. Ground coverage for the breeding pair count included most of the 
important areas checked in other years. Ordinarily ground surveys contribute 
important data on broods, but this year aerial coverage received the major share 
of attention in the production survey. Webster and Boyer covered most of the 
important areas this year that were surveyed last year and ran several new cross- 
country transects and shoreline cruises. 
Crissey and Addy covered the important overland and shoreline transects 
which were established on spring surveys in the Maritimes during the past few 
years. In addition, special new transects were established in the New Brunswick- 
Nova Scotia border area, the St. John River below Fredericton, and the highlands 
in southwestern New Brunswick. Only the surveys on Prince Edward Island are 
comparable with spring transects run last year in the Maritimes. 
Since aerial coverage last year was limited to the Maritime Provinces 
the transects this year in Ontario, Quebec and Labrador are new although some 
surveys north of the Maritimes have been made in other years. 
Aerial surveys north of the Maritimes in past years are as follows: 
1949 - coverage of Anticosti Island and the shoreline of 
the St. Lawrence River west to Lake St. Peter and 
the Saguenay River to Lake St. John. There was 
also a special survey of the Ungava Peninsula by 
Fish and Wildlife Service personnel. 
1950 - coverage of Anticosti Island and a reconnaissance 
of the southeastern Labrador area during July. 
This year an attempt was made to sample the various major types of 
habitat from the Maritimes and southeastern Ontario north to Ungava and the 
eastern shore of Hudson Bay. The major forest types which were sampled are as 
follows, from south to north: 
Mixed Forest: includes the Maritime Provinces and the extreme 
southeastern portion of Ontario and the lowlands 
in the St. Lawrence Valley of Quebec. 
Main Boreal Forest: covers most of southern Quebec, southeastern 
Ontario and parts of southern Labrador. 
Open Boreal Forest: covers most of central Quebec and Labrador. 
Forest-Tundra: occurs throughout much of northern Quebec and 
Labrador with segments locally southward. 
Tundra: Restricted largely to the Ungava Peninsula and far 
northern Labrador. True tundra actually occurs 
locally well to the south at higher elevations. 
For the most part the terrain of eastern Ontario, Quebec and Labrador 
is suitable for flying conventional cross-country transects at 100 to 300 foot 
elevation. Mountainous country too rough for aerial transects is located primarily 
along the southern edge of the Precambrian Shield in Quebec, parts of coastal 
Labrador and parts of northern New Brunswick and northern Nova Scotia in the 
Maritimes.
