ONTARIO. 



This is one of the earliest harbingers of spring, and its 

 quick querulous notes are hailed with joy, as a prelude to the 

 grand concert of bird music which is soon to follow. 



Early in April the male Pee-wee appears in his former 

 haunts, and being soon joined by his mate they at once begin 

 to repair their old nest or to select the site for a new one. 

 They are partial to the society of man, and their habits, as 

 shown in their nesting, have been somewhat changed by this 

 taste. The original typical nest of the Pee-wee, we are told, 

 was placed on a ledge under a projecting rock, over which 

 water trickled, the nest itself often being damp with the spray. 

 We still see one occasionally in such a position, but more 

 frequently it is placed on the beams of a bridge, beneath the 

 eaves of a deserted house, or under the verandah or the projection 

 of an outhouse. They raise two broods in the season, and 

 retire to the south in September.
