当工人拆除一座水塔的屋顶时,里面筑巢的一家小仓鸮会遭遇什么?在曼哈顿上西区,这已成为一个亟待回答、却尚无确切答案的问题。到10月29日星期四,水塔的屋顶已不复存在。施工是否伤害或驱散了任何一只猫头鹰,甚至摧毁了鸟巢本身,仍不得而知。1
CBS纽约台发布的照片和周四的视频显示,屋顶梁木裸露在外,一名工人拿着扫帚在梁木上攀行。CBS将这座水塔确定为位于西76街与中央公园西路附近的筑巢地点。这些影像证实建筑结构发生了重大变化,但无法证明其中的鸟儿遭遇了什么。1
这一点很重要,因为这里曾成为一处出人意料的社区景点。纽约市公园局称,仓鸮在该市极为罕见;专家认为,这一家是曼哈顿已知的首例筑巢记录。邻居和观鸟者曾聚集在此,观看幼鸟成长。“已知首例”描述的是有记录的历史,并不能证明此前从未有仓鸮在这座岛上筑巢。1
纽约市鸟类联盟的杰西卡·威尔逊表示,在有关施工的报道出现前一晚,这家猫头鹰还住在水塔里。她的说法指的是10月28日晚的情况,并非施工后的目击记录。她称施工发生在星期四,但屋顶被拆除的确切时间尚未得到独立证实。1
这项施工很可能干扰了仓鸮一对成年鸟和五六只刚离巢的幼鸟。
威尔逊的评估足以令人担忧,但并不能确认有多少鸟受伤、被驱散或失踪。核心问题在于,最关键的证据——施工后对这一家的观察,以及对其筑巢空间的检查——目前都无法获得。
会飞不等于已经独立
此前的观察让人得以一窥这一家的成长情况,却不能保证它们如今的命运。曼哈顿鸟类警报在10月9日的一则帖子中描述,几只幼年猫头鹰似乎已能在上西区水塔周围短距离飞行。前一晚拍摄的照片显示,似乎最多有五只同窝幼鸟,父母偶尔会前来喂食。2
到了CBS后来报道时,近期有人在水塔看到两只成年鸟和最多六只亚成鸟。威尔逊估计有五六只刚离巢的幼鸟。这些是不同时间的观察和估计,并非连续清点,无法据此可靠地计算损失。一只鸟没有出现在某张照片里,并不意味着它失踪;施工前看到一只鸟,也不代表施工后已确认它的下落。1 2
“刚离巢的幼鸟”这一说法,也不能确定幼鸟是否仍需要筑巢空间。此前的观察显示,它们虽然能短距离飞行,父母仍持续为它们送食。这些观察并未证明幼鸟离开该地点后能够独立生存。因此,关键的未解问题在于它们是否仍依赖鸟巢,而不只是它们能否离开鸟巢。2
猫头鹰一家在水塔的一个洞里筑巢。拆除屋顶改变了遮蔽这个空间的结构,但从可见的变化无法判断鸟巢是否仍完好或仍可供使用。担心它们失去庇护所是合理的;断言这一家已经失散,则超出了现有证据所能支持的范围。1
法律实际取决于什么
威尔逊表示,正在使用的候鸟鸟巢受到联邦和州法律保护,并称建筑物必须暂停靠近鸟巢的施工。她还表示,纽约市鸟类联盟已联系有关部门。“摧毁鸟巢属于野生动物犯罪,”她警告说。这些是该组织的说法,并非主管机构认定这项施工违反了法律。1
美国鱼类及野生动物管理局的指南作出了一项鲜明影像无法解答的区分。该机构表示,摧毁含有鸟蛋或雏鸟的鸟巢,或摧毁幼鸟仍须依赖其生存的鸟巢,都是非法的,除非获得适当授权。指南还允许未经许可摧毁不再使用的鸟巢。要在此处适用这一区分,必须有证据说明施工期间鸟巢是否有人使用及其状况、施工实际对鸟巢造成了什么影响,以及是否有适用的授权。15 16
因此,称这项施工理应采取野生动物保护措施,与称某项具体违法行为已经得到证实,两者之间存在重大差距。这一差距应促使人们查明事实,而不是让人安心:不确定是否造成伤害,并不能证明施工没有造成伤害。
已知
- 10月29日的影像显示屋顶已经不见;纽约市鸟类联盟评估称,成年猫头鹰一对及五六只刚离巢的幼鸟很可能受到了干扰。 1
未知
- 施工后的鸟儿去向及状况、鸟巢状况、确切施工时间线和任何保护措施,均未经核实。
后续
- 建筑方或承包商的说明,以及有日期记录的野生动物观察或检查,可以查明发生了什么,以及幼鸟是否仍有可用的筑巢空间。
CBS表示已向建筑方询问情况,但尚未获得实质性说明。没有经过核实的记录能证明施工前进行过猫头鹰调查、设立过保护缓冲区、安排过野生动物观察员,或施工后进行过检查。缺少这些记录并不能证明没有采取预防措施。同样,鸟类联盟联系有关部门,也不能证明调查或执法行动已经启动。1
目前,对开头问题的回答只能比任何关注这一家的人的期望更有限:水塔失去了屋顶,但这些罕见住户的遭遇仍未得到确认。找到猫头鹰并检查筑巢空间,比过早指责或毫无依据地保证它们只是飞走了,更有助于消除疑问。

- Workers removed the roof of a water tower where barn owls nested.
