To combat the annual population of crows in Auburn, city officials will begin reaching into their arsenal to ward off the winged invaders. Auburn's City Works Department uses a "crow distress call" that gets attached to three city vehicles. The crew ventures out to areas where roosts are most concentrated, then tries disturbing them using pyrotechnics.
This program is run for 10 straight days 3-4 times a year (usually beginning & end of November & January), from the hours of 4:00 p.m. to 7:00 p.m. and again from 4:00 a.m. to 7:00 a.m.
In the past the City has tried hanging distracting ornaments in trees that were populated by crows. The ornaments were designed to divert the crows from roosting in the trees, however, they were unsuccessful. The City of Auburn has been using pyrotechnics for 5-6 years continuously, and the roosts have become significantly smaller.
