This lively and interesting Tern was an exceedingly numerous species 

 at Sacramento, as well as about the extensive marshes of the Interior. At 

 the former locality they were seen about every pool in the outskirts of the 

 city, flitting over the surface of the water, and across the meadows, uttering 

 their harsh note of krih, krik, krik, as they flew. They were so unsuspicious 

 that the town boys often killed them with stones or clubs thrown at them 

 wlien flying.
