The Garden Tower is a wooden tower with inside walls of Textured 1-11 siding with the grooves running horizontally.  It measures 11" x 11" inside, measures 8' tall and stands on 2' tall angle steel legs set in a 3'x 3' x 6" concrete slab.  The top opening is reduced to 11" x 5" and located on the north side.  It was originally a single-walled tower.  However, due to problems with over-heating, a second skin with an insulated space was installed in 2000.  Nesting success since that time has been sporadic.  We now believe that this small tower is inadequate for the needs of Chimney Swifts.

OTHER AVIAN SPECIES

Of the 150 species of birds that have been documented (including "fly-overs") thirty-six species of birds have been documented nesting on or near the sanctuary, including Turkey Vultures that utilized a small cave in the depths of the canyon in 2003.  One of the two babies is pictured above.  The sibling retreated to the safety of the cave when the photograph was taken.   Following is a complete list of breeding avian species to date:
