1. Classic standard mist‐netting limits sampling to understorey birds flying <3 m above‐ground level. Methodological innovations targeting higher strata birds (and bats) are important for ecological studies, particularly in tropical forests.
2. I present and evaluate a method of applying elevated mist‐net frames (EMF) up to ~25–30 m. I designed detachable mobile alloy frames for standard‐sized 3 × 6 m mist‐nets, weighing ~11 kg including fittings, and suspended by three‐point cable‐wire mounting. State‐of‐the‐art archery and fishing gear are employed for securing anchor lines, with hoisting applied by pulley, ropes and guys.
3. Elevated mist‐net frame is assembled and detached by two–three team members within 15–20 min, and up‐down hoisting lasts 1–3 min. EMF excludes tree‐climbing and arboreal platforms, through versatile manoeuvring in lightly cluttered naturally open corridors. EMF costs are source and quantity dependent, and feasible to institutions and grant beneficiaries.
4. Elevated mist‐net frame is a workable alternative or supplement to existing elevated mist‐netting applying poles, ropes and pulleys, owing to strength and durability, replicable construction and versatile manoeuvrability in upper strata. The EMF design demonstrates favourable prospects for high‐tech development, thus further innovations are recommended.

高架雾网框架：坚固而灵活的可操纵设计，用于捕获上层鸟类

1. 经典的标准薄雾网将采样限制在地上飞行高度低于3 m的地下鸟类。针对高地层鸟类（和蝙蝠）的方法学创新对于生态学研究特别是在热带森林中非常重要。
2. 我提出并评估了一种应用高达约25–30 m的高架雾网框架（EMF）的方法。我为标准尺寸的3×6 m薄雾网设计了可拆卸的移动式合金框架，包括配件在内重约11 kg，并通过三点电缆线架悬挂。采用最先进的射箭和渔具来固定锚线，并通过滑轮，绳索和拉索进行吊装。
3. 2-3个团队成员在15至20分钟内组装和拆卸高架的雾状网架，而升降过程则持续1-3分钟。EMF通过在杂乱无章，自然开放的走廊中进行多功能操纵来排除攀树和树木栖木平台。EMF成本取决于来源和数量，并且对于机构和补助受益人而言都是可行的。
4. 高架式雾网框架由于强度和耐用性，可复制的结构以及上部地层的多方面的可操作性，是对现有的高架式雾网应用杆，绳索和滑轮的可行替代方案或补充。EMF设计展示了高科技发展的有利前景，因此建议进一步创新。
