Abstract

The breeding period of birds is a critical and sensitive portion of the annual cycle. Understanding how human use of urban green spaces affects nest survival can improve our understanding of conserving breeding bird populations in cities and support science-based management of urban green spaces that benefit both people and nature. We conducted a nest survival field study between April and August of 2023 in multiple green spaces in Montreal, Quebec, Canada, the country's second-largest city. We asked whether human presence (distance to trails and amount of human activity) influences the nest survival of four common open-cup nesting bird species: American robins (Turdus migratorius), gray catbirds (Dumetella carolinensis), Northern cardinals (Cardinalis cardinalis), and yellow warblers (Setophaga petechia). We also asked if variables traditionally associated with nest survival, such as vegetation concealment and seasonality, would influence nest survival. Our analyses surprisingly revealed no significant influence of human activity, vegetation concealment, and seasonality on nest survival for our target species. We found for nests that did fail, nests established during the earlier part of the nesting period failed faster. American robin nests were the most successful of our study's four target species, whereas Northern cardinal nests were the least successful. Within the limitations of our study system, our findings suggest that human presence on trails is not negatively impacting the nesting success for our target bird species using urban green spaces. Our study provides integrated science advice to land managers so they can support opportunities for people to connect with nature without causing trade-offs with biodiversity conservation.

人类的娱乐活动不会影响城市绿地中开放杯状鸟巢的存活率。
鸟类的繁殖期是一年周期中一个关键而敏感的阶段。了解人类对城市绿地的利用如何影响鸟巢的生存,可以提高我们对保护城市繁殖鸟类种群的理解,并支持以科学为基础的城市绿地管理,使人类和自然都受益。我们于2023年4月至8月在加拿大第二大城市魁北克省蒙特利尔的多个绿地上进行了一项鸟巢生存实地研究。我们询问人类的存在(到小径的距离和人类活动的数量)是否会影响四种常见的开杯筑巢鸟类的巢生存:美洲知更鸟(Turdus migratorius)、灰猫鸟(Dumetella carolinensis)、北红雀(Cardinalis Cardinalis)和黄莺(Setophaga petechia)。我们还询问了传统上与巢穴生存相关的变量,如植被隐蔽性和季节性,是否会影响巢穴生存。令人惊讶的是,我们的分析显示,人类活动、植被掩蔽和季节性对目标物种的巢穴生存没有显著影响。我们发现,在筑巢期早期建立的巢失败得更快。美洲知更鸟的巢是我们研究的四个目标物种中最成功的,而北方红衣主教的巢是最不成功的。在我们研究系统的限制下,我们的研究结果表明,人类在小径上的存在并没有对我们的目标鸟类在城市绿地上筑巢的成功产生负面影响。我们的研究为土地管理者提供了综合的科学建议,使他们能够支持人们与自然联系的机会,而不会造成与生物多样性保护的权衡。补充资料:在线版本提供补充资料,网址为10.1007/s11252-024-01669-0。

期刊介绍: Urban Ecosystems is an international journal devoted to scientific investigations of urban environments and the relationships between socioeconomic and ecological structures and processes in urban environments. The scope of the journal is broad, including interactions between urban ecosystems and associated suburban and rural environments. Contributions may span a range of specific subject areas as they may apply to urban environments: biodiversity, biogeochemistry, conservation biology, wildlife and fisheries management, ecosystem ecology, ecosystem services, environmental chemistry, hydrology, landscape architecture, meteorology and climate, policy, population biology, social and human ecology, soil science, and urban planning.
