A warm rain 1:15 P.M. Still raining--a very warm rain. (Temp.67). Indoor temperature 72. Due to greater humidity outside, the sensation immediately on stepping out of doors is one of greater warmth, and on coming inside, it feels slightly chilly. Yet it is 5 degrees warmer inside. The difference feels more than that in the opposite direction. Effect of humidity. oil gland. These three road-runners have what appear to be extremely small oil (or preen) glands for the size of the bird, suggesting that they are adapted for a climate where little oil is needed for the feathers, and this, I suppose, means arid conditions. The road- runner is, of course, most frequently found in arid regions. Use of oil gland. I have had many opportunities to watch the birds use this gland at short range. One such occasion was when Archie decided to take up a permanent residence on my knee this morning. He would nibble the nipple, beginning near the tip of his bill working toward the gape. The little bead of oil which was left at the nipple was usually wiped off on his cheek and ear coverts and then applied to his plumage wherever deemed necessary. He did not object to my removing the drop with a finger. Repetition of color test. Disturbing factors. About 3 P.M. I made another rough test of the young birds' reaction to the same red roses. This proved somewhat abortive as Rhody took it upon himself to come to the cage at the same time, casing a mild amount of excitement, and a nearby bon-fire began to crackle fiercely simultaneously arousing a certain amount of fear in the youngsters. It was noted, however, that while they showed nothing like a panic, there was avoidance of the immediate vicinity of the flowers and they kept away from me as long as I held them. Rhody, on the other hand, did not hesitate to take food from me under the same conditions. Terry was the shy one. It was he who incurred the most damage yesterday. The flowers (including some scarlet penstemons) were placed at points usually most fre- Red avoided. R indifferent. T shiest.
