Miscellaneous Notes

- On 15 November 2018, the Seaside City Council in central California approved a permit to have a floating Heermann's Gull nesting island put in place at Roberts Lake.
- Six California Gulls were observed at a water treatment plant in Culberson County, Texas on 24 November 2018. To my knowledge this is a single site high count. Observers Martin Reid, Sheridan Coffey, Willie Sekula.
