Ring-billed Gull Larus delawarensis

Rare transatlantic visitor. 28 records (29 birds) up to 2010.


 

There are 28 published records  of Ring-billed Gull (involving 29 birds) in the region up to 2010. Of the 28 reports, 15 were from Worcestershire (two of which visited two different localities), eight from Staffordshire, three from Warwickshire and two from the West Midlands County. Thus, Worcestershire has been by far the most productive county, with a series of early spring records suggesting a regular movement of one or two individuals through the county, presumably involving birds which are now permanently resident on this side of the Atlantic. There were five in Worcestershire during 2002, with four during late March and April. Of the 29 birds involved in the 28 records in the region as a whole, 17 involved adults, six second-years and six first years. The monthly distribution was as follows:

Thus, although a statistically small sample, the distribution suggests that records involve a combination of purposeful spring passage  and more random winter arrivals.
