“…Studies have revealed that geese that choose to spend the winter season in marsh habitats possess lower lipid amounts compared to those that prefer crops. This indicates that there is a higher energetic compensation for the abundance of food in agricultural areas (Fowler et al, 2020).…”

Intensive agriculture has had a negative impact on biodiversity and human health across the world. Specifically, bird populations have declined for many years due to soil degradation and agrochemical pollution. This review, which draws on 890 sources, including research articles and literature reviews, examines the interaction between birds and intensive agriculture to better understand its effects and conservation implications. Intensive agricultural activities have resulted in significant population declines among insectivorous and carnivorous birds, while generalist bird populations have increased. The heavy use of pesticides in intensive agriculture affects food availability for birds by reducing invertebrate and vertebrate populations as well as natural vegetation cover, which has a significant impact on bird diversity. Additionally, the accumulation of toxic compounds reduces bird reproductive success. In general, intensive agroecosystems have consistently had lower avian diversity than forest habitats and even lower-impact agricultural systems. However, some agroecosystems, such as rice fields, agricultural drainages, and canal systems, create alternative habitats that can benefit waterfowl. Future work should consider strategies such as restoring and enhancing vegetation edges, preserving natural vegetation, implementing organic farming practices, maintaining water bodies, and providing economic incentives for landowners to conserve biodiversity on their land to promote bird diversity conservation.

“…The seasonal habitat quality of the environment where the geese are raised also signi cantly affects their performance, reproduction and viability. By taking advantage of agricultural products in their wintering habitats, their food needs are met by the catabolism of the lipid reserves they accumulate and they contribute to an increase in survival rates (Wilson et al 2016;Fowler et al 2020). Stored endogenous nutrients are critical to the life cycle of arctic geese as they are used to supplement essential nutrients for long-distance migration, surviving harsh winters, and breeding (Massey et al 2020).…”

Unlike other poultry species, geese can benefit from roughage to some extent due to the histomorphology and physicochemical characteristics of their digestive systems. The narrowing of goose habitats due to agriculture and other reasons emphasizes the provision of a food chain in the protection of the goose population. During the winter months, the supply of roughage becomes very difficult and the cost of goose diets increases. The research was carried out to determine the possibilities for geese to spend the winter season more economically by adding roughage instead of some of the concentrated feed. Therefore, in this study, corn silage was substituted at the level of 10% (S10), 20% (S20), 30% (S30) and 40% (S40) corn soy-based mixed feed (control group: S00). The experiment was carried out in local Turkish goose variety male geese at the age of 19 weeks (for 12 weeks) in the winter season. The result showed that substitution of corn silage instead of concentrated feed at 30 weeks did not adversely affect the investigated parameters (growth performance, carcass characteristics and yield, edible internal organ weights, digestive system length and weight, chemical composition of meat, physical and organoleptic quality characteristics). On the other hand, it was determined that it affected meat quality (hardness etc.) positively. It concluded that corn silage can be used up to 40% of the mixed feed, especially in winter feeding where roughage is not sufficiently supplied. Thus, it can be said that by using roughage instead of a portion of concentrated feed in goose diets, feed cost savings can be achieved and geese can be produced more economically.

“…Individuals with lower body mass (which may result in a lower body condition) may have delayed courtship and breeding pair formation (Miller 1985, Hepp 1986). In contrast, better non‐breeding body condition in some waterfowl species increases the chances of survival and level of productivity during the following breeding season (Heitmeyer and Fredrickson 1981, Devries et al 2008, Warren et al 2014, Fowler et al 2020). Better body condition can also decrease time spent in spring migration (Dujins et al 2017), allowing migrants to reach the breeding grounds sooner, potentially increasing reproductive success (Rohwer 1992, Elmberg et al 2005, Devries et al 2008).…”

Waterfowl with more body mass and a greater body condition during the non‐breeding season are thought to be more likely to survive and have increased productivity during the following breeding season. Body mass and body condition in waterfowl should reflect the resources available to them locally. We analyzed the relationship of landscape composition on mallard (Anas platyrhynchos) body mass and body condition (mass‐wing length index) among age and sex groups. We calculated these variables from hunter‐harvested mallards during the 2019–2020 and 2020–2021 duck hunting seasons in the Lower Mississippi Alluvial Valley of Arkansas, USA. We used linear mixed‐effects models to analyze changes in body mass and body condition with changes in the percent landscape composition of water cover, woody wetlands, herbaceous wetlands, rice, soybeans, and disturbance. We found that body mass and condition of harvested mallards were positively associated with greater proportions of water cover and woody wetlands but negatively associated with greater proportions of herbaceous wetlands and human disturbance from human infrastructure. Management actions focused on providing flooded and woody wetland areas on the landscape that allow waterfowl to access food resources, while decreasing the disturbance around wetlands in the form of road density and human infrastructure, should increase body mass and body condition in mallards spending the non‐breeding season in the Lower Mississippi Alluvial Valley.
