I didn't recall mention of gulls or terns in the original report at Timothy
Lake, which
is why I didn't expect the jæger to hang around. I saw a Parasitic Jæger at
Orchard
Point, Fern Ridge Reservoir, in Sept of 1993 I think. It was with a sizeable
flock of
Common Terns, which were still around the next day. A significant frontal
system
was passing through when we saw the Parasitic, which provided good sailing for
the stout of heart. After the winds died down, we came across a Long-tailedsleeping on the middle of the lake, which allowed for better views than I've
Jæger
Lars, Peter et al.,
Inland jaegers are often found in the company of small gull and tern species
that they harass in order to get them to drop food items. There seems to be a
strong correlation between the timing (late August thru much of September) of
inland migrant Common Terns and Sabine's Gulls and inland Parasitic and
Long-tailed Jaegers. When Common Terns and Sabine's gulls show up at large
inland lakes and reservoirs (i.e. Timothy Lake or Fern Ridge Res. near
Eugene) they often hang around for several days. I suspect that Jaegers do
the same. Being that jaegers spend much of their life at sea out of sight of
land, I think they are inclined to stay far from shore at inland locales as
well. When I lived in Illinois, the local birders ran "pelagic" trips on Lake
Carlyle in south central Illinois. Nearly every year they would find
Parasitic Jaegers and occasionally Long-taileds, but always way out in the
middle of the lake far from shore. It was quite rare that anyone ever saw a
jaeger from shore at Lake Carlyle. Sabine's gulls are similar in this
respect. When I have seen them sitting on the water at Fern Ridge, it was
essentially out in the middle of the reservoir as far from land as possible.
When not up flying around chasing gulls and terns, jaegers can be virtually
impossible to detect as they sit on the water. When sitting on the water they
maintain a very low profile and being mostly dark, they blend into the water
surface, especially if the water surface is not calm and glassy. A sitting
jaeger could easily evaporate out into the middle of Timothy Lake and go
unnoticed for many hours.
Timothy Lake is certainly worth checking anytime from now until early
November. Late August through much of September is the best time to find the
species mentioned above, along with Eared Grebes, Red-necked Grebes, and
various other waterfowl. Moving into October and into early November is the
best time to find inland scoters, plus various other diving ducks. It is the
best time of year to find inland Pacific and Red-throated Loons as well,
along with large rafts of migrating Western Grebes that may include the
occasional Clark's Grebe.

Long=tailed and Parasitic Jægers routinely appear in western
Oregon inland locations in September. They are very much on
the move. I wonder if any stick around for an hour, let alone
overnight. The frontal system arriving Sunday night could bring
more to unexpected spots, along with Common Terns, Sabine's
Gulls, a few other species more often seen on pelagic trips. Lars

Has anyone been out to Timothy Lake to see if the jaeger reported earlier
this week is around? Considering going there this weekend. Would appreciate
positive or negative reports. Thanks.
