Well, we had our first round of operations last Friday night. Here is the retrospective and lessons learned.
Duck species: Muscovy Ducks
1. Ducks can see full spectrum light, into the UV bands, and a longer distance than our eyes. They see you before you see them during the day, but at night you see them before they see you.
2. ANY type of light will spook the ducks into the water, even nighttime hunting lights, because see #1. Same with lasers. The moment you light them up, they move
3. Most effective tactic was to first find a duck silhouette, sight it in the scope, quickly illuminate them with the rifle light to ensure correct species, then shoot for the head. Only muskovy ducks were targeted, and we had a completely clean operation, no migratory ducks were wrongfully shot thanks to this strategy.
4. Due to their increasing tendency to flee with time, as the ducks increased distance from us we had to switch from head shots to body shots + followup shots afterwards. Even at 35FPE, body shots often required followup shots. Shoot once, close the distance, then shoot for the head. Muscovy ducks can take more lead than Tupac, it is ill-advised to try to take one down with only body shots from a distance. Shoot once, close the distance, go for the head.
5. The ducks liked to flee to the middle of the pond where it was darkest. Strategic use of a green laser successfully harassed them to the opposite shores, where we followed up with the airguns.
6. As we pushed South then East, the ducks began to fly back to the North pond. Next time we will keep someone positioned to the north with a laser to send them back down South.
7. In all, we got 18 ducks in about an hour’s worth of active operation. There are approximately 80 more to remove.
8. Next operation we plan to position vehicles to shine headlights through the middle of the ponds, for illumination as well as discouraging the ducks from hiding in the dark centers of the pond. Perhaps spot lights or work lights are also called for to keep light on the centers of the ponds.
9. It is best to have night vision hardware for ducks - either IR or thermal - but not a hard requirement. Such hardware can be rented online if needed for $200 - $350.
