1 TRBL was observed at the dairy on Cornelius Ave, about 1.3 km ESE of the South Marysville point location. We were unable to gain access to the specific colony location along the Feather River. This was the only TRBL we detected in the Nicolaus area. It would be worth while to make a special trip up along the levee from Nicolaus (accessible) to the confluence of the Bear and Feather Rivers.
