I think we are all familiar with the scenario of the mudflat covered in
waders and terns, the off-the-leash dog chasing them all away, and the
canicidal and homicidal thoughts that this engenders.
This would be a very good example of a dog-activity that lead directly to
bird mortality. if the waders were recently returned migrants, and were
unnecessarily disturbed, then mortality could ensue.
