Ornithological Note 344

Notes on the vocalizations of Dunnock (Prunella modularis)

Section(s): Voice, Systematics

In the following we briefly analyze and compare voice of the different races of Dunnock (Prunella modularis). We also try to quantify the extent of any vocal differences using the criteria proposed by Tobias et al. (2010), as a support for taxonomic review. We have made use of sound recordings available on-line from Xeno Canto (XC).

Our main interest is to compare voice of race obscura (which is moderately distinct and has a somewhat disjunct range) with other races. We have located only two recordings of obscura, and to the ear these sound very similar to European races. A comparison (illustrated with multiple sonograms in the pdf version of this note): obscura (n=2), a few random examples from France, Germany, Belgium, Estonia.

All basic sound parameters for song of obscura fall within the range of other races (phrase length, # of notes, note length, frequency, pace,..). Individual note shapes don't seem to be unique either, and overall pattern of a full song phrase rather similar as well.

Based on the available recordings, we can conclude that there are no clear vocal differences.

This note was finalized on 28th April 2016, using sound recordings available on-line at that moment. We would like to thank in particular the many sound recordists who placed their recordings for this species on XC, in particular Fernand Deroussen and Marcin Solowiej for recordings of race obscura.
