9:20 AM to 9:35 AM
at: Saugus
Number of Adults Visible: 1
Number of Nestlings Visible: 0
Number of Fledglings Visible: 0
Weather Conditions: 75, partly to mostly cloudy, humid, almost no breeze
Other Activity: One adult on nest, after 10 min it flew low around and came back. Couldn't tell--too--far if it had a fish in its talons. Might have been feeding chicks I couldn't see, or not, really too far to tell. They built a high nest. Seen them do this many times so don't know if they are successfully fishing and feeding chicks or not. They started nest a couple weeks or so later than SAU-03.
Observation Method: foot
General Comments: When they are flying model airplanes, which at this time of year they always are when I'm there, I have to stay decidedly further from the edge of the marsh so have more trouble seeing what is actually happening. Just a fact, I don't have a spotting scope!

Weather Conditions: 75, partly to mostly cloudy, humid, almost no breeze
Other Activity: Saw 4 ospreys on nest. Light such that could only see in silhouette so couldn't tell young from adults, and they all looked about same size. One appeared to feed one chick, and before I left one flew off. There had been 3 chicks though I only saw 2 last time, so possibly 3 chicks and one adult? One guy in model airfield said he'd seen some wing-flapping during the week, but I didn't see any today.
