Analysis of an Anomalous Canid Migration to Alcatraz Island
Introduction
A male coyote successfully navigated the waters of San Francisco Bay to reach Alcatraz Island in January, an event that prompted a biological investigation into the animal's origin.
Main Body
Initial hypotheses suggested the specimen had originated from the San Francisco mainland, given the proximity of approximately 1.6 kilometers. However, subsequent forensic analysis conducted by the University of California, Davis, utilized DNA sampling from scat and tracks to establish a provenance from Angel Island. This indicates the animal traversed a distance of 3.2 kilometers, a feat that National Park Service ecologist Bill Merkle characterized as a demonstration of the species' inherent resilience and adaptability. From a behavioral perspective, Camilla Fox of Project Coyote posited that the migration was likely predicated on the search for mating opportunities or the acquisition of new territorial domains. While the capacity for swimming is present in canids, the traversal of such challenging currents is noted as an exceptional rarity. Institutional concerns regarding the preservation of seabird nesting habitats on Alcatraz necessitated the deployment of camera traps and audio recording devices to facilitate the animal's capture and relocation. Despite these measures, the specimen has not been detected since late January, and its current location remains undetermined. Historically, the island's formidable currents served as a deterrent to human escapees during its tenure as a federal penitentiary, further underscoring the anomalous nature of this biological transit.
Conclusion
The coyote's current status is unknown, though it is believed to have departed the island.

The Architecture of Formal Precision: Nominalization and Latinate Lexis
To move from B2 to C2, a student must transition from describing actions to constructing states. The provided text is a masterclass in Nominalization—the process of turning verbs or adjectives into nouns to create a dense, objective, and academic tone.
◈ The Mechanism of Abstraction
Observe the shift from common narrative to academic reporting:
- B2 approach: "Scientists wondered where the coyote came from."
- C2 approach: "...prompted a biological investigation into the animal's origin."
By replacing the active verb "wondered" with the noun "investigation," the author removes the subjective human element and elevates the event to a formal scientific inquiry.
◈ Lexical Precision: The 'Latinate' Layer
C2 mastery requires the surgical use of Latinate vocabulary to specify nuance. Note these high-level substitutions within the text:
| Common Term | C2 Substitution | Linguistic Nuance |
|---|---|---|
| Source/Start | Provenance | Implies a documented history of ownership or origin. |
| Based on | Predicated on | Suggests a logical foundation or a prerequisite. |
| Movement | Traversal | Emphasizes the act of crossing a difficult space. |
| Weird/Strange | Anomalous | Denotes a deviation from a standard or expected pattern. |
◈ Syntactic Sophistication: The 'Passive Weight'
Notice the sentence: "Institutional concerns... necessitated the deployment of camera traps..."
Rather than saying "The institution was worried, so they used cameras," the author uses institutional concerns as the subject. This creates a "weighty" sentence structure where the concept (the concern) drives the action (the deployment), a hallmark of professional C2 discourse in legal and scientific writing.
