3 mi. W Paulina Lake (cont.) June 18, 1937 - We have had good opportunity to-day and on past days to compare collecting in rain or drizzle, in cloudy weather, or in sunny or intermittently sunny weather. The fact becomes unmistakable that collecting becomes much more difficult when weather is raining or continually cloudy. We may grant that birds are generally actively feeding in bad weather but yet, and especially in forested or brushy country, we can best find birds by their songs and call notes. These songs and calls are noticeably diminished or quite absent in bad weather. Call notes may occasionally be heard in bad weather when no songs are heard, but even calls may be nearly unheard in steady rain when birds generally seek protection and are quiet vocally and physically. - The depression of bird song by bad weather has no lasting vigor effect on this song for song may be started with full vigor or suddenly starting. A comparison of singing at night to singing in the rain might be appropriate for each seems to illustrate instinctive action occasionally so strongly urged as to take place under abnormal conditions.
