ANAHU ISLAND TRIP, July 3, 1950 continued. Turkey Vulture - Probably about 8 flying about over the top of the island. Marsh Hawk - Observed a pair. Prairie Falcon - pair on cliffs and flying about over to [illegible] of island. Might have been nesting in hole seen present in rocks. Marbled Godwit - Flushed 6 from edge of island. California Gull - 2,000 adults were estimated present at the colony and in the air above it. The gull colony was at the south end of the island. An inspection of photographs of the colony [illegible] brings [illegible] forth an estimate of 300 young alive and 200 dead young. Reproduction thus appears very low with a high mortality. Young were out running around. It is felt considerable mortality took place through our presence, since we prevented adults from shading young from the sun. On our visit to the gull colony on June 26 we did not [illegible] notice such high mor- tality among the young birds and wondered if many did not die after we left. so young were banded. Caspian Tern - This bird has not been noted nesting on the island by previous ob- servers. Apparently it is a new comer. There is nothing to add to the observations made on June 26, when the 25 tern nests were counted in the gull colony, except more of the young had hatched. Mourning Dove - The observation by Giles and Hygren on this bird on May 15 consti- tutes the only record. A pair were seen by them. Rock Wren - Rock wrens could be heard singing from the higher part of the island.
