Avian Use of Agricultural Areas as Migration Stopover Sites: A Review of Crop Management Practices and Ecological Correlates

Abstract: An estimated 17% of migratory bird species are threatened or near threatened with extinction. This represents an enormous potential loss of biodiversity and cost to human societies due to the economic benefits that birds provide through ecosystem services and ecotourism. Conservation of migratory bird species presents many unique challenges, as these birds rely on multiple geographically distinct habitats, including breeding grounds, non-breeding grounds, and stopover sites during migration. In particular, sto… Show more

“…Finally, an aspect that may be decisive in determining home range and foraging habitat selection patterns in birds is whether the habitat is modified by agriculture. Over one third of all bird species use agricultural areas to some extent, particularly during the non-breeding season, and seeds, cultivated plants or weeds and animals associated to crops may represent a very relevant fraction of food resources for some species [ 26 , 27 ]. It is therefore of high interest to determine to what extent the use of agricultural resources can influence the size of the home range and the selection of foraging habitat, particularly considering that croplands represent a large percentage of global land cover and are continuing to expand rapidly [ 28 ].…”

“…Forests worldwide are being reduced to biologically-impoverished remnants (Laurance and Bierregaard, 1997) embedded in agricultural countryside (Daily et al, 2001;Şekercioğlu et al, 2019) -croplands, pasture, gardens, open second growth, and a scattering of forest fragments, riparian strips, and remnant trees. Even though human-dominated areas are the preferred habitat of fewer than 1% of the world's ~ 11,000 avian species (Şekercioğlu et al, 2004), about a third make some use of such habitats (Şekercioğlu et al, 2007), including many temperate-tropical migratory birds (Blount et al, 2021) that are increasingly threatened with extinction (Horns and Şekercioğlu, 2018). Tropical agricultural countryside can even favor generalist species by providing them with additional food resources (Clough et al, 2011;Fahrig et al, 2011).…”

“…Bird migration is one of the most studied types of animal movements in the world, with billions of birds annually traveling between breeding and non-breeding grounds in North America alone (Dokter et al 2018). Migratory birds, which can spend up to one-third of each year migrating (Mehlman et al 2005), typically break up journeys of up to thousands of kilometers between wintering and breeding grounds by utilizing multiple stopover sites along their migratory routes (Mehlman et al 2005, Blount et al 2021, Roques et al 2022. However, in recent decades there have been significant declines in neotropical migratory birds in North America (Robbins et al 1989, Nebel et al 2010, Rosenberg et al 2019, with an estimated 13.6% decline in nocturnal migratory biomass contributing to a predicted net loss of 2.5 billion birds since 1970 (Rosenberg et al 2019).…”
