July 31 1925 Fri. For the first time today I went out on regular duty altho we did not go far. The woods near the Island was our main objective however we saw very little throughout the day. It is notable that the birds in the jungle are very quiet until the sun comes which is ftu 2: am. on this ridge. The timber is certainly warm enough before the sun comes up. We ran down one of the birds with the loud clear chat - cardinal song and found it to be a rather small little Thryophilus pleurostictus radii - (Wm). The bird was building nest of cactus Wm sort (and near a warble nest) well up in a tree. Of the four birds collected two were laying females and the other olive males. However finding the nests in the jungle is no simple task. Other birds were rather few this particular morning.
