Impacts of anthropogenic activities and habitat degradation on breeding waterbirds [PDF]
, 2013 We investigated the effects of threats on breeding waterbirds in the Gediz Delta, Turkey. Breeding Bird Surveys were conducted in 2002 and 2006. The survey area comprised 305 UTM grids of 1 x 1 km(2).

Waterbird nest survival derived from drone surveys
Journal of Field OrnithologyDrone surveys provide accurate estimates of nest abundance and survival for ground-nesting waterbird species, but drones have not been used to estimate survival for waterbirds nesting in a canopied swamp habitat. We compared nest survival of Snowy Egret (

Exploring sources of uncertainty in the estimate of waterfowl harvest in the United Kingdom
Wildlife Biology, EarlyView.There is an urgent need to gather data on harvest rates of waterbirds in Europe to assess the sustainability of hunting. Estimates of total waterbird harvest in the United Kingdom (UK) and the relative harvest of different huntable species come from two separate surveys, the Value of Shooting (PACEC 2014) and National Gamebag Census (NGC), and these ...

Habitat Utilisation of Waterbirds in and around Maduru Oya Reservoir [PDF]
, 2021 Wetlands are important bird habitats and waterbirds use them for feeding, resting, breeding and other social interactions. This study was conducted to determine the most important habitat types utilized by waterbirds to exhibit different behaviors, in ...

Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites
Wildlife Biology, EarlyView.Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Diversity of Waterbirds in the Sebuku Strait Kotabaru, South Kalimantan [PDF]
, 2015 This research is to determine the diversity of waterbirds in the Sebuku Strait (Pulau Laut Timur and Pulau Sebuku), Kotabaru, South Kalimantan. Communities of waterbirds identified in the mangrove forest (HM); rice paddies and ponds (Sw-Ta); wetlands and

Wildlife Letters, EarlyView.Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the
