the same species nearby.  Let us hope that this is not the reason why the Unduavi birds are so silent!!

It is highly probable that the "begging" by the Carbo yesterday was sexual. (Probably also true of the very similar performance by a single Cy at Nono.) Possibly a sign of unsatisfied copulatory motivation. Probably rare simply because it is unnecessary in, or even inhibited by, the precence of the mate. 

In the afternoon go along road from La Paz to Mecapaca. Reach a place called Cazeres, 10,125 ft, 3:15 pm. Plantation here in the midst of very dry country.

Noting going on. To outskirts Mecapaca itself. 10,050 ft. 3:45. Pure pear orchards

Lots of Blue Tanagers around. Apparently all in pairs. Noisy. Song rather twittering.

Go on back to La Paz. Same place as this morning. Arrive 5:10 pm.

One Carbo sitting quietly in hedge. Then flies away. Lands further down in hedge. Stands in diagonal posture with belly fluffed way out.

Apparently quite alone Then flies away, out of sight

What is this? Intention mov of "begging"? Or reaction to me? Is belly fluffing hostile in this species (viz the song posture of some glors).
