A bird repelling device has an elongate housing having a slide chamber that
extends longitudinally from a top end to a bottom end of the elongate
housing. The elongate housing also has a cap positioned adjacent to the

the cap. The bird repelling device also includes a slide mechanism that is
adapted to slidably engage the slide chamber to slide between a retracted
position and an extended position. A plurality of bird repelling rods are
each attached to the slide mechanism and extend through one of the
plurality of rod apertures. The bird repelling device also includes top
and bottom attachment loops for attaching the bird repelling device to a
