Journal emerges from the snow cover, and is covered with standing water. Good pectoral country, going to waste. Found 2♂♂ and 1♀ pectoral there. They were trying this. 2 good ♂♀ classes, plus several aerial displays. Semi-pals common here. [Semi-pals are only Caliorine with numbers equal to last year.] Observed semi-pal and pectoral feeding in same pond. Semi-pal feeding along edge - obviously using visual cues. Pecking singly with visual search, moving and turning less, w/ "half-pecks" as if to see better. Even when jabbing- done mostly singly in loose litter with appearance of visual cues. Pectorals were probing in suspended litter- probably tactile cues. Probe rapidly around a spot, with no apparent search movements. 3-8 probes/serial. Could not have been aiming at anything in particular. Worse if pectoral has evident sensory organs or longer sensory trunk in bill than does semi- pal. Maybe able to tell by fixing and staining sections of whole bill. Have to check on this.
