"Ascending whistles" by a bird (male) that had displayed a few moments before. Note that when a bird behind me displays this bird gives a short whistle. Quality: 1-2. Level: +3. 203 tape. LN.
After a minute the female flew and thinking the male would fly after her without displaying, I turned off the recorder--and the bird displayed!! Then a display by the bird behind me, who had meanwhile been giving "ascending whistles."
203 tape. Quality: 1-2. Level: +3. LN.
