The purpose of this post is to present a precedence that I think is noteworthy. This is now the 4th time - at least - that out of range Ivory Gulls have appeared in duos.
- St. Paul, Minnesota. 15-23 December 1991. Both 1st cycles. Although initially only one was being seen, and only one was thought to be present, both birds were eventually observed together.
- Port Washington, Wisconsin. 31 December 1997 - 03 January 1998, 1st cycle. 10-13 January 1998, adult. Many birders came up the first week to see the 1st cycle, and drove right back the next week to observe the adult.
- Northumberland, UK. 07 December 2013. Two 1st cycles. Initial sighting was of one bird, and then while observing this bird a second individual appeared.
The three examples above weren't Ivory Gulls found a couple miles apart, they were found at the exact same site. For a gull that is supposed to be very rare away from the arctic, this pattern of duos at the same location is curious, to say the least. Does this occur more often than we know?
