(55) [[underlined]] Diglossa, [[/underlined]] May 25, 1962, V [[blue and pink marking]] Back to [[underlined]] aterrima [[/underlined]] area 7:43. Blue-spot sining. [[underlined]] Aterrima [[/underlined]] starts. Partly overlaps Blue-spot. Blue-spot stops. [[underlined]] Aterrima [[/underlined]] stops. Blue-spot starts again. [[underlined]] Aterrima [[/underlined]] starts again, partly overlapping Blue-spot again. Both shut up. Blue-spot starts again. Shuts up. [[/blue and pink marking]] [[blue marking]] 7:50 a.m. See parts of a long dispute between 2 Blue-spots. One chasing the other in air. Long twisting & turning flight. [[underlined]] Accompanied by "feeeet" notes. [[/underlined]] Then 2 birds land in same bush. One sings briefly. Hope around excitedly. Silent. One or both fluffed underneath, with tail fanned. One BW's 2 or 3 times. Then aerial chase begins. Again with "feeet" notes. Then birds apparently separate. Sing from perches appr. 50 ft apart. First synchronously, then alternately. 8:00 a.m. Arrive back Conebill area 8:12 a.m. A Blue-spot sings briefly. Then another. Then various Blue-spots sing from time to time time. Not very prolonged. No overlapping. [[/blue marking]] [[blue and pink marking]] There also seems to be at least one [[male symbol]] [[underlined]] aterrima [[/underlined]] in the area. Largely silent. Gives a couple of brief phrases when the Blue-spots are silent. Quite like the phrases of the other [[underlined]] aterrima [[/underlined]] heard singing here this morning. [[/blue and pink marking]] [[red 'C' marking]] 8:50. See a pair of Conebills feeding. Definitely probing at base of tubular flowers. Then one bird flies over to its mate, and apparently [[underlined]] feeds it!! [[/underlined]] No display. [[/red 'C' marking]] [[blue and red marking]] One of these Cornbills sang quite briefly when separated from its mate by a few yards (the bird who did the singing was the one who also did the feeding – i.e. almost certainly the [[male symbol]].) This seemed to provoke an adjacent Blue-spot to sing. Then Blue-spot shuts up. There was a pause. Then the Cornbill sang another phrase. [[/blue and red marking]] [[blue, pink and red marking]] The sound of one bird singing might be considered a "priming" mechanism, getting another bird "ready" to sing. Then the silence after the [[/blue, pink and red marking]]
