SLIDE 43 Mitigation Plan Start Mid - late Nov
USDA Wildlife Biologist confirms: * Nests empty of
fledglings, and; * Any remaining eggs are not viable
Habitat Modification (up to 3 weeks) Late Nov - early Dec
CoSA Parks starts habitat modification:
* After USDA approval * Clear underbrush * Canopy reductions
Discourage Re-roost Early - mid Dec Monitor Site / Re-mitigation
Post-Mitigation
* USDA monitors relocation/continues mitigation if needed * CoSA Parks to seed island
Goal
New habitat(s) create bird flight paths that don’t intersect Kelly Field
Habitat Modification & Bird Mitigation Methods
- CoSA Parks does not start work before USDA clearance
- Inflatable air dancers proven & effective method
- Pyro noises: used with drones & lasers in the 2 hours before sunset;
1 or 2 pyro every few minutes, for up to 2 weeks then taper off
- Goal: train birds to associate drone/laser appears before noise to
disperse when they see the devices … shorten time needed for pyro
USDA Catalysts to Plan Start
- Confirms existing fledglings matured to
juvenile status & departed nests
- Assesses viability of eggs in nests
- New nestlings as of late Sep
- Visits weekly to check status
Elmendorf Lake Park: Bird Hazard Mitigation Plan
General Notes
- Eggs: ~ 30 days to hatch; nestlings take ~ 30
- 50 days to become fledglings
- Fledgling process takes 1 - 3 weeks
- If eggs hatch, delays plan start for ~ 60 days
- After initial re-roost discouraging ops, USDA
continues to monitor & mitigate as necessary
- Next Egret breeding season: mid-Feb 2020
USDA begins sight & noise bird repellents
Examples: * Air dancers * Drones * Dissauder lasers * Noise (pyros)
Future Habitat(s)
* Primary: encourage bird travel south -- or east * Secondary: westerly travel
