Item #: SCP-4391
Object Class: Safe Euclid
Special Containment Procedures: Scp-4391 is to be kept in a steel triangular container at all times, with three on each wall. The container is to be kept at 150° and is not to be entered without site-manager approval. SCP-4391 is currently being kept at Site-███. A pool of room temperature water is to be placed in the container every other day. When personnel must enter the room, they are not to interact with SCP-4391 and are to wear white hats of any variety.
Description: SCP-4391 is a large adult male Trumpeter Swan (Cygnus buccinator) weighing 49.44 kilograms pounds, and is 1.85 meters long. Found in the Sewers of New York City. SCP-4391 has no uncommon genealogical features, nor does it have any anomalous phenotypic features, but is seemingly unable to fly, or does not know how to. When SCP-4391 is put into an environment with a temperature of less than 125° Fahrenheit it will begin to squawk increasing louder until it is put into an environment of 126° or higher. The highest recorded volume was [DATA EXPUNGED] decibels. If SCP-4391 is kept in a Concealed room with a temperature of 125° or lower it will begin to grow in size. SCP-4391 will continue to grow in size until it reaches a weight of 22679.60 kilograms, and a height of [DATA EXPUNGED]. Once it reaches the height of [DATA EXPUNGED] it will begin squawk. It will grow increasingly louder at an inconsistent rate. At full size it’s squawk can be heard from 1,600 Kilometers to [DATA EXPUNGED] Kilometers away. It is rarely hostile to personnel while in containment but is known to attack D-Class personnel. One recorded scenario showed SCP-4391 ripping off a D-Class personnel’s nose, see Incident 4391-18. SCP-4391 has since been reassigned, Euclid.
SCP-4391 is shown to be more tempered and seems to enter a docile state when around individuals wearing white clothing. Personnel wearing white clothing while in the containment area are said to feel a dominant force towards SCP-4391. Whether this is an anomalous feature, or not, is undetermined.
Addendum: 4391-12
SCP-4391 was originally found inside Lake Mills, Wisconsin, in the United States of America. Multiple reports of incredibly loud squawks coming from inside the town indicated the Foundation, MTF task force Eta-5 “Jäger Bombers” found and captured SCP-4391 at a height of [DATA EXPUNGED] Kilometers.

Incident: 4391-1
Following the first attempted containment of SCP-4391, SCP-4391 appeared hungry and was orally emitting an increasingly loud sound. A D-Class was sent into SCP-4391’s containment room, in an attempt to feed it. On entry, said D-Class experienced rampant pain coming from his ears. Following his evacuation. Said D-Class claimed to have a “Rampant headache”.
Incident: 4391-18
Due to Increasing amounts of violence coming from SCP-4391, it was recommended by the current site-manager [DATA EXPUNGED], that SCP-4391 should be moved to Euclid containment. When a D-Class Personnel was sent into SCP-4391’s containment room, SCP-4391 began to charge toward the D-Class Personnel and jolted its head towards him. SCP-4391 Attached his bill to the D-Class Personnel, and ripped away from his head towards the left side of his face, causing major tissue damage, and the full, unretained removal of the D-Classes nose. He began to scream, he kicked SCP-4391 in the lower breast. SCP-4391 in response honked increasingly louder and began to walk towards the middle of its containment room. Foundation personnel has since hospitalized the D-Class, he is expected to make a full recovery. SCP-4391 has since been moved to Euclid Containment and been reassigned as Euclid.
