California & Ringbill  Hatched morning June 22.

From hatching: (or at least drying) (a) short whistle
(b) long whistle
(c) monosyllabic distress call
(d) bisyllabic distress call
(e) complete distress call.

By third day, only the complete distress call and the long whistle common.

Distress call, during first few days, appears in any condition of discomfort: too hot, too cold, hungry, or uncovered. 
Mono-bi-trisyllabic progression is one of intensity

Whistle seems to be due to lesser frustration. Not given by perfectly contented birds. N.C. calls it some sort of pleasure note, typical, for instance, of a bird taken from icebox and put under lamp. Does it appear in bird taken from under lamp and then put in the icebox? Crucial question. I think so.

Gus and Willie haven't fought yet.

Noticeable that Gus (California) gives distress call much less frequently than Willy (ring-bill). Seems to appear at higher intensity of "frustration" in the former.

June 29th

Nothing much new. Distress call really polysyllabic. Gus and Willie both introduced to Franklin's chicks on the 27th, 28th, and 29th. No reaction - except casual pecking (as if at food)

July 3.

Willie still doing many polysyllabic distress calls. Gus doing very little in the way of distress calls. Even by handling
