Treatment of the received dataset
We imported the
received dataset
with modifications as follows to better combine with other atlases or to match publication cited above:
Chose not to include Merlin, Gray-cheeked Thrush and Snowy Owl based on normal distribution. Also not including 7 species that were observed only and show no breeding evidence. Several raptor sightings were downgraded to OB:RC, observed, raptor carrying food, based on the dataset received and confirmation from Dave Morton. The breeding codes CY, PA, CP, CE, BP, and BE included no description and were mapped as CO,CN or confirmed, adults carrying nesting material.
