Northern spotted owls depend on old-growth forest structure for nesting and prey, with declining populations from habitat loss and barred owl competition creating welfare concerns for the remaining 3,000 individuals.
Spotted owl welfare is inseparable from habitat welfare - animals living in degraded or fragmented habitats face chronic food stress, higher exposure to weather extremes, and reduced reproductive success. Pairs attempting to raise owlets in territories without adequate prey base experience the protracted stress of failed nesting attempts and declining adult body condition. The barred owl competition creates behavioral stress through territory contests that spotted owls typically lose. Management interventions including barred owl removal create ethical dilemmas - lethal control of one native-ish species to benefit another - with genuine welfare implications on both sides of the equation.
