  • Pacific mistletoe (Phoradendron villosum) is a parasitic flowering plant that grows on several species of oak trees in the western United States.
  • The fruits of Pacific mistletoe are eaten by birds and the sticky seeds are spread throughout the landscape by frugivorous (fruit-eating) birds.
  • However, there is little to no documentation of which bird species feed on the mistletoe.
  • You can help broaden our understanding of how this mistletoe spreads and how it effects bird communities by reporting any sightings of birds foraging on mistletoe in the Willamette Valley using this form.
