[[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.

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.

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.

[[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.

The sound of one bird singing might be considered a "priming" mechanism, getting another bird "ready" to sing.  Then the silence after the
