I have recently mad a list all the birds on the all time Alberta list and categorized them into 6 categories.
Code 1. Abundant seen with out much effort every year.
Code 2. Range restricted species more effort if required to find.
Code 3. Very localized breeders and migrants and expected rarities
Code 4. Very rare breeders and accidentals
Code 5. Extremely rare bird less that twenty records.
Code 6. The most rare less that five records.
