[Tweeters] Parasitic Jaeger Count off Point no Point

Just to express some agreement with Brad Waggoner's point, the highest
one-day count of Parasitic Jaegers in the Vancouver, BC area is ten birds. A
total of 40 birds would certainly be possible (and has undoubtedly been
exceeded) on a pelagic trip off the outer coast (e.g. off Westport), but
numbers seen in inland waters are almost always fewer than 10 in a day.

Subject: [Tweeters] Parasitic Jaeger Count off of Point no Point

Hi Roger and all,

Since a good deal of thes jaegers were distant, I would beg to ask why some
of them were not actually Heermann's Gulls? They do a great imitation of
immature jaegers when they too attempt to steal baitfish from other gulls. I
have numerous times tried to make them into jaegers. Now, If the 40 count
came back as something like at least 75% adult Parasitic Jaegers, then it
would be very difficult to argue with such an amazing count. I would also
wonder if they were seen swirling around all at one time and that the 40
count was reached at one point in time of viewing. They do pick-up and move
around quite a bit, so one really can't just keep adding as though there are
new bird showing. Note that the previous high count for inland marine waters
in Fall is 22. I can also say that count was probably Vic Nelson's at Point
no Point. And that it was his highest count in well over the 20 plus years
that he monitored and counted seabirds from his house just down from the
lighthouse. I should note also that Wednesday's counters only came up with
about 4 jaegers, with only one being an adult. The gull flocks were all
distant on that day too. I guess I am having a hard time with such a massive
presence of Parasitic Jaegers, especially given the low numbers of bonies
reported mid-week last week. Bonies become the favorite target of jaegers
once Common Terns have scooted on through.

Cheers and good birding,
