The colony of birds were at -122.1112910, 39.2760843 (NAD83). Some of the birds were carrying material, but we were not able to clearly determine if it was food or nesting material. The material seemed more balled-up, so it was likely food. It wasn't clear what the colony was doing. More females were visible than males. Brian Acord and Krysta Rogers.
