Purpose - search for Say's phoebes nests from 0-4ft up usually associated with weeds and grasses or twig fork (Colin Hanisim). Mileage 59897.1 - 59933.4 Walked along the creek running NE at Duncan Trail. Saw 5 Say's phoebes, calling in vegetation along the banks. Kicked up a couple away from the creek, I presume they were feeding on grain seed or on the vetch. Found no nest. Moved through the tulips but only found white-cedar. I think the nest is in the willows next to Tulip.
