Observation details
Continuing near the entomology building. There have been differing opinions on this bird, and I think that much of the time it does give calls that are more equivocal. However, towards the end of the visit it gave calls more spontaneously (no recent playback), and those calls sounded more typical for Winter Wren. When I just first heard a call before it did any doublets, I thought it was going to be a Song Sparrow. Reviewing the spectrogram also shows a much broader call with an inverted 'U' appearance, which appears pretty classic for Winter. The fundamental frequency also appears lower, more in the 4.5-5 kHz range, whereas Pacific is higher in the 6 kHz range. It spontaneously gave a few short song stanzas. It would only do one, and then not sing for 15 minutes. Given that it was short and mostly isolated I hesitate to put much emphasis on it, however what I heard was shorter and sounded "richer" or "fuller" and might favor Winter. The recordings Curtis obtained of the song were while it was giving a very quiet song, unlike those isolated stanzas we briefly heard and didn't have a chance to record.
