The Fox Sparrow is an early breeder. The birds arrived, 

 we were told, about the last week in April and by the first of 

 June many young were on the wing. From June 3rd to 5th 

 about a dozen nests were found, with young in various stages of 

 growth, and two others contained three fresh eggs each. The 

 majority were placed two to five feet up in stunted spruce; 

 two were located amongst the branches of fallen spruce, while 

 a few were sunk in moss on the ground. At the end of the 

 month several other nests were found containing three and four 

 eggs. These, no doubt, were second sets. Most of the nests 

 were composed of moss, rootlets, etc., with a lining of caribou 

 hair, while those placed at an elevation were usually built 

 externally with spruce twigs. The eggs are pale bluish-green, 

 spotted and blotched with reddish-brown, or uniform chocolate 

 brown.

 George's Bay.

45. Black and White Warbler. A fairly common 

 breeder, nesting in spruce woods about June 15th.

 the alders, June 7th, at Bay of Islands. A nest with four badly 

 incubated eggs was found, June 27th, in a birch tree.

 noted in some mixed woods, June 8th.

 seen during our visit. They were seen everywhere in the spruce 

 country. A nest with four fresh eggs was found, June 27th, 

 in a small spruce tree.

 the large hemlocks and pines at Bay of Islands, June 10th.

 singing every morning early around our camp at Grand Lake. 



54. Water Thrush.' Fairly abundant. A nest found, 

 June 4th, in the upturned roots of a tree. The bird had not 

 started to lay.
