Introduction
Sources for specimens
Burke Museum,
University of Washington
• Demonstrated well-preserved
tissue collection in previous
collaboration
• Houses voucher specimens for
tissues

• Boasts an “unsurpassed
modern collection from many
localities throughout the former
Soviet Union and Mongolia”
Specimen selection
No formal list has been
decided on yet for the
Palearctic
• “A Field Guide to the Birds of
Russia” was used as a guide to
pick samples
• Species were reviewed in
systematic order, searched for
in the Burke’s online database
(including specimens collected
in Russia, Mongolia, and
Kazakhstan)
DNA sources
Feathers are not useful for
initial sampling effort
Museums are the ideal
starting point
Maintaining a 96–well format
facilitates high throughput
Receive tissues in “Matrix”
boxes to help maintain
organization

Summary:
n=6
213 of 234 species
626 sequenced of 803 specimens
2.9 replicates per species
Mean intraspecific distance = 0.52%
(versus North American 0.23%)
n=1
Mean congeneric distance = 8.83%
(versus North American 5.9%)

Results: Taxon resolution
Only 1 “lumped” pair of taxa has been found:
Results: Species discovery
1 Anatidae
1 Scolopacidae
1 Columbidae
1 Caprimulgidae
2 Picidae
2 Hirundinidae
1 Troglodytidae
5 Turdidae
14 Species with splits

• NO Palearctic species LUMPS with a Nearctic species

Preliminary points
1. Patterns of divergence emulate
those observed in the North
American birds
2. The addition of Palearctic birds
does not confuse the results
from the original dataset
New contributions
Zoological Museum of Moscow
