This is a most surprising report. Does anybody else have definite sightings
of Pacific-slope Flycatcher yet?  

The 3/11 early date (based on Shuford) needed correction, so I checked
other sources.

"Monterey Birds" 2nd edition by Roberson has the earliest arrival for 20
years of data as 3/2 in Carmel.  A 2/25 record near Elkhorn Slough was
treated as a straggling winter bird.  

Bolander's data from Santa Rosa over 26 years has 3/8 as the earliest
Pacific-slope.  

In Santa Cruz County, the earliest on record is 3/5 based on 33 years of
data.  See: http://santacruzbirdclub.org/Spring%20Arrival%20Dates.htm

3/11 is the earliest arrival I could find for Santa Clara County:

Unitt reported the earliest arrival in San Diego County as 3/3.  

Patten et al. reported earliest arrival at the Salton Sea as 3/15. 

Marshall et al. reported earliest arrival in Oregon as 3/5.

Based on all these sources, I am comfortable moving up the earliest on
record date for our area to 3/2.
