鸟类摄影是一种流行且不断发展的生态旅游形式，有助于当地社区的经济增长，但其对鸟类繁殖的干扰仍未得到充分研究。我们在中国南方的热带森林里拍摄，近年来，那里的摄影师数量急剧增加。我们比较了被拍照的巢穴和没有拍照的巢穴的捕食情况和亲代的进食率。包括42个物种的巢穴，结果表明，未拍照的巢穴（孵化期：194个巢穴中的43.3%；雏鸟期：110个巢穴中的34.5%）的捕食率显着高于拍照的巢穴（孵化期：83个巢穴中的2.4%；雏鸟期：81个巢穴中的11.1%）。在不同的巢类型中，灌木和树木中的开放杯巢在孵化和雏鸟阶段受摄影的影响最大。在调查的五个因素中，包括三个自然因素（巢穴阶段、结构和位置）和两个人为因素（摄影和到森林边缘的距离），只有摄影干扰和巢结构具有显着影响（开放巢穴具有更高的捕食性）。当摄影师在场时，巢穴的进食频率与摄影师不在场时没有太大差异。因此，人类活动对鸟类没有负面影响，但在降低巢穴捕食率方面对它们的筑巢成功产生了积极影响。然而，在了解鸟类摄影的总体效果之前，需要进一步评估筑巢的其他方面（例如窝数、雏鸟在巢中的持续时间）和其他类型的应激反应（例如荷尔蒙变化）。
Bird photography is a popular and growing form of ecotourism that contributes to the economic growth of local communities, but its disturbance to bird reproduction remains understudied. We worked in a tropical forest of southern China, which has experienced a sharp increase in the number of photographers in recent years. We compared nests that were photographed and those that were not, in their nest predation and parental feeding rates. Including nests of 42 species, the results demonstrate that the predation rate of nests that were not photographed (incubation stage: 43.3% of 194 nests; nestling stage: 34.5% of 110 nests) was significantly higher than that of photographed ones (incubation: 2.4% of 83 nests; nestling: 11.1% of 81 nests). Among different nest types, open cup nests in shrub and trees were most affected by photography, in both incubation and nestling stages. Of five factors investigated, including three natural factors (nest stage, structure and position), and two anthropogenic factors (photography and distance to forest edge), only photographic disturbance and nest structure had significant effects (open nests had higher predation). The feeding frequency at nests when photographers were present was not strongly different from when they were not present. Human activity therefore had no negative effects on the birds, but showed a positive effect on their nesting success, in terms of reducing nest predation rates. However, there needs to be further assessment of other aspects of nesting (e.g., clutch size, duration of nestlings in nests), and other kinds of stress responses (e.g., hormonal changes), before the total effect of bird photography can be understood.