- The family had drawn neighbors and birdwatchers to an exceptionally rare nesting in the city. NYC Bird Alliance says the construction likely disturbed the adults and their young.
- What happened to the birds and their nesting space when that roof came off?
- The tower's roof beams were exposed, with a worker carrying a broom climbing across them. The owls had nested in a hole in the tower, near West 76th Street and Central Park West on Manhattan's Upper West Side.
- The roof was already absent in Thursday's images, dated October 29, 2026. Jessica Wilson of NYC Bird Alliance described construction that day. She said the tower had housed the nesting family the night before. The precise time the roof came off is still unclear.
- Wilson estimated that an adult pair and five or six fledglings were highly likely to have been disturbed. That assessment puts a family of young birds at the center of the concern. Their condition after construction hasn't been confirmed.
- Two adults and up to six adolescents had recently been seen at the tower before the construction became public. Those observations and Wilson's estimate describe a changing view of the family. They don't give a precise census from which to count missing birds.
- Earlier in October, some young owls appeared able to make short flights around the tank, while parents occasionally delivered food. Being able to fly a short distance doesn't tell us whether a young owl still needed the nesting site to survive.
- Earlier photographs captured as many as five apparent young siblings, alongside observations of two visiting parents. By the later observations, the number of adolescents seen reached as many as six. Those are sightings at different moments, rather than a continuous count of every bird.
- The New York City Parks Department says barn owls are extremely rare in the city. Experts believed this family represented Manhattan's first known nesting. That made the water tower a place where neighbors and bird enthusiasts gathered to watch the young grow.
- Neighbors expressed concern once the construction became visible. The roof had sheltered the space the owls used, so its removal changed a site people had been watching closely. Wilson said NYC Bird Alliance contacted authorities about the work.
- Wilson warned that destroying a nest constitutes a wildlife crime. She also said active migratory-bird nests have federal and state protection, and asserted that the building had to pause work near the nest. No agency has announced a violation here.
- The legal issue turns on what the construction did to the nesting space and whether birds still depended on it. Removing the tower's roof tells us that part of the structure changed. It doesn't tell us whether the nest itself was destroyed.
- Federal wildlife guidance prohibits destroying nests containing eggs, chicks or young still dependent on them, unless properly authorized. It allows destruction of inactive nests without a permit. Applying those rules here requires knowing the nest's condition and occupancy during the work.
- The guidance also recommends scheduling activities outside nesting season to avoid destroying or relocating active nests. It doesn't prescribe a blanket pause for every construction activity at this property. Any decision about this tower would need the facts of this particular nest and work.
- The building had been asked for information, but hadn't provided a substantive explanation. A confirmed work timeline and details of any wildlife precautions would help clarify what happened. A fresh observation or inspection could establish how the birds and nesting space fared.
- The roof is gone. Whether the work injured or displaced any owl, or destroyed the nest, remains unknown. The immediate concern is finding the family and determining whether the young still have the nesting space they need.
