F. Richardson 1937 29. 3 mi. W Paulina Lake (cont.) June 19, 1937 - Direct association of birds with water can be studied to advantage in this region of little water - though the atypical rainy weather so continuous lately has made this more difficult. A pipe line sports water near camp - some 4 mi. from Paulina Cr.. A Ruby-crowned Kinglet was seen bathing at this sport. If baths are essential to the well-being of birds such a water source might be invaluable in a region of little water. Soon Solitary Vireos and Western Flycatchers have been collected near Paulina Cr. - probably an insect food relation. Robins can be found along the creek but rarely far from it. The effect of logging can be seen best in regions below camp where brush (Mangonia esp.) almost covers tract where forest must have been originally quite heavy. In this region of brush and no trees Green-tailed Towhees are common (not seen at all in surrounding forest) and Fox Sparrows are common (uncommon in surrounding forest with less brush). Evidently man has effected an increase in these species and perhaps a decrease in others in so changing the habitat conditions.
