DOWNLOAD EBOOKThis book looks at the Kirtland’s warbler and wildlife conservation in a way that no other book has. It looks back on the history of this unique bird, examines the people and policies that kept the warbler from extinction, explores the cult of personality that surrounds it, and examines the challenges of the future—all through the eyes of the people who have acted so passionately on its behalf. The story of the Kirtland’s warbler is a story of complex relationships between the bird and its environment, the humans who interact with it, and the complex government policies that affect it. And now, just when it appears that the Kirtland’s warbler has recovered for good, a change in its status may send the warbler’s population into a downward spiral once again.

DOWNLOAD EBOOKAbstract: This study examines prey availability as a factor influencing breeding habitat selection by Kirtland's Warblers (Dendroica kirtlandii), and characterizes the foraging behavior of this endangered species. Kirtland's Warblers nest on the ground in early-successional jack pine forests in northern Lower Michigan. The species may reject old jack pine stands for nesting due to decreased prey density in lower branches and ground vegetation of old stands. Insects were captured in young and old nesting habitat and in mature jack pine too old to be attractive for breeding, and birds were observed foraging in young and old nesting habitat. Insect biomass in low vegetation was less in old nesting habitat than in young nesting habitat, and was much less in mature habitat. Kirtland's Warblers in old nesting habitat did not forage higher than those in young nesting habitat, suggesting that the decrease in insect biomass in old nesting habitat is not great enough to affect the birds. Managed plantations and natural wildfire-regenerated jack pine stands were very similar in terms of insect abundance, diversity, and distribution, and warbler behavior. Warblers foraged most often on jack pines, but also used ground vegetation and pin oak trees as foraging substrates. The proportion of foraging attempts in oak varied widely among stands, suggesting that warblers use oak in proportion to its availability. Female Kirtland's Warblers foraged significantly lower than males, following a general trend for species of parulid warblers.
