Tree-nesting by Peregrine Falcons in North America: Historical and Additional Records
Falco peregrinus anida típicamente en acantilados, y el anidamiento en árboles ha sido raramente reportado para América del Norte. Reportamos nueve nidos de F. peregrinus en árboles, seis en las costas norte de California y tres en el oeste de Washington, EEUU. Dos nidos fueron construidos por Haliaeetus leucocephalus y los otros fueron tocones naturales o individuos de Sequoia sempervirens con la punta quebrada (California, n = 6) e individuos de Pseudotsuga menziesii (Washington, n = 1) de gran tamaño (rango del diámetro a la altura del pecho = 1.85–5.6 m). Todos los nidos se encontraron a menos de 7.6 km de áreas costeras o de grandes ríos.Resumen
Peregrine Falcon nest sites in live trees and snags in northern coastal California, U.S.A. Upper: Nest site in a dead-top redwood near Arcata, California. The nest location was just above the mid-point of the visible portion of the tree (K. Hamm). Middle: The nest location in this snag near Arcata, California, was in the depression created by the burned-out fire scar below the old Osprey nest platform (K. Hamm). Lower: Adult Peregrine Falcon (note arrow pointing to falcon at mid-point, right side of tree) perched on redwood nest tree near Eureka, California (M. Dunkelberger).
