Federal agency mistakenly kills endangered, possibly pregnant Mexican gray wolf
- A federal agency mistakenly killed a 7-year-old endangered Mexican wolf named Asiza in Arizona on April 14.
- This occurred during an authorized removal targeting an uncollared wolf due to recent cattle attacks on public land.

- The cattle incidents included six deadly attacks and four injuries between March 2024 and last month, prompting the removal order.
- The killing outraged advocacy groups and endangers the Bear Canyon pack's survival, as research shows removing a breeding female destabilizes packs.
