FIELD NOTES Doug Bell March 7, 1988 and out over the rock. It disappeared into a bright blue sky, heading east. I talked with a Canadian who had been watching the falcons. He said they were both stooping on a butes of some sort - drove it into the rock. I stayed to see if the birds would reappear, but after 1/2 hour I stopped watching the rock and began recording gulls (11:00 AM). About 50 Ring-billed Gulls & a few California gulls were scuffling about the parking lot. Got good long call recordings of Batef Ring-billed Gulls. At 11:30 I drove north on Highway 101 to check out possible collecting sites. There was a road leading out to Point Estero, but it was blocked by a gate. Some people came out, told me I should call the owner first. He was busy; so I had time to drive back to Mono Bay. Asked a couple of fishermen if they could take me out to on the ocean for gull collecting. Nobody would do it for under $100.00.0 But they did suggest I try the local dump. So I drove up there - it is the Los Osos Landfill, at 2295 Turri Ranch Rd., about 5.5 mi SE of Mono Rock. They, the people there, said I could shoot gulls, but only about closing time (3:30-4:00 PM). There were quite a few birds present. So I drove back up 101 to Point Estero, contacted the owner of the property. It is actually an abalone farm. The owner of the land is San Luis Obispo 93401) 805 528-1752}
