Range Chatham, Charles, Hood, Barrington, Indefatigable, 



Duncan, Jervis, James, Albemarle, Narboro, Abingdon and Bindloe. 

 (Absent on only Wenman, Culpepper and Tower.) 



Our specimens are from Narboro, Albemarle, James, Abingdon, 

 Bindloe, Hood and Chatham. No local variations have ever been 

 discovered in this species; it is one of the few peculiar land birds 

 which are the same on all the islands within its range. 



We found the species rather common wherever it occurred, but it 

 was probably more abundant at Iguana Cove, Albemarle, than at any 

 other locality. The notes they generally uttered consisted of a liquid- 

 sounding whit-wktt, sometimes varying to whtt-wee, the note so com- 

 mon to all small flycatchers. The nidification and eggs are unknown.
