When a nest was disturbed one of the parents or both 
usually stayed about making a clicking noise. This habit was 
observed in other species as well. 
Young and immature birds were observed as follows: 
February 23; Wreck Bay, Chatham. Mr. Beck took one or two well- 
fledged young ones. 
March 8; Southeast Albemarle. One bird of the year was taken. 
March 13; ten miles west of Villamil, Albemarle. I took a young bird 
of the year. 
March 15; Cape Rose, Albemarle. I saw two or three immature birds. 
One was being fed by an adult male. They kept up a continual 
chirping. 
March 19, 20; Iguana Cove, Albemarle. I saw several young birds and 
noted a black male feed two well-feathered youngsters. I found a 
nest on the 19th containing four unfledged young four or five days old. 
March 30, 31; Tagus Cove, Albemarle. I observed one or two birds of 
the year at the base of the mountain, 
April 2; Tagus Cove, Albemarle. One young one seen. 
April 12; Banks Bay, Albemarle. Young plentiful. 
April 13, 14; Banks Bay, Albemarle. Many young. 
May 31; Black Beach Roads, Charles. Rather common, few adults. 
September 19; South Abingdon. Mr. King found a nest with young. 
September 21; South Abingdon. One or two very young birds seen. 
This species travels from island to island to a certain 
extent. One was taken on September 24 at Wenman, an 
island from which it has not been reported. On May 23, 
when three or four miles west of Charles a bird-of-the-year 
alighted on board the schooner. It apparently came from 
Charles and seemed to be headed towards Albemarle or 
Indefatigable. Two Jamaican Yellow Warblers were also 
seen travelling in the same direction. This was during the 
calm season of the year, as were-also the next two instances. 
An immature one alighted on the vessel on June 6, when 
about 20 miles south of Brattle. I caught it in my hand.
