The lower three quarters of Thunder Bay Region (#38) is shown above. It is part of Zone 16. All or part of the blocks named CA, DA, CV, DV, CU and DU are shown. Blocks BB, CB and DB lie north of these. Each side of these blocks is 100 kilometres long. Each block is divided into one hundred 10x10 km squares numbered from 00 to 99. The squares are numbered from the bottom left by column from 0 to 9 and by row from 0 to 9. The orange square in Block CA is designated 16CA41. The code stands for Zone 16, Block CA, Square 41 (column 4, row 1 - remember that the first column and the first row are designated as 0, not 1).
The western edge of Region 38 contains three partial blocks named BA, BV and BU. The standard blocks are 100 km squares, so the partial blocks are there to compensate for the curvature of the earth.
The coloured squares of this map (taken from the Atlas website) show the breeding evidence for the American Robin that was collected for the Atlas during 2001 and 2002. The dot in the centre means that the species was not reported in that square during the First Atlas (1981-1985).
White = not reported as of yet, TITLEhough this square is being atlassed.
Orange = Possibly breeding in that square.
Red = Probably breeding in that square.
Brown = Breeding confirmed in that square.
Breeding evidence entered from the first two years of the current Atlas shows that 141 species of birds have been recorded in Block 16CU, which includes the City of Thunder Bay. Seven observers have sent in data from 26 squares in that block. The second most species in the region have been found in Block 16DV, where 5 observers have recorded 87 species.
Members of the Thunder Bay Field Naturalists are not only actively taking part in the Thunder Bay Region - some have been atlassing in the far north and elsewhere in Ontario. Because of the small number of experienced observers and the size of the Thunder Bay Region, only a small percentage of the squares are thoroughly atlassed.
