Thanks for the excellent information Jim! I wanted to also pass along a
caution regarding use of vocalizations. You need to pay close attention to
the quality of the vocalizations and not just the pattern, since LBDO's can
give multi-note calls and SBDOs can give single note calls. BNA Online
gives an idea of the range of Dowitcher vocalizations in both species:
Long-billed Dowitcher call generally described as single-noted sharp or
strident *keek* given as a single, double, or triple note by both adults
and immatures (Fig.
2<http://bna.birds.cornell.edu/bna/species/493/articles/species/493/galleries/figures/figure-2>);
Short-billed Dowitcher whistled *tu-tu-tu* or *teu-teu-teu* (Jehl
1963<http://bna.birds.cornell.edu/bna/species/493/articles/species/493/biblio/bib070>,
Lenna 1969<http://bna.birds.cornell.edu/bna/species/493/articles/species/493/biblio/bib078>).
Explosive alarm call of Short-billed Dowitcher may be mistaken for a
*keek*. Second call given by both species is
*to* or *tu*; given singly or up to 8 times in succession; similar to
shorter, flatter, species-specific *teu-teu-teu* call of Short-billed
Dowitcher
Good birding!
