Prairie Warbler: Comparison of Slight Variations
between the songs of 2 different warblers. |
 |
These
two Prairie Warblers sing slightly different songs.
Both sing the buzzy, ascending trill typical of this
species, in the same frequency range. But, the
song of the 2010 Prairie, with 17 notes, is
shorter than the song of the 2013 Prairie, with 23
notes. We do not know why, but there could be
several reasons: different dialects at different
locations, different times in the breeding cycle,
different experiences - weather, recent predator
encounters, etc., or simply just different
individuals. Notice that both birds sing about
the same number of songs in about the same amount of
time - 5 songs in about 47 seconds, so the slightly
shorter songs are slightly further apart.
