They were checked periodically until about mid-night. Perognathus longimembris was the only species caught (5 of them). At least 2 sidewinders were seen during the evening by those checking traps. The Peng. was toe-clipped & released. I took two groups out night collecting. The first group drove along the Rio del Sol road from Rancho Mirage to 1000 Palms, then along the old highway from 1000 Palms to Barnett and return to 1000 Palms + Rio del Sol.
