由於紐約市位處大西洋遷徙路線上，衝撞窗戶成為鳥類受傷的主要原因，鳥類常被窗戶後的燈光和其反射出的天空、樹木所誤導而大量與玻璃相撞，特別是在春秋兩季的[[鳥類遷徙|遷徙]]途中。紐約[[奧杜邦學會]]估計，該市每年約有9－23萬隻鳥類死於窗殺<ref>{{Cite web|last=Tremper|first=Aaron|date=2021-03-15|title=Reports of bird deaths soar as Queens residents take in nature from home|url=https://queenseagle.com/all/reports-of-bird-deaths-spike-as-queens-residents-take-in-nature-from-home|dead-url=no|access-date=2021-05-20|website=Queens Daily Eagle|language=en-US|archive-date=2021-05-20|archive-url=https://web.archive.org/web/20210520021737/https://queenseagle.com/all/reports-of-bird-deaths-spike-as-queens-residents-take-in-nature-from-home}}</ref>，大多數的撞擊是由遷徙中的鳥類所造成。<ref name=":5" /> 其他的傷亡原因則包括接觸到Lead paint含鉛油漆、雛鳥在羽化前提早離巢<ref name=":6" />、被自行車或汽車輾壓<ref name=":6" /> 、貓和犬攻擊<ref name=":7" /> 、[[鬥雞]]<ref>{{Cite web|last=Kraft|first=Amy|date=2016-02-12|title=Rooster rehab helps birds rescued from cockfighting|url=https://www.cbsnews.com/news/rooster-rehab-helps-birds-rescued-from-cockfighting/|dead-url=no|access-date=2021-05-20|website=[[CBS News]]|language=en-US|archive-date=2021-05-20|archive-url=https://web.archive.org/web/20210520031753/https://www.cbsnews.com/news/rooster-rehab-helps-birds-rescued-from-cockfighting/}}</ref>和人為槍殺等。<ref>{{Cite web|last=Saha|first=Purbita|date=2016-02-05|title=Watch a Snowy Owl Recoup From Surgery at an NYC Wildlife Rehab Center|url=https://www.audubon.org/news/watch-snowy-owl-recoup-surgery-nyc-wildlife-rehab-center|dead-url=no|access-date=2021-05-20|website=[[奧杜邦學會|Audubon Society]]|language=en|archive-date=2021-05-20|archive-url=https://web.archive.org/web/20210520031759/https://www.audubon.org/news/watch-snowy-owl-recoup-surgery-nyc-wildlife-rehab-center}}</ref><ref>{{Cite web|last=Hanson|first=Hilary|date=2016-02-11|title=A Gunshot Wound Couldn't Break This Snowy Owl's Spirit|url=https://www.huffpost.com/entry/snowy-owl-recovery-wild-bird-fund_n_56bcbb3fe4b08ffac1242714|access-date=2021-05-20|website=HuffPost|language=en|archive-date=2021-05-20|archive-url=https://web.archive.org/web/20210520031754/https://www.huffpost.com/entry/snowy-owl-recovery-wild-bird-fund_n_56bcbb3fe4b08ffac1242714|dead-url=no}}</ref>

富商的鳥類被收治後會根據傷勢狀況行分類，有些仍允許再一定時間內在開放的空間飛翔，有些會被安置於帶有棲木的布籃中或[[孵蛋器]]內。根據麥克馬洪所述，被送往野鳥基金治療的動物有一半會在康復後回到其棲息地，另一部分則會死亡或進行[[安樂死]]。有些需要長期照顧或無法放生至野外的動物會被轉移至其他地區的收容所，如[[紐澤西州]]的The Raptor Trust(猛禽信託)野鳥康復中心或紐約州北部的Zeze收容所（Zeze sanctuary）。<ref name=":0" /> 而對於已康復鳥類，放生的地點取決於牠們是否正在遷徙以及遷徙的方向。例如許多鴿子會放生在機構附近的[[中央公園]]，但正在南遷的鴿子則可能會選在[[布魯克林]]的[[展望公園 (布魯克林)|展望公園]]，原因是與中央公園和曼哈頓其他地方相比，展望公園有一條通往南方的明確路線。
