- Habitat loss and fragmentation on the breeding grounds pose the greatest threats to the loggerhead shrike.
- Intensive agricultural practices have converted native grassland with shrubs and shelterbelts to cultivated fields, resulting
in the loss of suitable breeding and wintering habitats.
- Other threats to this species include:
- Pesticide contamination
- Mortality on the wintering grounds
- Climate change
- Increased predation upon shrikes near roadsides and fencerows
- Increased competition with similar species
- Human-caused disturbance while nesting
- Under Alberta's Wildlife Act, the Loggerhead shrike is designated as a non-game animal. It is illegal to kill or
harass individuals or disturb their nests at any time of the year.
- A detailed inventory is carried out for this species every five years in Alberta.
