The reproductive success of tree swallows nesting near experimentally acidified lakes in northwestern Ontario
TLDR
It is found that near acidified lakes, eggs were smaller in certain dimensions, hatching success was lower, certain nestling body characters were smaller 4 days posthatch, nestling wing length was shorter near time of fledging, and growth functions were different from those near unmanipulated reference lakes.

THE USE OF CYTOCHROME B SEQUENCE VARIATION IN ESTIMATION OF PHYLOGENY IN THE VIREONIDAE
A recent phylogenetic study of the genus Vireo, based on protein electropho- resis, shows the taxon is polyphyletic and contains four distinct groups. This contradicts the traditional classificationExpand
Evidence Supporting the Recent Origin and Species Status of the Timberline Sparrow
TLDR
Results suggest that gene flow does not currently occur between these two forms and that each is on an independent, albeit recently derived, evolutionary course, consistent with theo- retical expectations of a Late Pleistocene speciation event. Expand
UNSUITABILITY OF THE HOUSE FINCH AS A HOST OF THE BROWN-HEADED COWBIRD'
TLDR
It is concluded that nestling diet may be important in determining cowbird choice of host and Lack of cowbird survival in nests of the House Finch appears to be the result of an inappropriate diet. Expand
Some sources of variation in the elemental composition of Bald Eagle feathers
Concentrations of Br, Mn, Na, Al, and Cl were measured in back and tail feathers and concentrations of Mg and Ca were measured in tail feathers of wild and captive Bald Eagles (HaliaeetusExpand
Metal accumulation and metallothionein concentrations in tree swallow nestlings near acidified lakes
TLDR
The results clearly provided evidence that metals are transferred from acid lakes to birds and that these metals are correlated with increases in hepatic MT production. Expand
