[Tweeters] Are our "early" Ospreys not "arriving", but only "passing through"?

Last year, the Magnuson Park Osprey was back near the platform on NOAA property on March 28. I haven’t seen either of that pair back yet this year. The nest on BNSF property near Fisherman’s terminal had an Osprey perched this morning.

The other was perched on a Cottonwood limb -- a Cottonwood in which I often see an Osprey perched from spring through summer. One of those nests now seems to be occupied by a Canada Goose. I presumed they all intended to spend the season here.

I led a Seattle Audubon trip along the lower Duwamish River today - no Ospreys spotted anywhere from Jack Block Park to Cecil Moses Park.

>> In the 1981-1984 period I participated in aerial surveys of bald eagle nests in western Washington and we would occasionally encounter an osprey perched on or very close to an existing osprey nest in the April 10-15 period. I always thought that these were birds that would eventually nest at those sites. To me, they seemed to be the earliest arrivals and active nesting was still weeks away.

>> If I'm not mistaken, years ago I estimated that the pair of Ospreys, that nested on the light post between the West Seattle Bridge and the Ash Grove Cement plant, arrived about April 23rd. That said, every year I read Tweeters reports I hear of Ospreys "arriving" weeks earlier in different spots in Washington. I haven't kept careful track of what day I see the first Osprey on that nest, but it is never weeks earlier than that April 23rd. My thought was that maybe those first reportedly "arriving" were really "passing through", and the first sighted migrants were headed to the most northerly nesting sites. Does anyone have information on whether the earliest Osprey sightings in Washington are not arriving at nesting sites, but that they may be only passing through to nesting sites the furthest north? These earliest Ospreys that may be only "passing through" have long been referred to as "early". If it turns out that all of the earliest sightings are just sightings of those headed the furthest north, maybe we would stop calling them "early", and maybe start calling them something like the "first passer-bys and most northerly destined".
