Coyotes on Campus

The message has been updated to reflect reports of coyote interactions on campus. 

A recent and sustained increase in the presence of urban coyotes on our campus and surrounding streets has prompted concern from several community members. Importantly, Caltech Security has recently learned of separate incidents on and near the perimeters of campus where a pet was attacked by a coyote.

Caltech Security takes seriously these reports and requests assistance monitoring and promptly reporting coyote interactions to Caltech Security by phone (call 626-395-5000; Ext. 5000) or online.

Please remain aware of your surroundings at all times and maintain a distance from wild animals. These steps will help ensure the safety and well-being of campus community members, family pets, and local wildlife.

Additionally, the Institute is working with the City of Pasadena and the Pasadena Humane Society to develop and implement a comprehensive plan to address and further manage coyote activity. Information that we receive from the community will inform further campus interventions, including, but not limited to the installation of wildlife cameras and signage. We will continue to make available educational material and resources for safely sharing habitats.

At the same time, grounds crews on campus and at surrounding Caltech properties will maintain shrubbery and greenery in a manner that mitigates the establishment of coyote dens.

To help support the Institute in its response, we ask that members of the community consider the following measures:

1. Report Sightings: If you see a coyote or notice unusual activity, please report it immediately by calling 626-395-5000 (Ext. 500) or filing a report online.
2. Do not feed wildlife: To avoid attracting coyotes, avoid unintentionally feeding them. Ensure garbage bins are secured and food waste is disposed of correctly.
3. Secure Your Pets: Keep small pets indoors, especially at night; when walking pets outside, use leashes and remain vigilant.

If a coyote is encountered, scare it away by yelling, stomping your feet and waving your arms, and/or throwing rocks or other objects towards (but not at) the coyote. It is important to stand your ground and to maintain a coyote's natural fear of humans. Coyotes are generally most active during dusk, dawn, and at nighttime, particularly in the spring when they are feeding or protecting their young.

We are committed to ensuring the safety and well-being of our community and local wildlife. Your cooperation and vigilance are crucial as we implement these measures.

Thank you for your support.
