Age, arrival date and reproductive success of male American redstarts Setophaga ruticilla
We tested whether the age-related differences in reproductive success in male American
Redstarts are caused by differences in date of arrival on the breeding grounds. By relating …

Female-biased philopatry, monogamy, and the timing of pair formation in migratory waterfowl
FC Rohwer, MG Anderson - Current ornithology, 1988 - Springer
Waterfowl (family Anatidae) provide several exceptions to more typical avian breeding
systems. One exception is their system of parental care, wherein highly precocial young …

Effects of Spring Body Condition and Age on Reproduction in Mallards (Anas Platyrhynchos)
We explored predictive models relating body condition and age to nesting propensity, timing
of nest initiation, clutch size of first nests, aggregated nest survival, hatching success, and …

Raptor floaters at Moffat's equilibrium
WG Hunt - Oikos, 1998 - JSTOR
Explanations of population size often invoke density-dependent reductions in fecundity and
survival under conditions of Malthusian growth. An alternative, that territorial bird numbers …

Declining scaup populations: a retrospective analysis of long-term population and harvest survey data
We examined long-term databases concerning population status of scaup (lesser [Aythya
affinis] and greater scaup [A. marila] combined) and harvest statistics of lesser scaup to …

Declining scaup populations: issues, hypotheses, and research needs
The population estimate for greater (Aythya marila) and lesser (Aythya affinis) scaup
(combined) has declined dramatically since the early 1980s to record lows in 1998. The …

Nutrient Reserves of Lesser Scaup (Aythya Affinis) During Spring Migration in the Mississippi Flyway: A Test of the Spring Condition Hypothesis
The continental scaup population (Lesser [Aythya affinis] and Greater [A. marila] combined)
has declined markedly since 1978. One hypothesis for the population decline states that …
