“…Our study found a positive association between trash consumption and productivity. This association has been debated in the literature because consumption of trash and other anthropogenic foods is common in Ciconiiformes globally (marabou stork Leptoptilos crumenifer (Francis et al 2021), white stork Ciconia ciconia (Peris 2003, Chenchouni 2017, woollynecked stork Ciconia episcopus (Thabethe et al 2021)), but it is also known to have some negative nutritional consequences (Peris 2003, Urfi 2011, Francis et al 2021. In south Florida, no marshnesting wood storks consumed trash and only some urban-nesting storks did, primarily in years when the hydrological condition of the marsh was moderate or poor.…”

Commuters: a waterbird provides a new view of how species may utilize cities and wildlands

Traditional classifications of vertebrates’ responses to urbanization fail to capture the behaviour of those that rely on both urban and wildland resources for population persistence. Here, we use the wood stork (Mycteria americana), a species that makes daily foraging trips up to 74 km away from its nest, as an example of a previously unrecognized response to urbanization. We monitored nests and sampled diets at stork colonies in south Florida (USA) during 2014–2020 to investigate how storks use urban habitats. We found that urban development now comprises up to 51.6% of the land cover within the 30-km core foraging area surrounding colonies and that storks access alternative prey types within these urban areas. Our results also showed that urban-nesting storks outperformed wildland-nesting storks when the hydrological condition of the wetlands was suboptimal for foraging. Though storks still require healthy wetlands for population persistence, urban habitat benefitted storks when hydrological patterns were not ideal for prey production in wildlands. This ‘commuter’ response to urbanization, whereby individuals opt to utilize both urban and wildland resources within short time periods, may apply to other vertebrates with large home ranges.

“…Many waterbird species engage in nocturnal foraging activities in addition to daytime feeding (Rojas et al 1997, Merke and Mosbech 2008, Barbaree et al 2015, Ntiamoa-Baidu et al 1998, Urfi 2011. To facilitate foraging under poor lighting conditions, these species have evolved adaptations such as larger eyes and highly developed rod cells in their retinas (Katzir andMartin 1998, Rojas et al 1997).…”

The loss of coastal wetlands represents a grave threat to waterbirds, prompting the use of artificial wetlands, such as aquaculture ponds, as a means of conservation. Aquaculture ponds are common in coastal areas and provide production value and ecological function as waterbird habitats. However, certain piscivorous birds may cause economic losses to the aquaculture industry. Different types of ponds provide habitat for various bird assemblages, and waterbirds exhibit nocturnal feeding behavior and utilize habitats distinct from those used during the day. Most waterbird surveys were conducted during the daytime, limiting our understanding of their nocturnal habitat utilization. This study conducted diurnal and nocturnal surveys on shorebirds, waterfowl, and Black-crowned Night Heron (Nycticorax nycticorax) ten times in three aquaculture ponds situated in the Cigu District of Tainan, namely fish/shrimp, hard clam, and abandoned ponds between October 2021 and November 2022. The results showed no significant difference in shorebird density between day and night. However, shorebird density in fish/shrimp ponds was significantly higher than in abandoned ponds. Conversely, waterfowl density exhibits a significant increase in abandoned ponds compared to the other two pond types, irrespective of diurnal or nocturnal conditions. Furthermore, waterfowl density in abandoned ponds was significantly higher during daylight compared to the nocturnal period. In the daytime, the density of night herons was significantly higher in abandoned ponds than in the other two ponds. Nevertheless, during nighttime, fish/shrimp ponds exhibit the highest density of night herons, significantly surpassing that found in hard clam ponds. Notably, water coverage also influences the density of both shorebirds and waterfowl. The foraging frequency of waterfowl and night herons was greater during nocturnal hours, while shorebirds did not exhibit significant variations between day and night. Consequently, this study underscores the significance of considering both diurnal and nocturnal habitats in formulating strategies for waterbird conservation.
