Nesting periods

The figure presents a map of Canada showing the 27 nesting zones associated with the regional nesting periods. The nesting zones are identified by a letter A, B, C, D or N, representing broad geographical area, mainly from west to east and by a number from 1 to 10, associated with mean annual temperature variations, mainly from south to north. In addition, the map shows the boundaries of the Bird Conservation Regions (BCR) and of the provinces and territories. To help situating the limits of the nesting zones, the map shows the location of 62 municipalities and, in background, the countries neighboring Canada (parts of United-States of America including parts of Alaska, parts of Greenland and Iceland).

From west to east, the nesting zones are situated as follows: the greater nesting zone A is found in British Columbia (BC) and it includes the bird conservation region of the Northern Pacific Rainforest BCR 5, the Great Basin BCR 9 and the Northern Rockies BCR 10. It is divided in five sub-zones numbered from one to five. The zone A1 covers the southern portion of the BCR 5, including Vancouver Island and the Pacific coast, expanding north from the border with United-States (US) to half the distance in latitude between the islands of Vancouver and Haida Gwaii. The zone A1 also covers the western and eastern parts of BCR 9, expanding north from the US border to the northern portion of BCR 9. The middle portion of BCR9 belongs to zone A2 and splits the zone A1 in two disjointed portions. The town of Penticton is located at the western limit of the eastern portion of zone A1. The zone A2 covers two disjointed areas. The first one located in the south of BC, covers the middle portion of BCR 9 including the City of Kamloops and the south-western area of BCR 10 between the eastern portion of zone A1 and the Town of Kimberly. It expands north from the border with the US to the northern tip of BCR 9, except for a disjointed portion belonging to zone A1 embedded. The second portion of zone A2 is along the Pacific coast of BC, and covers the northern portion of BCR 5, including the Island of Haida Gwaii.
