Visual observations of SCP-9525 are to be forbidden, all memories of SCP-9525 visuals are to be treated with amnestics, and all recordings of SCP-9525 visuals are to be deleted. Audio inside the bunker is to be recorded and monitored at all times.
SCP-9525-X instances are to be immediately removed from the SCP-9525 bunker and contained separately. New SCP-9525-X instances are to be ascribed new special containment procedures as needed.
SCP-9525-A is to be contained in an aviary without other birds. Introduction of SCP-9525-A to other wood thrushes is to be forbidden.
Description:
SCP-9525 is a window that measures 61.0 centimeters wide and 91.4 centimeters high. SCP-9525 shows its observer a visual of a monotone, dark, empty space. SCP-9525 reflects light as silicon dioxide glass does.
SCP-9525-X instances are anomalies whose creation is attributed to interactions with SCP-9525.

A minute later, she jumped past it while carrying fibrous materials and jumped out of the shed. | Confirmed that baseline female wood thrushes built nests on their mates' territories using fibrous materials and mud. |
| May 13, 2025 | A male wood thrush jumped into the shed and looked at SCP-9525. He attacked it for an hour, then jumped out of the shed. | Found no confirmation that baseline male wood thrushes skipped their dawn or dusk singing and attacked windows instead. Requested an inspection of SCP-9525 containment. |
| May 20, 2025 | A male wood thrush jumped into the shed and attacked SCP-9525 for an hour. Meanwhile, a female wood thrush jumped into the shed, looked at him, and then jumped out of the shed. When finished, he lethargically jumped out of the shed. | Found no confirmation that baseline male wood thrushes stopped singing in their territories altogether and attacked windows at dawn and dusk instead. Requested a reevaluation of SCP-9525 containment procedures. |
| May 23, 2025 | A male wood thrush jumped into the shed, attacked SCP-9525 for an hour, then jumped out of the shed, all while exhibiting lethargic movement. | Confirmed that baseline birds' health deteriorated while they repeatedly attacked windows. |
| May 26, 2025 | A male wood thrush lethargically jumped into the shed and looked at SCP-9525 for an hour. Meanwhile, a female wood thrush jumped into the shed, looked at him, then jumped past him. A minute later, she jumped past him while carrying an insect and jumped out of the shed. | Found no confirmation that baseline male wood thrushes stopped gathering food to their mates' nests and stared at windows instead. Requested containment and veterinary care for the wood thrushes. |
| May 29, 2025 | A male wood thrush lethargically jumped into the shed. He looked at SCP-9525 and attacked it. A sudden, loud, high pitch sound occurred and the audio and video surveillance equipment failed. | Alerted security to a possible containment breach of SCP-9525. |
