Mr. J. J. Quelch (Timehri (2) x. p. 262), writing on the 

 Migratory Birds in British Guiana, remarks : — " Even as regards 

 the birds obtained on or near the coast, belonging to species that 

 are migrants in the north, it is not always possible to determine 

 whether they are true migrant forms here or not. So little is 

 known locally about many of our species, especially of the 

 smaller kinds, that there is no comparison possible as to their 

 relative abundance in the different parts of the year ; and though 

 it would seem that species occurring here in the summer are resi- 

 dents, yet where only one or two specimens have been noted tjiey 

 may possibly be migrants that have remained behind. There is 

 this difficulty in the case as regards the Water Thrush (Seiurus 

 ncBvius), which is a common migrant in the northern regions.^'
