| mountain plover responses to deltamethrin treatments on prairie dog colonies in montana. | pyrethroid insecticides containing deltamethrin provide broad spectrum insect control that can adversely affect food supplies of insectivorous birds. i hypothesized that this could result in lowered nest survival for a ground-nesting insectivorous bird, the mountain plover (charadrius montanus), which preferentially nests on prairie dog colonies. i studied mountain plover nest survival in 2003-2010 at a small cluster of black-tailed prairie dog (cynomys ludovicianus) colonies in north-central mo ... | 2013 | 23269563 |
