Jesse scopes for jaegers
The 2006 WSO Wisconsin Point Trip was the best one yet! I rode up with Jesse Peterson, Aaron Stutz and Tom Prestby on Thursday night. Given reports of jaegers earlier in the week, our expectations were high and we were generously rewarded for enduring some very rough weather. Though we saw many great birds over the weekend, my personal highlight was an incredible look at a lifer Pomarine Jaeger at about 30 yards away.
The weather on Friday and Saturday was exceptionally grim – 30 to 40MPH winds and pelting rain. This was sort of a mixed bag – on the one hand it meant great opportunities for bringing in jaegers and rare gulls, but there were several optics casualties. One barrel is completely internally fogged on my Swarovski 8x30 SLC’s and will have to be sent in for repair. A few scopes were unable to weather the storm as well, including a B&L Elite, Jesse's Zeiss zoom lens and an EO Raven.

My Swarovski scope got completely soaked, as did Tom's, but neither one of us had any problem with internal fogging. Pictured above, Tom and Aaron are looking at Tom's drenched scope. Below is a picture of Tom Schultz, WSO field trip leader, tending to his scope.

Luckily for me, Tom Prestbly's Dad arrived on the scene Saturday afternoon with a pair of EO Rangers he loaned me that dutifully held up in the rain. When the sun finally returned on Sunday, I switched to my Nikon Superior E's. Unfortunately, birds we were hoping to view in comparative comfort had apparently left with the change in weather – we went jaeger-less on Sunday.
Return of the Sun!
We had around 80 species for the trip, but I think the 5-day total for the "early birders" was something closer to 140. New birds for the year for me were:
Surf Scoter – WI YEAR
Sharp-tailed Grouse - LIFE
Sanderling – WI YEAR
Parasitic Jaeger – WI YEAR
Long-tailed Jaeger - LIFE
Pomarine Jaeger - LIFE
Little Gull – WI LIFE
Sabine's Gull – WI YEAR
Common Tern – WI YEAR
American Pipit – WI YEAR
Harris's Sparrow – WI YEAR
Red Crossbill – WI YEAR
I wasn't able to get on the Long-tailed Jaeger fast enough to identify it by plumage characteristics, but it's flight behavior and Jesse’s field mark descriptions (he saw it when it was much closer) were enough for me to add it, but hopefully I'll manage a better look next year. Nevertheless, it sure helped to read Olsen and Larsson's skua and jaeger guide before this trip. There were only a few jaegers that were either in poor light or too far away for us to identify, which is a good reminder that not all of them can be.
I was pretty thrilled to confidently distinguish differences between a juvenile dark morph Pomarine Jaeger and a juvenile dark morph Parasitic Jaeger that flew past us at close range within a few minutes apart – a nice visual comparison of flight behavior and plumage characteristics. In one excellent demonstration of jaeger behavior, I watched an adult light morph Parasitic Jaeger harass a Ring-billed Gull until it either dropped or regurgitated food – the jaeger caught it midair and made off with its pirated meal. Three gulls then chased the successful jaeger as it made a beeline back out to open water.
Getting a little waterlogged and worn from the adverse weather, on Saturday afternoon we scoped for ducks at Allouez Bay from the comfort of the pinewoods which blocked the wind. Within a few minutes Aaron found an adult light morph Parasitic Jaeger floating on the water! We radioed it in and many other birders joined us. The jaeger zoomed around the bay a few times but would return to the water – sometimes preening other times just resting. After harassing a few Ring-billed Gulls and coming up with nothing, the jaeger gave an excellent fly-over look as it headed out to Lake Superior.
Sunday morning we walked out to the Wisconsin Point Lighthouse and stayed long enough to find a pair of adult winter plumaged Little Gulls. We wanted to make a few stops on the way home for other northwoods specialties (Red Crossbills, Sharp-tailed Grouse, etc.), so we left the Point mid-morning.
