As many wildlife species, including wading birds, adapt to anthropogenic landscapes and, in some cases, exhibit altered behaviors, studies that involve capturing birds may require new methods better suited for use in urban areas and to accommodate altered animal behavior. We developed two novel techniques, a leg lasso and flip net, for capturing American White Ibises (Eudocimus albus) in urban environments in southern Florida, and also used a traditional technique (mist‐nets) in non‐urban wetland habitats. The flip net and leg lasso were developed to capture White Ibises habituated to the presence of humans. Ibises were captured in urban and wetland environments from October 2015 to August 2017 in Palm Beach, Broward, and Lee counties, Florida. We captured 6.0 ± 13.5 ibis/h with the flip net, 1.6 ± 0.8 ibis/h with the leg lasso, and 0.5 ± 2.6 ibis/h with mist‐nets. We captured larger (higher mass to tarsus length ratio) birds using the flip net and leg lasso than using mist‐nets, and captured more males with leg lassos than with other two techniques. The novel techniques we used are efficient, cost effective, easy to use, and also potentially useful for capturing other species of birds. Leg lassos and flip nets are also safe to use in populated areas for both birds and humans.

使用两种新颖的技术在南佛罗里达州的城市捕获美国白宜必思

由于许多野生动物物种（包括涉水鸟）都适应人为景观，并且在某些情况下表现出变化的行为，涉及捕获鸟类的研究可能需要更适合在城市地区使用并适应变化的动物行为的新方法。我们开发了两种新颖的技术，即腿套索和翻转网，用于捕获美国白朱鹭（Eudocimus albus）在佛罗里达州南部的城市环境中使用，并且在非城市湿地栖息地也使用了传统技术（雾网）。翻转网和腿套索被开发用来捕获习惯于人类存在的白色朱鹭。2015年10月至2017年8月在城市和湿地环境中捕获宜必思，地点位于棕榈滩，布劳沃德和佛罗里达州李县。翻转网的捕捉值为6.0±13.5 ibis / h，腿套索的捕捉值为1.6±0.8 ibis / h，雾网的捕捉值为0.5±2.6 ibis / h。使用翻转网和腿套索捕获的鸟类比使用雾网捕获的更大（质量与架长度比更高）的鸟类，并且使用腿套索捕获的雄性比其他两种技术捕获的雄性更多。我们使用的新颖技术高效，成本有效，易于使用，并且对于捕获其他种类的鸟类也可能有用。
