In the past week or so, the UC Davis Putah Creek Riparian Reserve has been loaded with migrants, with several species in larger than normal numbers. The latter include Nashville and Black-throated gray warbler, violet-green swallow (rarely here except when it rains near the coast) and today, three wrentits. Wrentits are not normal on the Reserve, but Putah Creek provides a route for them to escape the hills where the fires have been, as close as about twenty miles west of here.
Surveys at Bobcat Ranch, west of Winters, have turned up large numbers of rufous-crowned sparrows and wrentits in blue oak woodland, with the same possible explanation.
