I stumbled across some a good read and thought I would share.
http://www.ducks.org/conservation/w...ding-waterfowl-tracking-the-mallard-migration
and
In summery, biologist put GPS back packs on mallards to see when and where mallards stop during their migration.
High lights
* satellite-marked mallards completed fall migration in less than a month on average, with the majority of the birds starting their southward journey almost a month before freeze-up. In fact, 20 percent of the ducks marked in Arkansas during the winters of 2004−2007 returned south the next fall in one nonstop flight.
* The average distance traveled by satellite-marked mallards during spring migration was more than 730 miles. The average distance traveled by individual birds during fall migration was almost 875 miles.
* One of the first mallards (a drake) ever marked with a GPS satellite transmitter in Arkansas flew more than 500 miles during spring migration, from Minnesota to Saskatchewan, in only four days.
* This same bird made a remarkable one-day flight in early fall from Saskatchewan to south-central Iowa—a distance of more than 900 miles!
* Although fall migration commonly is thought of as a one-way trip, several mallards in the tracking study made south-to-north movements during fall and winter.
There is another article I am looking for, but am afraid this may time-out before I find it.
Only 32 more days until North Zone opends :smiley_cowboy:
