& Management / Disease
Investigation & Control / Environmental and
Population Management / Techniques:
- Flying of a trained raptor
over the area from which bird dispersal is
|Appropriate Use (?)
- For immediate dispersal of birds which normally fly to avoid predators
(e.g. shorebirds, gulls, terns, some waterfowl. (D210.4.w4)
- Effective in hazing species such as waterfowl and gulls.
- No problem with habituation. (D10)
|Complications/ Limitations / Risk
- Only useful in daytime. (D10)
- Only useful on fair, non-windy days. (D135.3.w3)
- Requires a highly trained raptor and falconer. (D10,
- May require initial flushing if a bird (e.g. peregrine falcon) is to
be used which does not attack stationary targets. (D135.3.w3)
- Most waterbirds respond to falcons by landing on the
water or diving (D135.3.w3).
In oil spill situations, use of falcons therefore may
increase the risk of birds contacting spilled oil - particularly for
species which normally dive to avoid predation. (D10,
- Risk that the raptor could chase or disperse birds into an oiled area.
- NOT RECOMMENDED FOR USE IN OIL SPILL SITUATIONS. (D160.App3.w11)
|Equipment / Chemicals required and Suppliers
- Requires trained
|Expertise level / Ease of Use
- Experienced falconer required.
|Legal and Ethical Considerations
- Risk of increasing contact of birds with oil as they
land or dive to avoid the predator. (D10,
- Risk of the trained birds becoming oiled. (D135.3.w3.
- Permits may be required. (D135.3.w3)
