Some nights the trapping is much poorer on the same time than on others for some unknown reason. Saw an adult male Carpodacus m today the fourth me see. They are very scarce & wild. The large flocks around have seem to be composed entirely of juvenile birds. Packed up in the morning & part of the afternoon preparing to more on the arrival of the packer today, but he has not arrived yet.
