Some bag limits make you scratch your head

Scaup are probably the most abundant ducks in North Dakota right now, and the May surveys had scaup as the 2^nd most abundant duck overall.

Yet bag limits remain at 1 per day – that seems odd when other species are less abundant and have higher bag limits.

Scaup numbers are 4 times higher than Redheads and 5 times higher than Canvasbacks, but those species have a two-bird limit.

Scaup are more abundant than Blue-wings, Green-wings, Wigeon, Gadwall and Shovelers, but bag limits for those species are all 6/day. 

Those numbers don’t seem to add up.
