Physically protect nests with individual exclosures/barriers or provide shelters for chicks of songbirds
A replicated, controlled study in 1979 on saltmarshes in Florida, USA (Post & Greenlaw 1989) found that protecting seaside sparrow Ammodramus maritimus nests (located near the ground) with cylindrical metal barriers (1.5 m tall with a flexible wire canopy) increased the proportion of nests fledging young from 6% (34 nests) to 48% (42 nests). The main predators excluded were rice rat Oryzomys palustris.
