Plymouth, MA Patriot-Ledger: Until this year, the last report of a fully mature ivory gull in Massachusetts was in the 1800s.

PLYMOUTH â€" Jan 28th, 2009

The temperatures were in the single digits, but not low enough to keep the gawkers away. A celebrity was in town, behind the East Bay Grille, a visitor not seen in these parts in decades, if not longer.

But these weren’t paparazzi, and this wasn’t a Hollywood star. Rather, they were avid birdwatchers â€" about 20 in all â€" braving the frigid air as they scanned the bay and the edges of the breakwater with binoculars and spotting scopes.

And they would be rewarded, catching a glimpse of a glimpse of a rare, fully mature ivory gull. A birdwatcher reported seeing one in Plymouth last week, and another was spotted at Eastern Point Lighthouse in Gloucester. From Sunday through Tuesday, the avian visitor was a regular in Plymouth, much to the delight of birdwatchers, who came from near and far in hopes of adding the extremely rare bird to their life list.

Ivory gulls normally stay well above Newfoundland, living on Arctic ice where they follow whales and polar bears to feed on the scraps and carcasses they leave behind after making a kill.

Until this year, the last report of a fully mature ivory gull in Massachusetts was in the 1800s. Three immature birds were seen in the 1940s. In 1976, another immature bird had been spotted in Rockport.
