Conservation Status
The Eastern Loggerhead Shrike (L.l. migrans) is critically endangered in Canada. (Although only one island subspecies is legally listed as endangered in the United States, the species is declining continentwide and no longer occurs in most of the northeastern U.S.) A captive population was established at the Toronto Zoo and McGill University in 1997. In 2001 an experimental field breeding and release program managed by Wildlife Preservation Canada was established. "Field breeding" refers to moving captive pairs from their wintering cages at the Toronto Zoo and McGill to large enclosures within shrike habitat in Ontario where the pairs nest and raise their young and then the young are released to the wild when they'd naturally disperse from their parents. Since 2004 over 90 young have been released annually and between 2% and 6.5% of young released have successfully migrated and returned to breed in the subsequent year.

“The influx of women into paid work and her increased power raise a woman’s aspirations and hopes for equal treatment at home. Her lower wage and status at work and the threat of divorce reduce what she presses for and actually expects.”
