re: What do you attribute the migration change to?

Also, pressure absolutely affects duck migration

i can only speak to the wax lake/atchafalaya bay area. ive hunted it since i was a kid, well over 40 years.

before it blew up as a popular area, the ducks were highly predictable:

1) fly offshore in the morning
2) fly inshore in the evening

we could catch them coming, or going, or both.

now...they spend the day (hunting hours) massed up in gigantic mobs floating out in the bay, not flying. my assumption is they are flying at at night but who knows. bottom line is, where i hunt, pressure has changed their behavior
