Two of the four studies monitoring bird populations (two replicated, controlled before-and-after studies) these found that numbers of red-cockaded woodpeckers or male greater sage grouse increased in all or some herbicide-treated areas. Increases of sage grouse were larger at two areas without vegetation control. One study considered two species: one decreased while the other showed no response. Another found that bird densities increased equally in both control and treatment areas. Three replicated, controlled before-and-after studies in forests found that nest survival was lower where herbicide was applied to exotic shrubs or deciduous vegetation. One study also found lower nesting densities. One controlled study found northern bobwhite chicks higher had foraging success in herbicide-treated forest areas.  Collected, 29 Jul 2012 14:17:01 +0100Collected Evidence: Collected Evidence: Alter artificial nest sites to discourage brood parasitismA replicated trial from Puerto Rico found that brood parasitism levels were extremely high across all nest box designs tested.  Collected, 23 Aug 2012 16:06:05 +0100Collected Evidence: Individual Study: A 12-year study of nest box utilization by black-bellied whistling ducksIndividual, 01 Sep 2012 15:29:52 +0100Collected Evidence: Collected Evidence: Alter habitat to encourage birds to leave an areaA single before-and-after study in the USA found that an entire Caspian tern Sterna caspia population moved following (amongst other interventions) the alteration of nesting habitat at the old colony site.  Collected, 06 Oct 2012 22:42:09 +0100Collected Evidence: Collected Evidence: Artificially incubate and hand-rear gamebirds in captivityA single, replicated study in Finland found that hand-reared grey partridges Perdix perdix did not take off to fly as effectively as wild-caught birds, potentially making them more vulnerable to predation from ground predators.  Collected, 13 Oct 2012 17:33:47 +0100Collected Evidence: Collected Evidence: Artificially incubate and hand-rear cranes in captivityA replicated and controlled study and a small study, both from the USA, found that hand-reared birds showed normal reproductive behaviour and higher survival than parent-reared birds.  Collected, 13 Oct 2012 17:44:21 +0100Collected Evidence: Collected Evidence: Artificially incubate and hand-rear bustards in captivity A review of a houbara bustard Chlamydotis undulata macqueenii captive breeding programme in Saudi Arabia found that there was no difference in survival between artificially and parentally incubated eggs. A second review of the same programme found that removing eggs from clutches as they were laid increased the number laid by females.  Collected, 13 Oct 2012 17:57:07 +0100Collected Evidence: Collected Evidence: Artificially incubate and hand-rear parrots in captivity Two studies from South America describe the successful hand-rearing of parrot chicks, with ten of 12  yellow-shouldered amazons Amazona barbadensis surviving for a year after release and blue-fronted amazons Amazona aestiva fledging at higher weights than wild birds. A review of the kakapo Strigops habroptilus management programme found that chicks could be successfully raised and released, but that eggs incubated from a young age had low success. A study from the USA found that all hand-reared thick-billed parrots Rhynchopsitta pachyrhyncha died within a month of release: significantly lower survival than for wild-caught birds also translocated to the release site.  Collected, 14 Oct 2012 12:29:14 +0100
