De Buechcllis 1964 12 Feb. Puerto Saurez, Espambta (Hood) Island, Galapagos. Heons along the shore. One was very brown and won, hardly showing the light speckles; when I charred it away it flushed a small crest which it carved and ate. The other Heon was the same dark color as the Fernandina juvenile. Saw no adult Heond one in the evening. Heard lots of Boobis and 1 Mockber (very briefly) during the night while finishing my notes. A very full day. Goats fairly common. Ted Papupuss shot 5 and I even managed to see a swallish brown one and heard several others. 13 Feb. woken up some time after sunlight. Culbides and the Geospiza and mockers all singing quite a bit, the Geospiza soon almost completely quieting. Voices from the boobis fairly conspicuous but not overpowering. Close at hand heard only Blue feet. Very little sign of Swallows-tailed Grulls. After breakfast went out to shot some finches, but my skates, went very bad, got 4 birds with 15 shots (pistol) and hit 2 with stones, only able to retrieve one. I took only Geospiza taking a ? fuliginosa from in a mesquite bush. Most of the fuliginosa I saw was in the bushes 2-4ft from the ground, and the stomachs of this bird was full of seeds of this plant and (Croelia) buds, and very much sand granules (1/8mm. fin diameter). My initial impression that this species is in the bushes much more than conirostris, but this may be due to the ratio of the two species, near like 1 fuliginosa for every 6-8 conirostris. The species is singing a little, the song fairly high pitched, like on Santa Cruz, which
