Factors related to northern goshawk landscape use in the western Great Lakes region Factors related to northern goshawk landscape use in the western Great Lakes region
Northern Goshawks (Accipiter gentilis) are a species of special conservation concern in the western Great Lakes bioregion and elsewhere in North America, and exhibit landscape-scale spatial use patterns. However, little information exists about Northern Goshawk habitat relations at broad spatial extents, as most existing published information comes from a few locations of relatively...

Do digestive contents confound body mass as a measure of relative condition in nestling songbirds? Do digestive contents confound body mass as a measure of relative condition in nestling songbirds?
Relative nestling condition, typically measured as nestling mass or as an index including nestling mass, is commonly purported to correlate with fledgling songbird survival. However, most studies directly investigating fledgling survival have found no such relationship. We weighed feces and stomach contents of nestling golden-winged warblers (Vermivora chrysoptera) to investigate the...

Retirement investment theory explains patterns in songbird nest-site choice Retirement investment theory explains patterns in songbird nest-site choice
When opposing evolutionary selection pressures act on a behavioural trait, the result is often stabilizing selection for an intermediate optimal phenotype, with deviations from the predicted optimum attributed to tracking a moving target, development of behavioural syndromes or shifts in riskiness over an individual's lifetime. We investigated nest-site choice by female golden-winged...

Redefining reproductive success in songbirds: Moving beyond the nest success paradigm Redefining reproductive success in songbirds: Moving beyond the nest success paradigm
One of the most commonly estimated parameters in studies of songbird ecology is reproductive success, as a measure of either individual fitness or population productivity. Traditionally, the “success” in reproductive success refers to whether, or how many, nestlings leave nests. Here, we advocate that “reproductive success” in songbirds be redefined as full-season productivity, or the...

Fall survival of American woodcock in the western Great Lakes Region Fall survival of American woodcock in the western Great Lakes Region
We estimated fall (10 Sep–8 Nov) survival rates, cause-specific mortality rates, and determined the magnitude and sources of mortality of 1,035 radio-marked American woodcock (Scolopax minor) in Michigan, Minnesota, and Wisconsin during 2001–2004. In all 3 states, we radio-marked woodcock on paired study areas; 1 of which was open to hunting and expected to receive moderate to high...

Evidence of territoriality and species interactions from spatial point-pattern analyses of subarctic-nesting geese Evidence of territoriality and species interactions from spatial point-pattern analyses of subarctic-nesting geese
Quantifying spatial patterns of bird nests and nest fate provides insights into processes influencing a species’ distribution. At Cape Churchill, Manitoba, Canada, recent declines in breeding Eastern Prairie Population Canada geese (Branta canadensis interior) has coincided with increasing populations of nesting lesser snow geese (Chen caerulescens caerulescens) and Ross’s geese (Chen...
