Nesting:
The ground nesting of harriers
sets them apart from other raptors except for nocturnal predators such as
owls (Strigidae) (Simmons 2000). Northern Harriers build there nests using
reed stems, grass, and twigs. The Harriers nesting habitat varies
depending on the type of climate, in wet areas the nesting site will
usually be in marsh areas among cattails. In dry areas the nesting site
can be found among low brush or sage (Dekker 1996). The female will
usually lay 4-5 pale blue eggs, sometimes marked with light brown spots.
The nest is made of dead reeds or grass in a marsh or shrubby meadow. The
incubation period is 31-32 days and chicks fledge at 30-35 days
(Hammerstrom1986). |
