Bob Dunlap just called to report that the jaeger in question is still 
present at Eagle Lake in Blue Earth County. He has confirmed most of 
the field marks mentioned in last night's posting and today, he 
observed a "double underwing flash" and determined that the bird's 
central pair of rectrices are rounded. The bird has been seen resting 
on the water and chasing Ring-billed Gulls--the jaeger has now been 
compared to multiple Ring-billeds and Bob stated that the its size and 
wingspan are similar to an average-sized Ring-billed's (i.e., some of 
the Ring-billeds appear to be slightly smaller and some of them appear 
to be slightly larger).

If documented and accepted by MOURC as a Pomarine Jaeger, this would 
represent only the third "inland" Minnesota record of this Casual 
species. All other records are from Lake Superior in St. Louis County. 
The two previous inland records are as follows:
8 to 24 November 1996 at Lake Pepin, Wabasha and Goodhue counties (Loon 
69:3-6);
22 November 1999 at Mille Lacs Lake, Mille Lacs County (Loon 72:56-58).

Probable Pomarine Jaeger, Blue Earth County

</bold>

This afternoon around 1:45 I found what I believe to be a juvenile
light-morph Pomarine Jaeger at Eagle Lake in Blue Earth County. This
is just east of Mankato on Hwy. 14. On the north side of Hwy. 14,
there is a small dirt pulloff from the highway from which you can view
the south part of the lake. It is here where I found the jaeger
sitting on the water. I watched the bird for over three hours and
called several birders, but unfortunately no one has posted anything
about it until now. Eventually Brian Smith, Jim Otto, and John and
Chris Hockema arrived and viewed the bird with me. The bird spent most
of the first two hours sitting on the water about 300 - 400 yards out
from where we stood, but during the last hour that I was there it
became much more active and flew around, chasing gulls, and coming a
bit closer to us.


Field marks:


-sitting on the water, head and neck light brown, contrasting with
darker brown wings and mantle that appear uniform in color


-in flight and when resting on water, identical to Ring-billed Gulls
in size


-in flight, obvious white uppertail coverts (rump)


-underwing pale and barred white, contrasting with darker upperwing


-white crescent flash in primaries of both upperwing and underwing,
but upperwing's flash fainter


-pale underparts do not strongly contrast with white primary flash on
underwing


-strong wingbeats, direct flight path


-heavy body, somewhat chunky-looking


-broad wings


-light gray bill with black tip


There will be others looking for this bird tomorrow as well. At this
point I am going to say probable Pomarine, as I am still awaiting
expert opinion, and then I will submit documentation to MOURC.


Bob Dunlap, Nicollet County
