I watched 2 adult Red-throated Loons from the viewing platform at  
Lafayette Square (31st Street, Park Point, Duluth) for about a half an  
hour this morning. The birds were initially less than 100 yards  
offshore and slowly drifted SE while diving and feeding. This  
represents the latest July date for this species in Minnesota. Spring  
migration of the Red-throated Loon normally extends into mid-June, and  
there are a number of late June and early July dates (see below).  
These two birds may be summering on Lake Superior instead of breeding  
farther north. It should be noted that Lafayette Square and other  
public access points along Park Point have been checked every day this  
summer, and that this is my only observation of this species since 22  
June (2 adults at the 12th Street access) and 26 June (2 adults  
between the Beach House and Sky Harbor Airport).

Except for a remarkable record from Murray County, 7 June 2003, and an  
undocumented record from Rainy Lake, 22 June 1963, all summer season  
reports are from Lake Superior, primarily at Duluth. Here is a list of
