Winter Bird Diversity and Abundance in Small Farmlands in a Megacity of Southern China

Abstract: Urban expansion often accompanies a loss of natural habitats and arable lands but an increase in urban population. In China, vegetable-dominant small farmlands are common in urban/peri-urban areas. Some farmlands are also associated with government policy that aims to enhance local farmers’ livelihoods as well as increase food availability for city citizens. While small urban farmlands create open greenery cover that may provide birds with resources such as food and shelter, little attention has been given to … Show more

“…However, during the wet season, the highest species richness and diversity were observed in the farmland habitat. The reason may be that during the wet season, diverse crops at urban farmlands can benefit the feeding of some bird species by growing weeds, and different crops are good habitats for small flies and caterpillars [ 53 ]. Moreover, birds forage for insects at flowers of green onions and move around or perch on trellis and vine crops, which are relatively common in farmlands with diverse crops.…”

“…This supports the finding of previous studies that open green spaces in cities had a positive effect on birds ( Yang et al, 2015 ; Lee et al, 2019 ). In addition to the attractiveness of lawns to tourists and urban exploiters ( Paker et al, 2014 ), and as the food source of farmlands with highly disruptive ( Lee, Chen & Zou, 2022 ), tea plantations play a greater role in bird conservation, because of their close-to-natural characteristic and lower human disturbances ( Halfwerk & Oers, 2020 ). For example, compared to urban recreational functions, cannot support long-term visitors.…”

“…The size of all farmlands was ≥ 7,850 m 2 . Within a farmland, I established a 50 m-radius area (site, hereafter) that was also used for bird surveys in another study ( Lee, Chen & Zou, 2022 ). All samplings were performed within the 50 m-radius area during January each year.…”
