richie attempted one CK.
Feb. 26
The young female has been coming regularly to the nest. Sometimes Richie joins her and mantles. sometimes she sits there alone. She seems more comfortable and calmer now. Everyone remarks on her beauty: prominent eyebrows and many speckles on her chest. Richie appears to be spending time at the RYC nest as well. Other signs of courtship are beginning, such as bringing nest material.
Meanwhile, everyone is watching for Rosie. For she is integral to the beginning of the season. Richie is always around, so we know what to expect from him. But Rosie is the big unknown, presumably staying in El Salvador or other Southern region, and returning each year around this time. Rosie, where are you? Richie is waiting, as are we all! In 2018, Rosie arrived on March 2 and in 2019 she arrived on Feb. 23, so we are still within that range.

Fish: See the Fish Matrix under the cam view: 4 fish have already been logged for this year, all brought to the crane but not the nest. Richie (or other osprey) has also been seen quite often on Marker 12 eating a fish. There is no need to bring the fish to the nest without a mate or chicks there.
A female nicknamed Delilah took up residence on the nest in late February. She was stunning, with dark eyebrows and a full speckled chest. She also appeared to be young and inexperienced. Richie mantled to her but didn't cater to her as much as he does to Rosie. He brought an occasional fish, one an oddly stiff one, and some nest material. Dlo, as she was then named, paid no attention to the nest material. She was apparently not ready for nesting. Later, there were some air battles with three or four ospreys involved. And when Rosie arrived March 5, there was a brief skirmish, then Rosie settled in and Dlo has not been seen.
