Fields of Specialization: Animal Behavior, Ornithology, Behavioral Ecology Research
Interests: I am broadly
interested in the reproductive biology and behavior of birds. Over the past 30+years,
I have studied a wide variety of topics including: |
|||
|
Ø
functions
of song Ø
nestling
growth and development Ø
effects
of ectoparasites on nestlings Ø
parental
care Ø
the
process of nest-leaving (fledging) Ø
adaptive
value of different egg shapes Ø
role
of calcium availability in limiting
reproductive output Ø
evolution
of plumage colouration |
Ø
criteria
that females use in
choosing mates Ø
causes
and consequences
of polygynous mating Ø
extra-pair
mating behavior Ø
manipulation
of offspring
sex ratios by females Ø
ovicide and infanticide Ø
effect of breeding at high altitudes
on life history strategies |

I do field work during the summer in
northern |
||
|
Most of my research has involved one model species, the House Wren. However, I also have worked with the Tree
Swallow and am now working on several projects involving the Mountain
Bluebird. |
