Hi - I cannot confirm or refute your id of this bird, but I have a fair amount of experience with Brown Booby and several other sulids, and can say a few things about how they look in flight. First, they fly faster than a lot of seabirds, probably noticeably faster than a traveling (not chasing) jaeger. Second they look very distinctly pointed at both ends. The have longer necks than jaegers and shearwaters, heads that in flight do not look much bigger than their necks, and conical bills that tend to be pointed straight in front of them (except when foraqging). They do not look as long-necked as cormorants. They tend to look flat-bellied, or thin-bodied. Hope this helps.

Our first stop was at the North Jetty ~8:00AM. We had a clear window for awhile before the dense fog rolled in. We set up our scopes at the edge of the channel near the parking area for our first look. I scoped out beyond the jetties, and one of the first birds I got on was gliding south to north, low over the water beyond the mouth of the jetties. I first called out shearwater. Then it flapped and I saw a bright white belly contrasting sharply with a dark neck and head. It wasn't flying right for a shearwater and I thought the tail looked big, so I jumped to Pom Jaeger. That wasn't right either. It was flapping slower than a jaeger and there were no white flashes in the wings. My next thought was way out there, but I thought it was right for Brown Booby! That is what it really looked like. I watched it for 30 seconds or so, and could not give good enough directions for Barry to get on it before it disappeared behind the dunes. We ran further out on the jetty to try to catch it again, but it had vanished in the fog to the north. We drove up to Haceta Head and looked over the rocks at Sealion Cave and from the lighthouse, but the fog made visibility very limited. I really don't know what it was. I know Booby is a super long-shot and my description is lousy, but thought I'd better get this out there in case it's still hanging around somewhere. We did see a flock of ~ 14 ELEGANT TERNS feeding off the north jetty, moving north. Good Birding, John Sullivan Springfield, OR
