Nest survival data confirm managed housing is an important component to the conservation of the eastern purple martin

Wildlife Society Bulletin, 2019
The purple martin (Progne subis) is entrenched in a consistent, long‐term decline. This is especially true for the subspecies east of the Rocky Mountains (P. s.

Research activity does not affect nest predation rates of the Silver-throated Tit, a passerine bird building domed nests

Avian Research, 2020
Background Research activities have often been thought to potentially influence avian nesting success by increasing nest predation rates. Although recent studies of species building open nests and cavity nests suggest that research disturbance does not ...

The feeding and breeding ecology of little blue penguins (Eudyptula minor) from Tiritiri Matangi Island, New Zealand : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in Conservation Ecology, Massey University [PDF]

, 2006
At present the New Zealand populations of Little Blue Penguins (LBP: Eudyptula minor) are classified as 'Threatened' and in 'Gradual Decline' by the Department of Conservation. Effective conservation management of the North Island sub-species requires an

Development of the Innate Immune Response in NestlingTree Swallows (Tachycineta bicolor) [PDF]

, 2009
The innate immune system provides an immediate, short term, first line of defense from pathogens; its appearance early in development in vertebrates is evidence of its critical importance.

Meadow birds on organic and conventional arable farms in the Netherlands: abundance and nest success [PDF]

, 2010
Intensification of agriculture is mentioned to be the key drive behind the decline of farmland birds on grassland and on arable land. This raises the question whether a less intensive system, such as organic, can stop or reverse these declines.

Waste management in the stingless bee Melipona beecheii Bennett (Hymenoptera: Apidae) [PDF]

, 2014
Waste management is important in insect societies because waste can be hazardous to adults, brood and food stores. The general organization of waste management and the influence of task partitioning, division of labor and age polyethism on waste ...

Sparrow nest survival in relation to prescribed fire and woody plant invasion in a northern mixed‐grass prairie

Wildlife Society Bulletin, 2017
Prescribed fire is used to reverse invasion by woody vegetation on grasslands, but managers often are uncertain whether influences of shrub and tree reduction outweigh potential effects of fire on nest survival of grassland birds.

Nesting Mottled Duck ( Anas fulvigula ) selection of ungrazed grasslands in southwestern Louisiana is associated with increased nest survival

Avian Conservation and Ecology
Nest site selection is a discrete and often repeated choice, and individuals should select nest sites that maximize reproductive success and thus increase fitness.
