K.E.Johnson 1968 June 23 Anchitka Island, Alaska (cont.) also found at the opposite end of the tunnel [east side of bluff]. Nests were of both species I believe. There are a few birds of large body & bill size which have little or no apparent red on the face & have only + lack the crests on the head the faintest trace of white on the flanks. At first it appeared that these might be Double-crested Cormorants. However since closer looks revealed these birds mated to others with more red or with more white in some cases & since the brightness of red on the face varies considerably, it seemed more likely that these birds were Red-Faced species, perhaps 1st year birds ('sub.adults') - but they were nesting. They tended to be mated to birds of similar coloration. Several of these were seen carrying nesting material to a specific nest, as was also on distinct red-faced individual. Nests contained eggs, small young, or large feathered young. Usually clutches of 3 to 4. Several dead nestlings & one adult Pelagic were seen beneath the nests. Pelagic Cormorant - present & nesting in lesser numbers than Red-Faced cormorants as noted above. Nests in the tunnel area were only 10 ft
