D. PEARSON 1949 61 June 5 Collected all those in the cluster in North Tunnel. Saw some escape although one was seen flying afterward but not captured, checked band numbers etc. For details see notes of MK. About 2 were still preg and 1 (same) was non-preg non-lactating. Twelve were carrying the same babies as they were last week and 2 were not. Loose babies we put on floor of cave about 10 feet further in than where we were banding at entrance. All except one crawled immediately to climb up the side 1/2 to 3 feet. One into a crevice. They squealed occasionally, which attracted the attention of females that were flying about from time to time. All 4 seen flying were not carrying young. Baby bats not squealing audibly were not approached by females. There seemed to be a tendency for the babies to squeak more when the FF were nearby. Perhaps the babies hear supersounds but attract the FF with audible squeaks. On 6 occasions females came up and selected a baby, crawled over it "brooded" it for perhaps 10 seconds, then flew off with the baby attached. In each case the female rejected one or more of the babies after a momentary contact with it, then encountered one that gave every indication of "satisfying" them, and flew off with it. After several attempts, Mary finally settled one [illegible] after it had picked up its young. The baby was one that was unattached when we sorted out the catch. The female was one not in the catch I parts possibly
