参加前先确定一个安全、可重复的样线
活动日期是10月10日，但不要求全天移动或追逐热门鸟点。优先选择熟悉、公开开放且有明确入口和退出路线的公园或湿地；团队提前约定集合、结束、失联和恶劣天气方案。
把路线控制在能认真记录的范围。分散到多个普通样点，比大量人员围到一个稀有鸟位置更有公民科学价值，也能降低惊扰、停车和安全压力。
一份可信清单需要哪些字段
记录准确的开始时间、持续时长、步行或行车距离、参与人数和观察方式，并尽量提交完整清单：不仅写目标种，也写观察期间能够确认的常见种。重复看到的同一鸟群不要在相邻点机械相加。
数量无法精确时使用谨慎估算，并在备注说明方法。声音证据、照片和行为描述可辅助审核，但不确定的鸟保留到属、科或未定层级；不要为了把清单做长而猜测。
活动日也必须保护敏感位置
不开鸟鸣回放、不投喂、不用活饵、不飞无人机、不跨越围栏和封闭线。鸟群连续抬头、停止取食、改变方向或惊飞说明距离过近，应立即后退。
朱鹮、黑鹳、猛禽巢区及其他敏感记录不公开实时坐标。可将原始资料定向提交给有管理责任的平台或机构，公开分享时删除照片定位、延迟时间并模糊地点。
Choose one safe, repeatable route first
The event is on October 10, but it does not require all-day travel or chasing popular pins. Prefer a familiar, publicly open park or wetland with clear entrances and exits. Teams should agree meeting, finish, lost-contact and severe-weather procedures in advance.
Keep the route small enough to record carefully. Distributing observers among ordinary sites produces more useful citizen-science coverage than crowding one rarity, and it reduces disturbance, parking and safety pressure.
What makes a credible checklist
Record an accurate start time, duration, distance, party size and observation method, and submit a complete checklist when possible: include all confidently detected common birds, not only targets. Do not mechanically add the same flock again at an adjacent point.
When an exact count is impossible, make a conservative estimate and explain the method. Sounds, photographs and behaviour can support review, but an uncertain bird should remain at genus, family or unidentified level. Never guess to lengthen a list.
Sensitive locations remain protected on event day
No playback, feeding, live bait, drones, barrier crossing or entry into a closure. Repeated head-raising, interrupted feeding, directional change or flushing means the observer is too close and must retreat.
Do not live-share coordinates for Crested Ibis, Black Stork, raptor nests or other sensitive records. Original evidence may be submitted privately to a responsible platform or institution; public posts should remove image location data, delay the time and generalize the place.
